There is a little figure 8 extrusion in the HVAC area of Home Depot and maybe other places. We have trimmed one of the "O" in two with razor blade and glued it into the groove. Go eyeball what they have.... You can trim the other "O" put it on ebay and get rich.........

Post on the garage wall "needs lots of things done before turning the key". One wrong shortcut can cause gobs of costly repairs......

Listen to Guy. He has Guido and Luigi on speed dial too.....

And the really odd part of the two sets in this thread is they are both old variants of what the previous owner built many long years ago. Neither had much if any miles on them but both were machined and bearinged the way Scott did them. We re-did them for a price the way Steve currently does them and know full well they will perform flawlessly. Just stay away from the damned floats....... Put you hands in your pockets and back away!!! Guido and Louigi will be by for a visit....

The Z money pit, as large as it may seem isn't nearly as wide or as deep as the Datsun Roadster pit....

We have heat shields and new return springs....

Have you done a visual on the lines back to the tank? Any other fuel pumps along the way? Any crimped lines? Blow air thru the lines and have you wife listen at the fuel neck for bubbles. Did you add gas before starting this latest go 'round? Just askin what should be the obvious..... Send us your old fuel pump..... nyuck nyuck

Well then that shows, in large part, the workaday differences between Hitachis and what you have. With Hitachis you could have made things right without even removing the air cleaner. Not lambasting webers, they are what they are, but it would be interesting to hear what you end up having to spend to get them right once you get them home....

Why do I even bother........

As you reach lower altitude it'll start popping thru the carbs. That lean. Like has been stated just drop the nozzles like a half turn per and you decend. the carbs will let you know when they are happy. You start blowing black smoke your fat. take the nozzle back up a tick. When you get 'em home pull them off and see if they are our carbs. There will be an inscrition on the butterfly saying they are our carbs. If so we can maybe help determing if they have undersize noozles installed for the hogher altitude.

Nuther possible clinker in the mix that could limit the amount of fuel to the carbs in addition to the other things that have been mentioned. Inside that humpy casting on the float bowl lids are what are called Final Filters. They are fine mesh screen filters that if plugged with the infamous "sitting around crapolla", could be the culprit blocking adequate flow to the float bowls especially at speed. Take the banjo fitting off and see what lurks inside and when you put it back together make darn sure those washers re-seal or you'll be puking gas on that hot thingy underneath......

Nancy, May I call you Nancy? If you have a "restorer" and a "mechanic" that you're going to be writing checks to, chances of your being able to make this car pay out just went to Zero. Like has been said here, you don't want to end up with $30k in the nicest $10k car around. If you do, send me the check and we'll shorten your wait cycle by a whole bunch and get you a better car in the bargain.

Run the holes with NPT taps and they'll readjust the threads just fine and NPT plugs will work...... just fine. Maybe ad a spot of sealer. In the words of Gunnery SGT. Thomas Highway "You have to learn to improvize, adapt!

Questions: Why, if the car has been in dry storage, is the rubber in such needy shape? If the black is in decent shape what would fixing the door run you? I think I'd pay more attention initially to finding out how all those mechanical systems are before down loading a bunch of cash on cosmetics. Funky drive train in a pretty setting is a geranium planter. Just points to ponder and worth exactly what you paid for 'em.... Carry on....

Well, there you have it sports fans. The new owner, thru sweat equity, can do all the work that never would have penciled out. Win win. Some days things just work out.

That's kinda what I thought. I'd say if the cleaner isn't caustic you'd probably be alright. A little "shaky shaky hot bath" to drive the grunge out of the nooks and crannies ought to be a good thing, right? It's not going to attack the surface conformation of the aluminum pieces like media blasting so I'd say have at it. Linkage plating shouldn't be affected either, I'd suspect, that is if you have any plating left after all these years....

What is the purpose of the ultrasonic machine? What does it do, how does it work? Any heat involved or dangerous chemicals? Fire and/or ice? pressure and/or vacuum? What else am I missing? Getting the correct answers generally involves asking the right questions. That reminds me of a story relative to asking the right questions. Got a call back from a 510 owner who'd bought the JUST SUs DVD and some float bowl lid gaskets expressing dispointment that all the DVD talked about was these 2 side draft carbs. His 510 had this one down draft carb. Well, there are enough 510s out there running around with dual Hitachis on L motors that I just assumed A. he had one of them and B. If he didn't have one of them, he wouldn't have been on the phone to us in the first place. This camp counselor job can be tricky, very very tricky.

Now take out a pencil and a clean sheet of paper. Write your name and the date in the upper left hand corner...... This is a quiz and it will be graded!!! nyuck nyuck While you are in the "amass the wealth" mode I'll tell you what i tell a lot of owners. Buy the JUST SUs DVD and some float bowl lid gaskets, get three or four cans of carb cleaner and some rudimentary hand tools, borrow a couple of your wife's best bath towels, sit down at the dining room table and go thru yours. Once you have them on and dialed in as best they'll dial in, #1 you'll then know just how good they are and #2 you'll have a fairly good indicator about how strong your marriage is.... Seriously, all you guys, this Try it Yourself program will go a long way in shortening your learning curve on the carbs and by doing it and yours work fine, then you just saved a whole wad of dough....

The reason you can't find any dash pot gasket is........ The dash pots didn't have any gaskets. How do I know? Mmmm just guessing. The big question for me would be why do those two companies have four screw dash pots in stock?

Take the $2800 and run. If you paid someone to do all the rust repair and paint and added that to the $2800, do you think you'd recover the fix $$? But wait!! There was a 280 on here awhile back valued at like $19K..... oh, yeh that was by the owners insurance guy..... Sorry. C'mon Spring. Some of this stuff is making me goofy.

Stephen, I equate the early FI system to the flat top carbs. Both had shortcomings when new and neither has gotten any better with age. Talking to Steve on the subject, the second gen EFI from the Z was a much better system.

Yep, we can do 'em here or ship the pieces. unhook the FI harness and put in a low pressure fuel pump. From there it's a bolt on.

Therein lies why the EFI to SU carb swap is such a nice piece of business for us. On top of the limitations of the early FI system, they arfen't getting any fresher with age.

In Ct. I'm assuming a summer time driver? Is so it shouldn't affect anything. Winter driving, possibly. If they are four screws you didn't have water into the carb bodies like the three screws had anyway.....

A lot of owners are taking that degrading water system out entirely. Just another thing on these old pots that'll leave you standing beside the road out of water.
