Ok here is what i have. J60TLEUA 60Hp Johnson, its on a 20 foot pontoon boat.
Its hard starting, smokes like hell, dies a few times, then i get the oil cleared out of it and its ok. It will idle, but it shakes the boat, and the motor jumps up and down, only when in gear. If its not in gear you cannot notice any misfire. Above I would say 1/3 throottle the problem seems to go away and it runs good. Primer bulb stays firm all the time. I did check timing and its 5 degrees after TDC at idle in gear. I took apart the carbs and cleaned them, there were spotless anyways. I did notice the red lever on the primer solenoid is cracked, so i will replace that.
Here is something else i noticed while timing the unit. It seemed as if #1 missed a beat when the engine shuttered. Now i dont see it when the unit is on the muffs, but there is no load at that point either. So am not sure if a coil can drop out at low RPM like that?
Compression is good 115 in all 3 cylindars, when warm.
I forgot to mention, after i clear out the oil and it runs, then it starts all weekend ok. the next weekend is when it is hard to start again. thought it was probably the VRO leaking oil slowly so i now have that dissconnected, but havent tried to start it since then cause now its to damn COLD.
any ideas?
