Solex or Weber? If it's a Solex, get a Weber...

Sounds like a vacuum leak. Do search on same and there are lots of helpful threads

Replaced vacuum lines ... And found leak in fuel hose... Runs great now thanks
So, does that mean it was a vacuum leak?
By the way, I merged your two threads. Please only post one thread per thought. And only one thought per thread. If you get what I mean :D

Will do in future kinda combined the threads .... Sorry.
Vacuum leak and a fuel leak ....
No worries, I just wanted to remind you, was all...
Glad you found the culprit. SO many conditions get blamed on a vacuum leak that are something else altogether, but yours just seemed to fit.
