Need help again with this old crossflow outboard. I am getting an occasional pop from the exhaust only below 1500 rpm with a puff of smoke. Runs great at WOT never skips a beat. The pop only started after I got the O/B back from a powerhead repair. Here's what has been done so far.
New piston rings, replaced one piston due to broken ring. Compression all above 120psi
Carbs cleaned and carb repair kits installed (no idle mixture adj. on these carbs)
New stator, power pack and reg/rect.
New fuel pump, VRO removed
All new fuel line and primer bulb
Checked idle timing 4 deg. TDC
Checked linkage and made sure butterfly valves are closed at idle. linkage timing is set correctly.
The spark plugs are slightly wet but not fouling. I have not checked the primer solenoid for leaks yet. Any ideas on what else to check? Thanks.
