The carbs on those NH843's are junk. It will likely not run very well.

For reference here is what I leave between the ports. The photo was taken before port beveling.

It appears that the transfers have been raised less than what was cut from the squish band as well as the terrible grinding on the transfer port divider.

I have it back. I did some updates to it while I had it apart and it put up some impressive numbers on Joes dyno before eating another big end rod bearing.

They take a lot of grinding to be even that good.

That's the AM 395 big bore cylinder fighting it. The OEM cylinder ones ran out a lot further, the BB had more lower end grunt (~10.4hp at 8k!).

Don't you have a few 064's I tickled too?

The 37" cannon bar I have is 119DL.

That lathe might be a little overkill to cut squish bands on.

Lets see the chamber side!

Fixing the plug threads.

I can help with that!

Idle air bleed screw. It's essentially the same as opening up the butterfly a little. It forces the computer to richen up the idle mixture to maintain the target idle RPM which will help with the off idle stumble.

They make XL tool holders that will hold 5/8" tooling in the AXA size...

M10x1.0 helicoil is the best option. They really work well for that small thread pitch and the outer diameter of the repair coil is less than the sealing crush washer of the decomp valve.
