Stalling under power ! HELP !

Post

Back to the top
When running the car, and giving it a little run during the weekends, I seem to have a little problem. When the car is under power in 2nd and 3rd gear, 4th and 5th not affected, it seems to judder as I accellerate harder throughout the gears. If I back off the power for about 10 seconds it seems to be ok, until you hit the power again. A freind of mine thinks this is fuel strarvation, not sure if this is right, as the pump etc has been replaced and the car has been tuned. I was thinking this could be a timing issue ?!?

I have looked at various images on the internet of how the HT Leads connect from the dizzy cap, and the correct number set up- could some one confirm the number set up from the cylinder head to the dizzy for me ! Having seen various images on the net- it would seem by HT lead set u[ or should I say my dizzy cap is on 180 degress the wrong way- would this cause this issue? I mean when comparing the images I found, to my set up, numbner one HT lead and the other leads seem to be the wrong way round !

I have also cleaned the carb out, replaced the fuel lines, and installed a new coil.

When removing the fuel filler/ float I can see that there a build up of some rust in the tank- which I know won't help it much, but I have installed a filter system in the tank to catch any rust particles.

If any one could perhaps show me a picture of theirs i'd be most grateful -thanks for your help in advance.

Thanks for the reply, sorry not had a chance to look until now !

So basically what that thread is saying to me- is to fit a restrictor the y piece plastic connector in the fuel line, and do away with the fuel/ vap pot? Would this be your understanding of it ?

I'm guessing this is why webcon make this y piece which includes the restrictor? Thus forcing more fuel up to the carb, and less of a return to the tank?

This is what my understanding is of the thread. I think I'm having the exact same issue, and I have carried out the exact same work too !

Can any one on here confirm if the vap pot can be done away with and this y piece is a good enough replacement?

Thanks Jp

to test if the restrictor will help remove the pot and block the return, if it runs great try refitting the pot with a restrictor in the fuel return
