Stalling problem - 36hp · Aussieveedubbers

squizy · 2008-08-10T11:19:28+00:00

My car has developed this intermittent stalling problem. When you turn the car over it will idle for anything up to a minute and then just stop. It doesn't seem to starve of fuel - it seems to lose spark. I've swapped over the fuel pump, carb, checked the timing, blown through the fuel line, condenser - and it still seems to do the same thing. It has a new coil from about 10 weeks ago, so that one is ruled out. I've spoken to a few people including Damo, Craig & Matt (thanks for you help so far guys), and we were thinking that it may be the internal spring at the bottom of the dizzy - so next step may be to just swap the who dizzy out and go from there. We also thought it may be the carby with a faulty float - even though I've swapped over the carb - and perhaps have the same problem?? We even thought it may have been a faulty tap on the fuel tank (between upper and lower pipes) - but we haven't yet taken the step of clearing out the tank. The car was intermittently ill and Valla, which I cured yesterday, but it seems to have come back again - even with all of those changes. Any ideas??? Also just a big thanks to Dino for bringing our tribe home from the Glenmore Park Show after we left the car at Monster, and also to Damo and Matt for perservering this afternoon / evening.

not yet, squiz needs to do the tappets first to rule that out. No use compression testing if the valves are riding open !

it wont be electrical.......it will be fuel or mechanical...........more likely fuel issues.

So last nights tests....the rebuilt carby that we tested running ok on Craig's 61 didn't run last night. So....there is defintely a fuel delivery problem.

I think what we've had has been an initial problem which has been fixed, and now we've introduced another one along the way. My 20c is now on the fuel pump I put in last Saturday week, which has shat itself on Sunday after the Hot Rod show. I will put my old fuel pump back in tonight. Cross fingers.

Only one way to fix is to start at the front and pull tank clean it

then blow out fuel line and move to back of car and continue

I read it on FACEBOOK so it must be true

That's the next step after tonight Dave. We've done pretty much everything else. Even the "Carby King" is scratching his head.

I have had this happen with my Grey oval. Hit a bump and faulty ignition shut down the motor. Turn the key and started back up no problems.

If you think it might be fuel replace the short fuel line from tank to tunnel. In my blue 64 this bit of line went soft and was sucking flat when after the engine was running for about 10mins. As soon as the motor stopped the vacuum in the fuel lines was released, fuel line opened up and fuel flowed again. Replaced the pump , dizzy , & fuel lines in the engine bay before I worked that problem out. 😬

Fixed.

Initial problem was shit in the carby. A "new" fuel pump was fitted by squiz thinking this may be the problem, but it wasnt, it ran the same. Then a borrowed carby was fitted, fixed! Ran a dream. But, on its first run with the new "new" fuel pump, the pump shit itself, but it gave the same symptons as the initial prob. So, the fuel pump was never checked again because it was "new".

So, the actual first prob was the carby, but replacing the fuel pump caused a second problem not known to anybody. The first problem was being chased but it was fixed by rebuilding the carby, only the fuel pump died in the meantime. Very confusing.

Amen to good friends and patience.

A big thanks in no particular order to Damo, Christie, Craig, Matt, Dino, and everyone on this thread who've passed on words of wisdom. We've scratched our heads, scarred our knuckles, sworn our heads off, kicked spanners, swallowed petrol, and finally worked it out.

Remind me to have a Jagermeister tonight to forget the taste of petrol.
