I got this motor from my brother earlier this year, ran good last year. I have rebuilt the carb,replaced the fuel pump, tank, and all the hoses, replaced no 1 cyl coil. If I give it a couple of squirts with the primer and advance the throttle it will start and keep running as long as it doesn't drop to idle speed. With a timing gun and turning with the starter motor the timing seems good and both plugs are firing. I have also gone through the carb several times and all passages seem open. I've run out of ideas. Any help would be much appreciated. compression is 120 on both cylinders
