I posted about a month ago about my Fisherman not pumping any water. The impeller had taken a set and was the problem. Because of the season and other projects I left it apart for awhile, but bought a new impeller and threw it together last week.
When I first got it I cleaned the points with some emery cloth and cleaned the carb, and put in a new fuel line. I had really rich fuel mixed because I wanted plenty of lube for that first start. It was last registered in 01 so it had sat awhile. It started and ran without much work but wouldn't pump water so I didn't run it much.
It fired right up in the barrel of water and pumped water really well. Seemed to run pretty smooth so I let it idle and cycled it through the gears and ran it through the RPM range and called it good. Ran cool and pumped water the whole time. I packed it up and took it to the test pond.
It started without any problems in the pond. I added some fresh gas and a little oil so I'm running a little closer to the 24:1 recommended mix. I've read that since mine is a 64, it should have roller bearings on the crank. Can I run it leaner on modern oil to cut down on smoke and pollution?
Whenever I give it throttle with a load it just kind of chugs and doesn't gain any rpm. Sounds to me like it's not hitting on both cylinders because it will "kick" sideways every once in awhile, like it's got a misfire. It even does it a little when revving without a load. I realize that it's a little small for a 14' tinny but it should still run a lot better than it does.
I am still running the plugs I got with it. When I pulled them they were both wet. I heated them up with a propane torch and stuck them back in but it didn't seem to help. I bought a new pair of J6C plugs to put in it today. The points and coils are original as far as I know. It has great spark when I check it, bright and blue. I bought an inline spark tester today so hopefully I can check each cylinder when it's running to narrow down the problem.
I do have a theory about why it might be fouling the plugs and not running great. The whole time I was running it (probably 30 minutes total, idling, driving, or revving) the sides of the engine stayed cool. Not even hardly warm, and the cooling water that was coming out was cold also. The day I was running it was about 50*, but the water temp is still around 35*. Shouldn't the engine warm up somewhat in that time period? It does have a thermostat that I believe is working. Is it common for them to stick open like on a car? I think if I can get it up to actual operating temperature, it would run a lot better.
