...sounds like you're gonna have one hell of a morning too :)
Always a great morning...my wife makes sure I wake up with a smile, every day. Living the dream lmao
I read some... and sometimes it's a joke I cant keep from a constant chuckle while reading. I couldn't take it serious. Funny.
So no one liked the guide profiling tip? Even though it's the safest place to place aside from doing a gasket match. Probably thought I was gassin some more.. Ok haha, well it works. How about when grinding -hold tight and dont lean on it too much. Keep your thumb/finger on the off/on switch.
Spray a 'little' light oil before starting.
Mark an area with dye to better control coverage to not get carried away in over working an area.
Stay off the dog leg side of the short turn, work the straight side short turn to even it with the dogleg side some and contour it from the very highest point off the straight wall, a lip there is good in this case...it will speed and draw more there. Until you hit over 240 cfm the pinch isnt really an issue.
Shorten the guides height 3/8 or so.
Look at a carburetor...those are relative to bowl shape coming off the lower 60/70 angle on the far side..but to a lesser degree.
Just look at 'good heads' with 'proven numbers' and let your imaginations run wild...within that tiny little constricted box aka 'production port' of course..
