OLjo here again.Im having posting problems with my old computer,sorry about getting back.like I said before.my motor runs great at home on the water ears,but in the creek takes on a whole new deal!Spits and sputters,hard to crank,sometimes it'll runout sometimes not.The local mechanic replaced reeds and gaskets and got it a little better.Now it's not spitting gas back .He say's the compression is good.We've replaced needle valve"s and seats,the carbs are in good shape,very clean,from twice off the motor,they are seating good.When I'm at the creek and Idling I can see all 3carbs getting gas at about the same amount.What about spark advance?Think I ought to adjust some today when I try it? I replaced the rectifier at first because dirt dobbers helped rot the wires.As soon as I got it goin it would not cut off,so I ran my own cutoff switch according to I forget Who's instructions,which is working.Ive checked the coils with a spark tester and I'm gonna get the wife out after while and look at the plugs while it's running,,after I tape up my channellocks real good! The motor did set up for a year or so befor I bought it,which was last fall and I didnt carry it to the water,but it cranked good at that time. thanks for any help in advance.Any body got any low budget ideas I can try befor I carry this back to the man?
