Dear Grumpy

I am very grateful for your help. The engine is working like a treat, I've adjusted the carburettor as per your advice. Its great.

fyi where I came unstuck was that I didnt realise the play (lotsa) from the accelerator lever resulted in such a small amount of movement on the bellcrank. I was always getting that movement but thought it was just the choke action. hahahha what a goose. Ive learnt/relearnt alot in the last day and will now move on to the whippersnipper, outboard, the spare victa 2 stroke and maybe even get the methanol out for the model airplanes....

better mow the lawn first or I'll get the cold shoulder

cheers & thanks
