did some porting today:
yeah, that looks pretty sweet. Those secondary runners are massive. All you used was a wire wheel on a dremel to get it smooth? I used some sanding wheels on mine and it didnt come out nearly that well. Also, did you use templates or is this your own creation?

i have a hard time believing an apex seal will catch on the opening edge of the exhaust port... the closing edge, definitely understandable... but the opening edge?

I have tested for spark, fuel, compression, timing, and then some and still cannot find out what is wrong. can you please help me out with some suggestions?

I can't wait to do some serious porting on my spare housings. I have 2 engines laying in the shop to tear down and reassemble as a running engine.
I am no expert on what is good/bad for porting.......but I like what I saw in your pics. Good job!
