Think you may have a vacuum leak. a really lean engine will run hot. Stick with working on the things you changed to get it in this condition. The single plane will raise the power band substantially.

Checked the vacuum, its 13 by but shaking alot then I ran it down the street. No power at take off, but its a Damn rocket at 3500 rpm. Parked it, pulled off the vacuum caps at the tree and idled up and quit stumbling at idle. Ran it down the street, now low end just stumbled, caught up and was a rocket at 2700 rpm. I also noticed that the temp was rising pretty fast. I also noticed that the carb was hard to adjust the air to fuel. I ended backing them all the way for the best idle. But all and all it would run alright at idle and then start ****tin itself in gear. Why would it run better with vacuum leaks? Makes no sense
