Back in the summer I posted my 1948 Cub, new to me, had stopped running and was backfiring. Then I was having timing issues. I ended up getting a rebuilt magneto and got the tractor running this weekend. However, I am low on power and I am getting a back pop through the air intake. I tried adjusting where the magneto was mounted on the engine block to see if that gave enough of a timing change to make a difference, and it didn't really do much. I am trying to decide if I re-do the timing procedure or, if I have a bigger issue such as a valve problem. Anyone have this before?
