Hi Grumpy,
After I made my last post, I found a similiar video. Better to ask a dumb question than to make a dumb mistake....
Anyway, I set the clearance to 0.005" and it now starts like a dream! Thank you very much for your help.
I looked again at the air cleaner housing and concur it is not the best design. I wonder if putting a small smear of grease on the seal would help? What do you think?
