Re: Service manual needed
Here's a site that has quite a few manuals in pdf format and for five bucks a shot. I don't see your specific manual in their list -- or actually I get a 404 error -- so it may take a bit of fingerwork on your keyboard to find a manual which may be listed for some year other than yours, but is identical, or essetially idencial, to yours. I've used 'em as recently as yesterday.
And another thing: ya know, these little engines ain't exactly rocket science. While it's nice to have a shop manual around, and I do like to have one, there is a huge amount of information on the 'net about the engines that just a few years ago wasn't available. The best example is umpteen dozen sites that present microfiche drawings of the whole engines, often with very helpful additional information in the parts descriptions.
So for $40, I'll figure it out myself. But for $4.95 delivered to my computer while I go get another cup of coffee, it's nice to have.
