I should say this is a Pond Block with an 1/8” block plate that came with the McLeod SSP clutch. My engine builder, an FE specialist, measured up another FE and told me the gap between back of flywheel and BP was not .55” like mine but similar at .48”. My flywheel M6375 N427 or that’s what is said on the box, is flat across the back, wheareas the one he measured had a .08” negative recess or step, which explains the difference. I can’t understand the variance between these flywheels, yet no declaration in in the spec.
As I said I now have 1/4” fresh air between the TOB and the clutch fingers, which seems okay, to me. I can mill 1/16” off the front of the PM Mini Starter and I’ll have full engagement. I prefer that to removing material from the flywheel and risking any run out, and potential failure.
If I was starting again, I’d ask SCAT to simply reduce the thickness of the crank flange by about 3/16”.
Also the McLeod plastic alignment thing did not align my clutch, despite two attempts. In the end used the TKO itself with the BH off.
I’m also considering taking out the 4” transmission crossmember and moving it back 2”, so I can get the trans in using the conventional mount, without tipping the motor. I intend to run an underfloor system.
