I had exactly what you described. I put a tank of 98RON in and a full bottle of Wynns fuel system cleaner. This was a cheap fix for me. Now I idle at the lights and take off full tilt with no worries.

edit: your problem as described, only happened to me when I was getting up to operating temps. Once I was at operating temp the problem would go away.

Sounds like you need a new condenser.

Changed my carbi for another one today. Had to anyway as the last one didn't fit with an air filter attached. All idling ok but still have that problem of acceleration. It only happens as quoted above once it's up to running temperature it seems to go away. Might try and do the flush as suggested and see how I go.

Could it possibly be a fuel pump? I am pretty sure everything is working. But could be wrong.

Thanks for the help.

I'd be checking your timing, and the condition of your distributor internals...

I would also be looking at the condenser.

I should also mention, that my 'fix' for the spluttering while at the cooler temp was to run at idle with my choke completely open (so it revved quite high). I got much less spluttering when taking off at the cooler temps doing this. Now I just run with my choke completely closed.

are you using the choke when cold? too lean?

Moisture inside the dizzy cap?

are you using the choke when cold? too lean?

I think ill be doing alot of checking tomorrow to try and sort it out. thanks for the help.



Ill check it out



Thanks for all the suggestions. Really appreciate!!!
This does seem to fix it. I dont run it right open however it does seem to improve it with a small amount of choke.



I do use it however it doesnt seem to need it. It will usually start without it however may take one or two goes. But with choke it will start up almost every time. Could this possibly mean it is too lean? or still look at the condensers and dizzy caps.
