engine will not idle. starts easily but will not stay running without throttling up to ~1500 - 2000 rpm. cleaned carbs, found 4 #37 orifices in intermediate ports and 3 #33 &1 #26 in idle ports. i believe the 37 go in idle and 33 in intermediate. switched as such. air screw initial setting @ 2 1/2 turns out. replaced plugs and wires. attempted to check timing. apears to be ~ 8atdc. in water runs ok but does not idle long. at higher rpm planes out but has a slight miss occassionally. compression all within ~20% of each other if i remember at ~ 130 psi.
i am starting to runout of ideas.......any suggestions please and thanks in advance.
