Been working on this engine throughout the winter. It has been fully rebuilt. I started it the first time yesterday and it ran great. I ran it at 1500 RPMS for about 30mins to run in the cam and called it a night.
Today I started it and it still runs great but now anything over 2400 RPMs and it starts running rough. I checked my timing and it was set at 8* and it seems to be getting plenty of fuel. I changed my points and plugs during the rebuild and set everything to spec.
This engine was running great before i done my stringers transom and deck. The first time out it sound different so i pulled it again. I found low compression numbers and #4 with rust on the walls and destroyed valves. It was all original circa 1981 so not bad for the age. Also my cam gear was stripped and chipped in places. I was the fiber type gear.
I had rebuilt the carb prior to the rebuild due to an acceleration problem. It performed well after.
The engine is not in the boat, I made a test stand to run it to make sure all the bugs are out before I install it. So there is no load on the engine while running. Also the ignition is hooked up pretty basic. I have a gauge panel and wired directly to the senders. Ignition is on switched power to the coil with a resistor in line. One more thing i noticed is that my distributor body gets really hot after about 15mins. I don't recall if it used to do that or not.
Anyways i think it's an issue with my timing or ignition just haven't figured it out yet.
Thanks,
Jeff
