I’ve been a long-time participant on the 6-Pack forums but never posted here before. Hopefully someone on this forum will have some ideas on how to solve a problem that has literally been keeping be awake at night for the past 2 nights. 6-pack forum has been really helpful but it seems like we're running out of ideas at this point.
About a month ago I took my 73 TR6 out of winter storage and began an effort to refurbish the engine compartment on the car. The car itself was running reasonably well before this work but there were definitely some things that needed addressing as long as I was in there. As background, here’s a list of what I’ve done to the car in the past month:
- Remove the distributor and have it rebuilt by Jeff at Advanced Distributor
- Remove, clean and rebuild the carbs. Didn’t rebush them but all other seals were replaced. The existing needles were also reused.
- Remove/repaint the brake master and servo
- Remove and clean the clutch master
- Remove and clean the alternator
- Remove, sandblast and paint the exhaust manifold
- Remove and sandblast the intake manifold
- Remove the starter and have it professionally rebuilt
- Repaint various parts of the engine compartment where 15 years of summer use had taken its toll
- Clean and polish everything I could get to
- Put it all back together with new seals and fasteners wherever necessary
- Set the timing statically using a voltmeter to detect when the points open on cylinder 1 as per the manual
Thing is, not the car doesn’t run at all anymore. With the choke out it fires right away when I turn the key but it only runs for 1-2 seconds before dying. I managed to get it to run for 5 seconds once by gingerly tapping the accelerator but that was a fluke. It seems like it catches, starts to come up to speed on its own and then dies every time.
My assumption, given that it catches at all, is that the problem is in the fuel system, not the ignition system. Last night I pulled the carbs and went through them again checking that all ports are clear, the diaphragms are seated properly, the needle valve is working, float height is correct, float chamber vent mechanism is working fine. In short I can find nothing wrong with the carbs.
Looking for any ideas on what to look for next as I’m fresh out of ideas. I’m going to block off vacuum the hose to the brake servo just to make sure I don’t have a massive air leak there but, again, it was running fine before I “fixed” it so I doubt that’ll be the problem. I really didn’t change much, mostly I cleaned, painted and resealed things so I’m really stuck trying to figure out what I messed up.
