Re: 2-stroke to 4-stroke converts
There should be a hint of blue smoke on initial start up, but almost nothing visable while running. Do you think it's smoking more than it should? Post a video. if there is a question, get with the mechanic to see if the oil injection pump is operating properly. After 12 years, it's possible that's it's about to give up. When they go, it's usually fast and you have nothing to show but a burnt engine. A lot of boaters, jet skiers, etc block off the injection pump and go with premix. It's a bit more of a hassle, but you know you're constantly getting the proper amount of lube in with the fuel. Not too much or too little.
BTW, I had a 1996 Merc 150 Saltwater Series which was 2-stroke/carb. Smoked like crazy until I replaced the oil injection pump. Slight burp at cold start and never a bit more the rest of the day. I also had a 2004 Johnson 150 2-stroke/carb which never smoked at all. I used to always wonder if the oil injector worked because it never smoked, but the oil level would decrease so I knew it was tuned properly.
Get your engine checked before blaming your neighbor for being an old codger. Or, he might have respiratory problems and he thinks you are trying to kill him!!
