Ok, my 63 10hp sportwin, when its on muffs it revs up great and idles ok, mess with high/low and it smooths out, now switch to lake, or in tank. now engine runs smooth, but full throttle seems like half throttle, its pushing a 12ft alum john boat. I messed w/ high/low. I have spark, all new ign parts ( points, coils, condens, etc.) fuel pump seems like its working, pumps out fuel, So here iam, could it be the timimg bar that rolls over the cam roller? Could that be not adjusted, and how to make correct adjustments? Low is at 1-1/2 low 1/2. good Compression, its weird, it runs really smooth, but only feels like half throttle at full, I seen it do full throttle for like 5 seconds once, and it went back to half. Cleaned carb, new gaskets, no leaks, Any options? Thanks jennyandmike21@gmail.com. email if you would like!!! Thanks:facepalm:
