Re: smoke smell
A couple things come to mind. I don't want you to overlook a more serious issue, but here are some things you should expect to encounter from time to time.
First, when cranking, if you let off the starter too quickly, the engine fire once and stop with pressure in the cylinders. Also, when this happens you may see whisps of fuel vapors coming from the air intake. It seems like once it happens, the engine is difficult to recrank. The engine turns over a little more slowly and takes a second or three to fire and run. But once it is running all is well. If this sounds like your problem, I wouldn't worry too much about it.
Second, I ran over a plastic grocery bag while driving down the hiway one day. Dang thing stuck all over my exhaust system. I didn't see smoke, but it smelled like burning plastic for weeks.
