Thanks Norm,

No the choke works fine now after I sprayed some WD40 all over the levers. The only problem is it runs too slow even at full throttle just before the choke comes on. Seems like the governor is set too slow. There is a lot of springs and levers there and there is a screw adjustment I'm just not sure what it does yet. And the stop switch does not quite activate yet.

I'll study it a little more. Need to take some tension off the governor spring if I could work which one that is.

Anyway good progress so far thanks for your help.

All the best
Jeff
