Default RE: Carb too small? How do I know?

That actually helps alot, now I know which screw is the idle. What's odd is that I got it to get to a decent rpm by leaning out the idle all the way, but that would explain how come if I went lower than half throttle it would die. Guess I need to richen up the idle and lean out the high some more. I believe the correct proceedure is to set the high mixture first then adjust the low, then readjust the high, readjust the low, until they both kinda fit. Did I get this backwards? I'll try to find that thread you mentioned.

I looked up the carb this one has, it's an 8mm for sure. Like I said, it ran pretty darn good, suppose the numbers will tell the truth as I doubt I can accurately guage performance on an unfamiliar engine by ear. Can't wait till tomorrow, I want to see what kinds of numbers I get. I'm running a 16x8 right now but will likely switch to a 16x6. I seriously need to balance the prop, the vibrations were horrible and the whole time I was watching the fuel splash around the tank. Like I said, bad, no way I'd put it in a plane like that.

What kind of starter are you using? My standard 12v wasn't up to the task at all. I don't much like the idea of buying a high torque starter when I'm already on a slim budget but I guess thems the breaks. I've heard of people using drills with an oversized starter cone chucked in, might try that option.

Thanks again!
