Hi folks
I have a PB650 BLOWER. Engine starts, 2nd pull cold, runs like a champ for 10 min then runs up and down till stops.
New carb, New plug, New coil, New gas, ,New fuel lines and filter, tried with cap open. Compression is 150 hot. Im at a loss. Any suggestions would be appreciated. Thanks in advance

First thing I'd check would be that new fuel line feeding from the tank. It can be a bit tricky, but the new line has to be arranged in such a way that the filter lies on the bottom of the tank. It's quite easy for that pickup line to get kinked or curled so that the filter is up off the bottom, and ten minutes after you start the machine it "runs out of gas." Sometimes a steel nut or two (for weight) placed over the fuel line behind the filter can help.
