So Boyz feast us eyes on this. Max originally worked in this derby metra kit head for me but lost access to his machine shop. Anyway Nate the great did this for me and naturally it's innovative. So that's a one way bearing he installed in the clutch so obviating the need for a decompression. Plus the head wasn't machined art the way to the Athena 47.6 width. He tigged dat decomp to oblivion before reshaping the head on his lathe.
Yea I want to one day be able to do stuff like this. This is exquisite as is cheeta 's pull stsrts. This one way valve should spin the crank forward and otherwise disengage. Definitely worth a trial!!! I gotta get to work on this stuff but I swore I would do those vespa engines first.
