Thank you both, however, I really don't have the extra cash for a service manual right now. I just got laid off from my primary job, so now I am resorting to my handy man skills to get by. I installed the float, and got it somewhat adjusted... it runs like a top after it has been sitting for a little while, but then, the power starts to diminish, which tells me that the float bowl is not filling up fast enough, so the float is set too low, so some minor adjustments, and all will be good to go there.
As far as the expansion chamber goes, I started a fire in my parents fire pit, got a really good bed of coals going, then I added some wood to prop the expansion chamber on, and I got it red hot, then flipped it to get the other side red hot. I tapped it with a rubber mallet after it cooled down a bit, and then shook out the loose burnt carbon deposits. then i wire brushed it, and painted it with flat black 500 degree high temperature spray paint. Looks great, and I'm getting better performance out of it!!! Now I need to buy a new headlamp bulb for it. cant seem to find one anywhere anyone know where I can find one? its a three prong 6volt head lamp, aprox 5 in round. thanks!
