At low speed it chugs. At first, I thought it was slipping in the trans but it is not. At idle and anything higher than low, it is fine. It might be smoking a little more than it should at idle. Where should i start?

Compression is at 100-105 at each cylinder (not quite running temp), good spark, good fuel. What is next? Is that low for compression?

I am used to seeing compression near 120 in other motors is this where I should be for this one?
