I referenced the B&S website and my other slightly different B&S engine and I know I've got the mixture needle in the ballpark.

For the carb cleaner, what's the worst that can happen, it flashes a little bit? Also, the carb is a manual choke.

For the engine model number, I haven't even found it on the engine.

I can't tell exactly where the fuel comes into the carb. The carb is mounted directly to the top of the tank though, so I suspect it is as Al says. I guess I'll just have to pull the thing apart and figure out how it works! (unfortunately in is like in the 90's outside today making for miserable outdoor work).

One question I had was is it possible it is the gas cap not venting properly and making a lower pressure when the engine tries to pull gas in? Maybe I can try loosening the cap to give it some more ventilation.

Once again, thanks for all the help. I'll try to figure out if there are any problems with the fuel supply.

Also I was wondering about one more thing. There is a rubber hose (maybe 3/8" diameter) that runs from the engine (upper part, but not on top) to the choke area of the carb. Any idea what it is for?
