~I recently purchased a 1986 50hp Force engine. and Mon Arc boat. Bottom line I can't get the motor running. Im not extremely adept with mechanics but I know some basics. If I have good instructions I can get by. I'll tell you what I've experienced so far with the motor. The plugs have a really strong blue arc. When I was first cranking it, it was flooding badly. So I removed the bowl from the carb and checked the float. It was moving freely.( used a fair amount of carb cleaner as well) Put the bowl back on and tried starting again. The flooding subsided. From there I tried starting the engine and it " fired" several times but still would not run. After several attempts it flooded. Which I'm assuming is normal. I let it sit for a good amount of time. This time I tried some engine starter and still no good. I had the motor in a large tub of water and after cranking it and having it fire multiple times there was some black and silver crud floating in it. Not a huge amount. But there was some. I hope I was able to give enough information to get some trouble shooting. I got the boat and motor for a cheap price and Im trying to avoid spending several hundred dollars at a mechanic. Any help will be greatly appreciated. If pics of anything will help I can get them. ( Side note. The motor looks really clean and in good shape.
