Brian - did your snow melt away up there yet? Hey an acceptable repower for a 782 would be a KT17 Series II. Don't know what else may fit but hopefully someone else will also pipe in here.
Jeremiah - well, I didn't exactly explain how it works, but since you commented here goes - 1st off, it has a wire that extends as you rotate the rpm numbered wheel. The wire vibrates either side to side or up/down. As you extend the wire this movement begins to increase then narrow down and will actually change from side to side - to the up/down motion. The sweet spot it right at the point where the direction changes. The movement will start a looping motion and you can narrow it down or widen it but very slight rotation of the wheel. The mid point of the looping size is the actual rpm's. It's pretty neat and known to be very accurate.
HEY - thanks for the info on the studs to. I re-read my post and said bolts where I meant studs so I'll clarify. I also didn't mean they should be bottomed out, just close cause they will rust/freeze in place and can be a pain to remove next time.
Bill J - I think the studs should be close to the bottom of the threads but not tight. Jeremiah mentioned backing off a 1/2 turn which sounds good to me. As I noted before, you also have to consider if the top of the stud is going to be used for anything else, like the gas tank mount, spacers, washers, split or lock washer, and the thickness of the nut you're using.
HOW BOUT SOME PICS!!!!!
Brandon M - there are still lots of SAE30 detergent oils out there. You apparently just haven't looked in the right place. Most NAPA stores have it on the shelf in several brands. You can get it from the sponsors that's specific for these small air cooled engines (very likely low ash content), etc.
