I'll preface by saying that I've done alot of work on outboard motors, but very little on what I'm dealing with here. I have a used Intek plus OHV motor that I replaced my previous with. (same model) Tried to start it and it acted like it wasn't getting fuel. I swapped out the carb with my old one and it ran for about 10 minutes and just died. Let it sit a while and tried to start. After several tries, it ran for about 10 seconds and threw lots of white smoke. Shut her down. Found fuel in the oil. So, old carb throwing too much fuel. Put the old one back on. Drained oil. Put fresh oil. Started her up. Ran for about one minute with a little white smoke. (expected that) Shut her off. Will not start again. Here is the question: What adjustment do I need to make to this carb and pointers on how it's done. Iv'e taken a look at the carb and it looks a little alien compared to what I'm used to with outboards. Thanks.
