Hello all, My J150GTLCUR 150GT has been giving me troubles, It starts fine but once
I go to throttle it up above 1/4 throttle it boggs and just won.t take off.So Heres where
I'm at! I have rebuilt all three carbs to the core! found lower carb had cracked tubes
in the bowl the ones that have calabration holes,I replace the carb but did not help.
Then I had replaced the primer bulb but used a cheap one which never got firm.So then
I replaced it with a OMC bulb,replace all fuel lines and I mean All! even the water sep,filter.even the valves in both gas tanks that have the balls that keep fuel from draining back to tank check valves.drained and cleaned both gas tanks,still bogging!
Then I replaced the VRO pump with new lines as well.with the new pump and OMC primer
bulb the bulb gets very firm now. tryed it this morning and still bogging.the gas tank vents are clean. comp. is and always was 92 lb's on all 6 cly's hot or cold! Not even 1 pound deffrent. I see when I fire it up in the lake it cranks easy. idels great at first then
as I take off it seems to had sputered a few times and then the motor idels up and if I throw it in neturel= it runs up near 2500 to 3000 rpms. so sort of a runaway idel?
Thought at first it was starving for fuel and leaning out but I have cleaned!rebuilt! and changed everything as said above. the only thing I have not done is a spark test and thats comming tonight. I pulled all plugs just now after running it at the ramp and they
all 6 look wet and the same . any help plzz.
