Model=252707, type=0145-01, code=79021911 mounted to a Murray frame. Ok, I did a search for this problem and read a bunch of older threads (though still pertinent) and can't find anything quite like whats going on with the engine I have (I just bought the tractor at auction so don't know the history). The motor runs fine at idle but once the throttle goes to full it surges. The first thing I did was to take the carb off and give it a thorough cleaning I Didn't soak it for a day but did take out and clean all needle valves, jets,etc then put in new gas and it still surges (I did set the idle and main screws so the engine runs like a dream). I watched the governor linkage and it is fluttering so I held it steady and viola' the motor ran like brand new (I had a friend old it steady while I adjusted the main). At this point I'm not sure if the problems is in the carb as I would think it would run bad if I held the throttle linkage steady instead of letting the governor flutter it. So at this point I reset the governor arm to no effect, I replaced the governor spring same thing, also made triple sure all the linkages & springs are in the correct place. Kind of looking for clues from here...I suppose it could still be in the carb but I'm a little skeptical at this point. I did buy a carb kit but don't want too use if it's not necessary. I'm wondering if the governor weights are somehow sticking a little in the engine???? it seems to throttle up and down fine though. Thanks for any help! Doug

I have an older Craftsman 11HP garden tractor with a Briggs & Stratton 11HP engine that apparently blew up. A loud pop and now no compression. I bought what appeared to be an identical engine from a guy and it bolted onto my tractor perfectly, all the connections matched EXCEPT: the old engine had one red wire coming from behind the starter, with a single quick connect plug and the replacement engine has 2 wires coming out from behind the starter, one red & one black in a 2pin quick connector. How do I go about hooking them together?
