Hey guys,
I'm tryin to sort out this little motor. My dad gave it to me after deciding he wasn't going to use it as a backup motor for his fishing boat. Its history is unknown, but it seems in good overall shape. Problem is when I start it, it seems like it has a fuel starvation issue. It starts great, and idles fine, but if I open the throttle too fast, it dies. I took the carb apart and cleaned it. Everything looked okay, though there was some salting and old fuel in there at first. It's all been cleaned out now. I checked the compression and got 160psi in both holes. Plugs look okay. When I went to check the timing (non-adjustable), it appeared to be way out of range. For this model, it should be 5BTDC at idle, and it's not even registering with the scale with a timing light. I'm not even sure if it's way advanced, or way retarted. The scale has numbers 30-0-10 reading left to right on the flywheel. The needle points to somewhere past the 10, like maybe where 20 would be if it were written in. I tried changing the rpm but the timing doesn't change. Can anyone comment on that? Is it normal?
I also have a question on how to read RPM on this sucker. It is setup for a remote control, but I don't have one. My timing light has a tach function, but at idle, it claims I'm doing 1700RPM. I thought these ran closer to 800. I couldn't adjust the idle stop screw to get me to 800, and past 1000 it stalled altogether. I have a voltmeter that has a HZ measuring function, but I don't know how to use it. Any help here would also be appreciated.
