Johnsred 625 Piston on the right. Nice piston, but not enough room in the lower transfers to make it work.
Sometimes you can install a bigger boot from another model, but otherwise, there is not much you can do to mod rubber boots.Have question on the intakes with rubber boots. Assume you can open both the boot and the carb some percentage additional x-sectional area from stock.
You need MOTA to answer those questions. :msp_w00t:How much do you really gain by widening an intake port past the percentage x-sectional area gained by opening the boot and carb? Is the theoretical gain based on the x-sectional area change as it approaches the crank case? If you can't really change the carb or boot x-sectional area much, does it make sense to widen the intake much vs. add some intake duration?
Oh, this is good stuff. I am pleased and not at all surprised to see the 036 performing so well. Very curious about the Efco.
Ports all look good and lots of potential there. But the combustion chamber offset to the exhaust side would worry me on detonation if pushing the compression up.
I really am at a loss as to why they would have done that?
Emmissions?That goes against all the theory I've read ?
The engineers must have had something in mind, but what ?

if it was about spark plug location driven by the external packaging covers & other stuff
The 165 cylinder will not bolt on the 156-962 chassis, is that correct?
