I purchased a 1987 Johnson 40 VRO electric start (J40TLCUD) that I converted to a premix fuel system because it wasn't running right. All new stuff--Bombardier "standard" fuel pump (PN 438556),inside and outside fuel lines & bulb, glass filter (before bulb), fuel tank, CLEANED and REBUILT CARBS(floats set level). Capped the old VRO pulse port. It runs OK at idle and higher RPM in my driveway when cold but let it set for half an hour in the Florida heat and it starts hard and will not rev up when you advance the throttle, like it's starvin, just like before all the work! Pumped the bulb-not much difference. IF I flip the electric primer lever from prime position to run, while idleing, the motor shuts down (Whats with that?). Timing is OK but it advances somewhat before butterflies open??? Compression is good. Noticed during carb tear down that, according to my manual, the carbs are for a 55 COMM??? (low,intermediate and high speed orifice) Haven't had it in the water yet, can't swim!
