I finally was able to get around to degree wheeling this little engine. And with two 3 thou spacers made from coke can aluminum I was able to come up with these numbers.
intake rotor open 212
intake rotor close 61
transfers 128
exhaust 184
blowdown 28
squish 7 thou
I have ran 3 tanks on the bench and I switched to the supertigre .18 carburetor because it was 7mm and was larger than stock carb. It seems to run real good.
Also trying the ops pipe with a 1/4 stinger to the high point inside running it at 71/4 inches to start on length. I will have to try a few pipes on the water I have about 5 to try so far but it looks to be a good engine . The numbers are pretty good for no grinding just raising the sleeve so I am pretty happy about that. I will also have to try to machine the head down to around 4 thou once it breaks in . Let me know your thoughts on the numbers. and any changes you think would make it better still.
Thanks Dave
