Thanks grumpy, yes, this is about where I started. She will run and then I get her to temp. and set the idle and hi rev. but after switching off and letting it cool, she wants to be a pig and not start or revs sluggish. I will keep playing with it though. Pretty sure the rest of it is okay, diaghrams etc.
Yes, they seem very fussy and 1/4 or 1/8 turn or so seems to change things drastically.
Have fixed cars etc. for years but these small engines are another science altogether.
Cheers...
