Last summer I bought a '83 Ranger 330v w/Evinrude 140 model #E140TRLCTE long story short wound up #1 cyl. ate a ring.I rebuilt the motor, was bored .030 over all cylinders.Carbs were rebuilt, fuel pump redone,impeller,plugs,wires.motor has always idled poorly but off idle and high speed run pretty good.I did a lot of slow trolling one day watching my graph and noticed engine was running really bad.spark plugs was fuel fouled changed them and run better.but while checking plugs noticed every time plugs are removed after idling all four are nearly dripping wet.I have set pickup timing,idle speed timing at 4 degrees,wot timing at 28 degrees,synchronized and resynchronized ,changed float levels a few times,double checked carb jet sizes at dealer #36 idle air jets,#25 intermediate,#67 high speed.checked choke primer system not leaking any fuel even disconnected for testing .all check valves and ports thru bypass covers are good. strong blue spark at half inch gap all cyl's.compression even 120 psi all 4.the motor idles at about 950 or so on the hose.I am not sure of mechanical history before me except someone had put merc fuel hoses. Sooooo before i try larger idle air jets i called around used parts houses and one said i have wrong bore size carbs!smaller like a 90 hp or 115.can anyone tell me what the carb bore size stamped on the front should say?or suggest anything else to check? thanks
