    9.5 issues

    Yes crankcase compression is about 65# on Ea cylinder,far as the reed valves I looked at them they all appear to be completely closed I'm not sure exactly what I'm supposed to be looking at, from what I understand they should be closed and no light should come through them correct? Yes I spent...

    69 9.5 Evinrude spuddering/coughing

    Ok was just trying to avoid buying anything extra that I don't have already,have a new plastic float from the carb kit I purchased,the only thing I didn't do was try cleaning the small holes on the throat because there not very accessible, figured I could plug the hole where the plastic core is...

    69 9.5 Evinrude spuddering/coughing

    Didn't use high pressure air,lots of carb cleaner in every orifice tho, never tried to tilt angle,the plastic core plug on the side,best way to remove it,and also does it really need to be replaced or can you just plug it with something else,and out the aluminum cap back in the outside?

    I removed the two Welch plugs on the side of the carb I did not remove the plastic one though I did clean behind the one on the top I wasn't sure about the plastic so I didn't disturb it

    69 9.5 Evinrude spuddering/coughing

    Ok ,but what could the carb issue be, perhaps the low speed chamber is corrupt? What do you suggest find a new /used carburetor? This issue has been driving me nuts!!

    69 9.5 Evinrude spuddering/coughing

    I've cleaned it out two or three times,just to be certain,far as I know it's the original low speed needle,it looks decent but not sure if that makes any difference,just because it looks good?

    69 9.5 Evinrude spuddering/coughing

    Yes seems to have no effect,I'm wondering if my low speed needle is defective?

    69 9.5 Evinrude spuddering/coughing

    I've done all of the above mentioned things,it's made no difference, I've got good spark on both cylinders,fuel pump appears to be working properly,it'll run with choke on but when the choke goes to the off position it spudders then finally dies,the low speed adjustment seems to have no impact...

    69 9.5 Evinrude spuddering/coughing

    Ok I'll look into that,put a new head gasket on it,was running way to warm, tried the thermostat and that didn't work, running hot is now resolved.it ran decent when I first got it,but decided to rebuild the magneto,could,points, condensers wires ,plugs

    69 9.5 Evinrude spuddering/coughing

    Hey y'all I'm trying to figure out why my 9.5 won't run right or idle properly, I've replaced the entire ignition system new wires, plugs coils condensers, carburetor cleaned and rebuilt and it just won't idle properly it coughs or sneezes really bad no matter what I do to the slow speed...
