That's going to be a smooth runner.  The Vanguards are a well balanced engine, especially the small bore variants.

They are real tight in a C-series.

Excited for the mockup of the engine soon.  All the calcs and measurements check out, physical placement is the next step.

I like this diagram in particular. 

It shows me a way to measure my own.  

@jsoluna is it ok if I post this in my own thread?

Absolutely.  Some measurements are easier to the OD of the crank, others are easier to the centerline.  That was just a rough sketch, so the physical references are pretty sloppy.  I plan on redrawing it.

You ain't kidding!   Vanguard red looks good in there though.  Doubt you'd fit a Command twin in there without modifications. Shrouding and form factor in general are bulkier.

The crank shaft center location on a 8 speed is the back side of the PTO loop hole bolted to the frame.  I raised the engine 3/4", here is the base plate on the 312-8.;

I need to look at my Tecumseh plate. I'm hoping to use that. Not sure what it has for a rise height.

Excellent. Thank you.
