Bought it a month or so back but finally had a chance to get on the water with it.
Things i've checked, replaced or rebuilt prior to taking it out on the water..
Good compression 100 psi +/- on both cylinders
Good spark, It will jump 1/2" gap with no issues
New plug wires and boots
Cleaned and set points to .020"
New J4C plugs gapped at .030"
Rebuilt carb completely with a kit so the plugs were pulled to completely clean it.
Fuel lines replaced
New water pump
Armature plate doesn't wobble around
I pulled the intake and checked the reeds, All were clean and apeared to be sealing. I did not completely pull the reed plate off the motor since I did not have a new gasket for it.
Checked the throttle plate opening correctly with the marks on armature plate. It starts to open right at the 2 marks
Didn't notice any oil around the upper crankshaft seal, But I did just pull it all apart last night and cleaned it, So if it does leak hopefully it will show next time I get it on the water.
Slow speed is about 1 1/2 turns out. If I run it with the SS needle out further it doesn't seem to make much if any difference with the sneeze, But does make a difference when I go WOT. When it's turned out richer it bogs down slightly when I go WOT.
Motor starts right up with one or two pulls and seems to run good except it will sneeze at low idle. If you crack the throttle slightly it doesn't do it and will go around the lake at low speed without any issues.
It doesn't have a thermostat. Waiting on it to get here. It still sneezed even after running it for 20 minutes or so around the lake and the water was warm coming out of the housing.
Sorry for all the text, Just wanted to try and get all the info the first time..
Any thoughts? something i've over looked.
