Deleted the base gasket, took .009 out of the band to come up with .018 squish

Transfers are also staggared. Primaries opening 3 degrees before the secondaries

You cut the squish manually or with a lathe?

Mastermind cut it for me

David, did you raise the lowers slightly? The area in which the charge is directed into the lowers within the CC is very narrow...I've considered removing material there before.

I opened the lowers on the secondary side to match the case. I wanted to keep them tight for velocity

 

[T.Roller]

This picture shows the lowers. One side I hadn't touched at this point and wasn't finished with the other.

Gotcha. Cheater. Lol. He's doing a couple of saws for me too. I'm trying to put together some manual squish cutting tools. Hard to find someone with a lathe around my part of the world.

28 on the primaries and 31 on the secondaries

Are you gonna explore carb options, maybe try a hd 12 or modded zama on it eventually? Or leave the carb alone?
