Hello~
A quick history on the motor; bought a few years back from a guy, it did run but the prop wouldn't turn in either forward or reverse. The engine sat for a while, then I finally had some time this spring to disassemble the lower unit and see what was what. Well, turns out the pinion gear and the forward gear were mush. So, with all new parts I was able to completely rebuild the lower unit and get that back on. I have also installed a new fuel pump and rebuilt both carbs, and new spark plugs too. Any history beyond that, I have no idea. The motor runs very good at low and mid range RPM's, however when I go WOT after a few seconds, it surges for a few seconds then drops RPM's on it's own. If I back the throttle off, to a mid range or low range, the problem goes away until I go WOT again. I have searched the forums here and my best guess is that has something to do with timing? Any thoughts or advise would be greatly appreciated! I do have a video of it, but I couldn't figure how to upload to this site. I could email if that would help.
Thanks,
Chris.
