Hey guys. I'm having an issue with my 130HP 2-stroke. After warm up and running wide open, if I slow to minimum throttle in gear, I get a coughing, spitting, sputtering, whatever you want to call it. Sometimes the motor will even stall out from it. It's almost like it's misfiring but I'm thinking it has more to do with lean fuel mixture. This ONLY happens at slow forward ... at high speed, everything seems to be fine. Reading up on it in my shop manual, the most likely cause seems to be a thermostat problem with the engine running too cool. Under this condition, fuel will puddle in the crankcase causing a lean condition. So I'm thinking I need to change out my thermostats (vernatherms actually). I'm having a hard time determining whether I need a 105 degree thermostat or a 143 degree thermostat for this engine. Does anyone know where I can find this info? The Clymers manual is of no help on this.
Thanks in advance for your help,
