I thought it was just to supress radio emissions but it is actually part of a tuned circuit to improve spark and to minimize current damage to coil, breaker points or transistors.

Usually it is fuel system debris. Once i had a points car that had no power on load. I trouble shot for fuel only to discover it was the distributor.

I hope you are lucky like Dr 240z and I were. I did the old-school non-detergent 30wt correct break in on a new Delta reground set of rockers, Delta cam, correct new lash pads and new Crane springs and retainers with lots of break-in grease and great oil flow before first fire up. 30wt was again used at 50miles with a new filter. Mobile 1 oil synthetic was used after 500mi. The cam was eaten ~ 1,500mi. 2nd try was a new Schneider cam and new reground Delta rockers with ZDDP oil treatment. One rocker started to fail but it looked like a manufacturing flaw like Grannyknot's. Swapping in a refreshed rocker did the trick. From this experience I think the metallurgy, quality of the machining, spring pressure, and the oil additives are all important for correct break in and long life.

I like the custom brackets! Nice work.

6 may have dirt. Does it spit at idle or at higher rpms? If at idle then it would be the idle jet, or passage to enrichment screw or fuel filter. Flush it out well.

Could be dirt blocking fuel flow. Do both throats 5 &6 spit or just one on the last carb? What do all 6 plugs now look like?

Below 13 is "too stinky"

Seems reasonable to have those diagonals for oil. Could be a great modification. Thanks.

I still stink like a "cedar plank" says my wife,,, off to the shower btw Jim... don't ever listen to my friend Ross! I have another story that is just as crazy involving, border guards, Cadillacs, criminals and Datsuns. And another involving fire ants and an old man who did not have bladder control and datsuns...I kid you not.

Looks like you are getting closer...keep going!

3/4 turn iS for old webers. sk/oer is ~2 turns.... same as newer webers.

Well if all else is ok then you may wish to play with the accelerator pump stroke. It is externally adjustable on your carbs. If the carbs spit during transition then try giving more fuel through the acceleration pump adjustments.

For 160 km I tended to the fire.... Yup. My good buddy Ross bought 'Tootsie" a 1979 Datsun camper truck with L20. We drove 180km to Springhill, Nova Scotia in my brother's Civic who was going to be the sag wagon on the return leg. Ross is the kind of guy who just does things spontaneously so he bought the camper a few days ago when passing through Springhill on business after only a short test drive and today was the day to drive it back. He asked me to help and said it stumbled a bit as the owner mentioned and that the manifold had a leak so I did a quick check and we were on our way. It was immediately apparent that the double barrel Hitachi carb had problems with the primary. It bucked like crazy until we got the secondary to open so I suggested that he keep the RPM's up. It backfired a bit on deceleration so when we stopped for gas 15 min into the trip home, I looked at the plugs and they were perfect. I also looked at the timing. I did not have a light but I noticed the distributor was clocked fully CW so I rolled it back to the centre location. It ran like crap so I put it back to full advance....interesting. After about 15 more min on the highway we smelled wood burning. Hmmmm no electrical smell nor oil smell and the motor was working fine, must be someone burning wood...... so we continue..... then the smoke came into the cab.... where the hell was it coming from? A quick look back into the camper part and it was coming from the floor. I pulled myself back into the camper section much like a Lancaster pilot going back to man the guns.... flames were coming out from under a bench next to the propane heater!!!! I flipped off the top and also in there was the battery and DC to AC converter under the bench. I looked for an extinguisher and shutoffs for power and gas but there were none. Ross was unable to see the flames and said that he wanted to try to make it up the big hill that we were on as he was worried about stopping. I dumbly said to try it as I looked for a way to put out the fire then came to my senses and convinced him so stop. As we stopped, I jumped out the back door and headed to the snow bank to get snow to put on the fire. My brother, driving behind us just saw me jump out the door along with a cloud of smoke. The snow managed to put out the flames so we had a good look under the bench seat and under the camper. There was nothing electrical nor a pilot light in the stove. We disconnected the gas to be safe. I noticed no exhaust was coming out of the tail pipe so I looked for holes and could see none. The muffler was a good 6 inches from the floor and was close to where the flames were but we could see no indication of heat . I even touched the front of the muffler and the pipe running into it and they were just warm. We figured a squirrel probably sealed it up and the crack in the manifold was where the true exhaust flow was. We disconnect the battery and piled some snow in the area under the bench seat (which had another boxed off section inside) then continued on. After another 5 min at high rpm, the smoke would return. I pushed some snow around to cool the wood then the smoke would stop..... sort of like tending to a wood stove X -1. After 30min of doing this, I decided to punch a hole in the interior boxed section so try and push snow into that cavity... bad idea. the hole allowed more air in and the smoke got worse.... so we stopped again and checked for a cause. Again the muffler was just warm and so far away from the floor that we figured it must be something else. Ross pulled off some foam under the camper and could see that it was black from heat. I still thought it may be the muffler so I punched some holes in it with the claw of a hammer so as to let exhaust flow out the front ahead of the suspected squirrel condo. We then piled lots of snow into the smoky area and it stopped and we were on our way. 5 min later more smoke. by this time we had a huge pile of snow in the seat/bench compartment so I just tended to the fire, by stogging the snow into the cavities until we were close to the city (destination)... HOWEVER Ross yells back to me that the clutch is gone.... so I suggested double clutching and that sort of worked. By this time the snow had melted so I climbed into the passenger seat (bomber style) as we were worried police may see me not fastened in as we were coming into city streets. The the clutch went again.... so we had to shift without the clutch for the upcoming 6 lights with the truck bucking like crazy in first gear on the primary carb barrel..... then the brakes went. So we did what any bomber pilot limping back to England after being shot up would do.... we continued on. I worked the stick as Ross worked the hand brake and we tried to hobble through the lights by timing the colours and bucking as people on the side walk pointed at us and laughed. We just had one light to go in first gear at 5000 rpm running on the secondary when there was a huge backfire and the engine stopped. So we coasted to the side of the road and figured that was it,,, just 2 km from home. So my brother stopped and we had a good look around. Not much to see. Time to throw in the towel.... so being an "right EEEgiot" I pulled the breather off the carb and noticed a puddle of fuel at the bottom of the primary... mystery partially solved. I then noticed the plug to the coil had come off. The huge backfire (like a direct flak hit) out of the corresponding huge crack in the manifold apparently was powerful enough to blow the adjacent plug wire off the coil. I put the wire back on and asked Ross to crank. Amazingly it started.... and the clutch worked,,,, and the brakes work (I credit this to prayer to my guardian angel). So we made it all the way back at high rpms with people still pointing and laughing... but we made it.... and that is all that matters. I looked again at the muffler and it was a bit discoloured near the rear section. It looked a bit oranger. So I threw snow on it and it sizzled,,,, but not on the front. It was in fact glowing orange!!! Mystery solved. So here is the guess: - Timing too retarded - Primary leaking fuel into the exhaust stroke that collects in the back of the muffler and burns slowly heating the metal floor directly above it...which heated the wood. I then took my brother to dinner where he laughed at my wood stove smell and said that it was funny seeing me open the door and jump out with the plumes of smoke. Any trip with my buddy Ross is an adventure!

This is what came out of my friend's tank who suffered from debris causing his car to randomly die..... just a few flakes. Try not to be deceived. When your car dies, check immediately for spark and also check for fuel in the bowls.

I have read +60 to +80. It depends a bit on the emulsion tube.

Thanks mike! That WYSIWYG switch worked great. Also I dug deeper and the image quality issue is mine. I use a netbook and I have the scale for displaying this site at 60% thus all images are scaled down when viewed. No need to do anything but kick my behind when we eventually meet. Sorry for that!

We are all experienced enough to know that arguing on-line is a waste of time and usually makes us all look foolish... been there done that sadly. I think the best way to help others is to post accurate data based on scientific methods or many statistical observations when possible. If one has data to refute something just post it and be done with it. Try to add rather than take away. Let the readers of the future take what they want. We have nothing to prove.
