Upper transfer angles

[Keith Gandy]

I think that's right. It also flows right behind the exhaust so it's partially wasted and partially filling. I think it helps keep the exhaust flowing out more completely than opening the intake side first to cause a swirl which will mix the exhaust up more.

So are we opening the secondary on the exhaust side a few °s first will have almost the same effect as fingers?

I think so. I need to try more and actually have time to run a saw more than just a tank to make sure it's good to go home. I have an extra 460 cylinder I found. Need to mess around with it a little more.

Well the 460 im doin now is in that fashion from 120 to 118

If you port 3 or 4 saws a week it's a job just putting a tank of fuel through all of them,plus trying to find wood to cut. Most everything around me is cut up now I gotta have wood delivered just to run saws in. I try to just run saws on Friday and Saturday.
