So I opened up the blunderbuss to take a look at the baffles. Guess what? SOMEONE ALREADY TRIED TO DERESTRICT THE THING! The exit tube is 1/2", which leads me to believe that someone tried to mess with it, but the transfer holes seem to be unchanged. The plan now is to enlarge the transfers to 3/8" and add two 1/4" holes.
I just want to say thanks SO MUCH for all the help, especially Rebel and Mel.
Next step now is to port the stock cylinder, slap a 15.15 on it, and maybe upgrade the variator. :)
