    Soo glad I was wrong. Good job finding it. I likely would have started tearing things apart only to confirm nothing was wrong & have to keep searching.

    I watched a documentary about these new alloys. Many different options are being investigated. Some will recover with heat or cold. I can imagine body shops having a drive-in freezer to straighten sheet metal or park your damaged ride until winter. Self healing crumple zones. I doubt we'll see this in cars anytime soon. Maybe NASCAR could lead the way. It would make interesting pit stops.

    I soo hope I'm wrong but this sounds like an internal engine problem to me. Flywheels & starters tend to make more of a scraping sound which may or may not be intermittent. I wouldn't crank it with the starter until I pulled the valve cover & visually check out the valve train. Can't see anything wrong? Put a long plastic soda straw into each plug hole & carefully rotate the engine to TDC #1 cyl. compression stroke & check the cam timing. Watch the valves & straws while turning the engine & you may see the reason for the resistance.

    If you can give a detailed description of what you don't like about your ride & what you did like about the other, I think the members can give you a lot of ideas that can improve your ride & everyone has an opinion or experience they want to share. There are many combinations of springs, shocks & sway bars & they are bolt-in.

    First things first. I need to patch the battery size hole in the f. well before the b. tray goes in anyway. The damage is quite easy to imagine. Picture a hole below the battery that is about battery size & extends to about three inches from the frame rail. I can repair or replace the decrepit remains of the tray itself.
  6. Mark Maras
    I'd like to see what you have. My 260 project is still in need of that part including the battery tray.

    Hey Geoff I'm doing the "Snoopy happy feet dance" for you in Portland. Your description of a cold start is spot on. Sounds like you're very close to perfect. You're gonna love the carbs. Who knows, Maybe you can even convince Sarah that they aren't evil. Can't wait for the results from the butt-dyno run. So, is the new ignition sys. going to be installed, before or after the new build goes in? Great job. Mark

    Agree with Site. Start with a the basics. You mentioned previously the plugs were wet. The question is, too much fuel, weak or mis-timed ignition or a combination of both? Have you tried pushing the nozzles up on the carbs? These can become stuck & stay in the choke position. If the mixture is already set rich, adding choke (dropped nozzles) can make it blubber. I kinda doubt it's cam timing. It seems if that was off the engine would still be firing on six cyl. It sounded like it was firing on one maybe two at the most.
  9. Mark Maras
    What year is your car & what ignition system do you have? The more details you can include the better. I'd first check that each plug is firing. We'll take it from there.

    Odd, I checked my 260, Sept 73 build date. If the connector, under the hood, comes out of the harness below the ID tag, mine has two yellow wires & is disconnected. The only three wire disconnected connectors are farther back & are not yellow FWIW.
  11. Mark Maras
    Thanks, I'll add that to my list of descriptions.

    I think they have finally taken crumple zone too far. This is wrong on so many levels. The least of which is using Datsun's good name on a p.o.s.

    Please excuse my ignorance but what is the symptom of "lazy idle". I haven't heard the term used before now. It seems to be related to triples in this thread. The only triple setup I ever worked on was a 65 Pontiac GTO.

    I submit this for your consideration. IT IS NOT A RECOMMENDATION. Harbor freight has a solar light rope. Charge is good for eight hours, it's eight feet long & it APPEARS to be sealed. It might be worth taking a look at to determine if it is safe to use in that explosive atmosphere. It is possible to negate the explosive atmosphere in the tank with liberal usage of dry ice. I watched a crew burn a hole in an underground gas tank that had been removed. They dumped a lot of dry ice in the top & waited until the CO2 gas was visibly coming out of the top of the tank. One guy fired up the torch & as I was rapidly retreating to a safe distance, he burned a walk-thru hole in it. I was amazed. This too is not a recommendation. Just thought it was on topic.

    Don't panic yet. The first thing to do is set the rocker clearance. Then you can do a cylinder leak down test instead of a compression test. Out of place? Not to me. I once (back in the 70s) refreshed a 73 Z 4 speed in my apartment bedroom using a 4X8 sheet of plywood to (almost) protect the carpet. Trans. worked fine but the bedroom smelled like gear oil for a month.

    Having driven a 70 MGB, (mirrors located forward) sure you can see something, just not enough to do you much good. In all fairness, if you drive one long enough, it is possible to "adapt" to them & actually use them. I remember it was my sore neck(from looking over my shoulders) that finally made me use them.

    Siteunseen The balance tube is from an early 71.

    I agree, scale is a PITA. Concerning this spring, I wouldn't heat it enough to form scale, just enough to keep it from breaking. Air quench HMMM, I'll have to try that.

    The gentleman has that "I hate sanding" look on his face. I've seen it in the mirror a few times. Love the taxi sign on top. Uber vehicle?

    I removed what was left of the panel in question on my project 260. After patching the body underneath I made a new one out of 16ga. galvanized sheet metal. It hasn't been installed yet but the plan is to raise the forward part of the panel so it slopes to the rear of the car. I've fitted it & it appears that it will work fine. The body, in that section, appears to have rusted from the bottom up. Much more work to be done at the rear of the car. spare tire well etc.

    Hey Geoff WOW The SUs & everything are beautiful inside & out. Tuning these on Lilith should (hopefully) be easy. When is the set-up going to be installed? Are you going to install the new elec. set-up beforehand too? Rapid progress(outsiders point of view) & excellence are difficult to achieve at the same time. Good job on both. Mark
  22. Mark Maras
    I haven't seen the fitting you're looking for but another hose barb, the desired size could be attached to the f. pump using a short piece of flexible fuel line. I imagine it wouldn't have to be 1 1/2"-2" long & use two hose clamps.
  23. Mark Maras
    I normally use old engine oil. It actually will transfer some carbon from the oil to the surface of the steel hardening it in the process. Are you going to go for it?
  24. Mark Maras
    Makes sense to me. The spring had a purpose. I haven't looked at mine yet, but I think one could bend a new end on the spring using heat(very small & focused). It has worked for me in the past, The trick is in the cooling. If the spring is quenched too fast the steel becomes brittle, If you don't cool it fast enough it will lose it's springiness. I have found that a rapid quenching & then a slight reheating 350-400 degrees seems to work quite well. This a basic tempering technique used for knives & other tools.

    I didn't fully disassemble my linkage on my Sept 73 260. The spring in mine(if there is one) must be broken too. I assume, since it is a clock spring, it puts tension on the arm to hold it in the resting position. Now I'm going fully disassemble my linkage to see if the spring is there.
