I recently had my 20 hp 1972 johnson serviced. The repair included a tune up and replacement of all the condensers, plugs. plug wires and pts. I was told pretty much everything below the fly wheel that was electronic was replaced.
First time out it ran great for about 4-5 minutes and then it started sputtering and coughing as you could say. It had a very rough idle. It sounded almost like a 4 wheel when they idle. It was kinda popping and such. I took it by to the guy that had serviced it and he checked it out. He said that he thought I had a leak in my fuel line. He then used his tank and started it up. For the 2-3 minutes that i was standing there watching him it ran like it was brand new. It was really throwing water out of the tank it was sitting in. I went home and replaced the fuel line.
Second time out. It ran great for about a 5 minute idle. Started right up, then once i got out of the trees at the lake I opened it up and went about 2-3 hundred yards and turned around to start fishing. A few minutes later I decided to let the motor Idle while we fished since it had been a few months since it had really ran. It idled perfect and then I shut if off. When it was time to go home. I started it up and it was a really rough idle, when i put itin gear i could not get the rpm's to go up. It would not idle very well and ran like total crap.
When i gothome I put it in a barrel and started tinkering with it. It would start up and run really rough like before. But this time i noticed what seemed to be alot of smoke coming out of it. Alot more than normal.
Tomorrow I am taking it back to the gentleman that worked on it. He has been nothing but kind to me and I am sure he will make it right. I am just searching for opinions on what the cause to this may be.
Thanks,
James
