5 hp briggs stalls under load
My Briggs 5hp tiller is giving me fits. The engine is a 130292 0706 01, c.1975 or so. Last year I pulled the carb off and cleaned it thoroughly and it ran beautifully, but it's been acting up a lot again recently. Today I find it nearly impossible to keep it going under a load. It starts, idles ok, runs smooth at full throttle, but quits as soon as I engage the tines. I have fooled around with the choke position and have saved it with the choke pulled but eventually it quits again. I can't get more than a few feet along without having to restart. That's pretty frustrating. The gas is new (couple of weeks) but I haven't pulled the tank off before so maybe there's some junk in there. My question, why does it run well in neutral but quit in gear? Any and all suggestions will be appreciated. I've got a couple of hours tilling to do, and look forward to your expertise.
