Sounds like its running either lean or rich.If you have to pump it it might be lean.If you can start it without pumping it the its either rich or just right.Do like mike said and let us know.

My 12a used to do the same type of thing, I think its due to the hot-start assist servo being buggered.

I pulled that stupid motor assisted cable off.It did make it any worse so what was the point of it other than wieghing the car down?It met Mr. scrap bin along with alot of 12a stuff. :squint: :smirk:

It might be lean or the hot start assist isn't working at all.

try turning the idle mixture screw 3/4 - 1 turn counter-clockwise then try to start.

that should help
