Haha!! - FIXED!!!
Cleaned carb again, must have drawn more sh*t through from the fuel bowl (now removed).
Flap from governor is removed
All seems OK now! Nice smooth idle - impressed!
Thanks for words of advice and encouragement!
I will be commuting 120 miles a day now in a 20 year old £100 ambulance!!! (makes a change to a 38 year old scimitar I suppose!)
All good fun, beginning to quite like it actually, obviously sssooooo slow compared to the scimitar but then it weighs twice as much, has a tiny carb and lower compression so i will forgive it that until I can get a Chevy engine for it.......
Woohoo! as you can tell I am quite pleased!
