[QUOTE="thudpucker, post: 304129, member: 1422"] "What I'd do!" :mrgreen: Let it idle for awhile, pull the Plugs and see if one or both are wet. That would tell you the Carb is letting too much fuel in. So the Main jet is not working at idle. The the smaller Idle jet that may be too large or the Float Bowl might be set just a tad hi, letting too much fuel through. The Needle valve may be leaking as well. You may have too much fuel pump pressure for that old Needle valve and seat. The Points (under the Flywheel) have something to do with timing. That will cause Spitting as well. I wish you luck. I have an old 5.5 Evinrude I want to convert. So stick with me, as I may need your help! =D> [/QUOTE]
