I expected that I couldn't get a manual for free - but they only want to mail it to me - which, since we use a mail forwarder, could take weeks.
How does draining the fuel in the carburetor help the problem - I don't understand. (Is it becoming obvious that I'm really no mechanic - just a cheap, struggling DIYer.)
Just found a link about Starbrite's Star Tron
. I actually have some and used it to forestall this problem - do I need to use more?
