Hi and welcome to the forum. You'll find a lot of good people here with a lot of good information.

My advise is to stay with oil injection, its reliable, much more efficient, and cheaper to use than premix. Your compression is way high, a factory fresh engine is 150. Was your engine just overhauled or have the top end redone? I would check it again with a known calibrated compression gauge. If it's still high you probably have a problem with the squish area.

Check the compression and repost.
