Idle runs nice and smooth at 550 rpm. I may do the bushings anyway.

greg couple of questions? when did this problem start? did you pull the carb and overhaul because of this problem. this could be a timing advance problem in the dist. or is your cam broke on the secondaries not raising the sec. rods out of the holes to give it enough fuel.when it doesn't run as fast as you think it should. does it act like its running out of fuel.give us a run down on how this all started and someone will have the answer to help you fix the problem. dean

greg sorry for the questions i didnt see your post on the sept.25. how did the carb work on the old engine? dean

Hi Dean,

I can't say for sure. I bought my boat in August 2012. Engine failed in September after a couple of miserable outings. Manifolds were bad. I wish I knew then what I know now. It's quite possible the carb was not right then. I did do a rebuild using Cliffs Marine kit. It's running real nice. Since I replaced the motor I've been trying to troubleshoot my WOT problem. Stopped counting the $$$ spent quite some time ago. :-(

It's been better with every step though. I'm just trying to get it right.

Thanks for following up. This is my new favorite forum.
