It's been running fine and not burning any oil. It was very cold here this morning, about 25 degrees. The engine started fine and I drove the Apache to work. After about 25 miles when the engine was completely warmed up I noticed a puff of smoke---couldn't tell if it was white, blue or gray---coming out of the exhaust pipe when shifting from second into third. I have not noticed this before and am a little concerned. Could it be because of the colder weather? I've driven it all summer without noticing this, but this morning was the coldest weather I have driven it in. There was no visible smoke any other time, just when shifting from second to third. Any thoughts? Thanks.

This way you'll know if the smoking is constant or truly only when you shift from second to third.
Then again if you see smoke shifting second to third, I can't think of any reason why the same wouldn't happen going from first to second. The same thing is happening engine-wise - a sharp decrease in rpms. I'm sure Hotrod Lincoln can give a good diagnosis on this one.

I drove it some more today and it only did it part of the time. Had a little bit of a backfire when starting out from first once, it's not done that before. I'm thinking maybe the carb might be set a bit too rich?

I'll wait for the experts (Hotrod, Tony, Fred T, etc.) to chime in for a better analysis.
