B&S 190402 engine problems
I have a 8HP Briggs&Stratton SnowGaurd engine that I cannot get to run correctly. It is on a 1975 Gilson snowblower. I had to put a new carburetor on it because the old one was leaking really bad. The new one will get it to run but not very fast. When I throttle the engine up and turn the mixture screw in, the exhaust gets red hot and shoots flames out of it. I have already done a valve job to it but it did not help very much. Any help with this would be very greatly appreciated.
