when I first got it, it was badly set-up and ran like a dog, but I worked on it for a while and it appears perfectly OK. It's bright, starts easily and holds pressure... but it stinks. It only has to be running for a few minutes and it really smells... I'm sure many of you know that smell. So, today I changed the pricker and the jet, thinking it might be enlarged, adjusted the J-tube and the fine tuning vane so the fuel/air mix was as good as I could get it..... and it still stinks! BTW, it's running on 80/20 Amish mix - an attempt to aid full combustion - but that made no difference and I'm stumped. Has anyone got any ideas what I could try next?
