rebuild 13-B, have rebuilt, or buy reman?

generally speaking, you're right. it doesn't much matter. a rebuild is the bottomline if either turns out to be the case. however, there are one or two things it could be that wouldn't mean a rebuild. for example, if you went overboard with premix or something.

in addition to the information already given to you, you can also see which one of the two you have to refill frequently.

Thanks for the tip. I did measure the amt. of oil sent to the carb from the oil metering pump and it was within specs, but am going to try by-passing it and just add oil to the gas to see what that does.
The smoke did start just after an oil change so, I thought that I put too much oil in the crankcsase, but it was the correct amount. I will keep working on this as I don't know where or who can get me a replacement engine of this vintage (74-75)
