1988 70 hp evinrude

[moodys1st]

Hello, I have a 1988 70 hp on my procraft and have been haveing trouble at idle and throttle responce, slowly stalls at idle and stalling takeing throttle, i replaced all the lines and bubble, also put a fuel pump on it and removed the vro since previous ower had trouble with it, installed the fuel pump for a 70 hp, i put all new parts on the throttle linkage and tried to link and sink correctly, marks line up but i havent checked the timing at a low idle yet, carbs have been just recently cleaned and i pulled them off and checked everything again, all p***ages are clean. The motor will idle but when it sits idleing in the water it will slowly stall, when i crank it up and go to give it the throttle it bogs unless i rev it up and hit the throttle quick.


What should the timeing be at a low idle is it 5 degrees advance?


any ideas what may be the cause of this?

May be low on compression, check to see if all cylinders are even. May have bad reed valve or may have air leak in intake or crankcase half.
