Bonus content, clutch drum was heavily grooved and was almost mimicking a hanging idle...it was just getting stuck engaged. It really needs a new drum, but this is the cheese-ball and el cheapo way to address the issue...but it works lol:
All done, impressed with the results. This has a tapered edge on the piston and tapered squish band. On the negative side, it has some free-porting on the exhaust. Next iteration will be with a 064 piston. I should be able to turn that into a domed piston and solve any free-porting issues.
Next project showed up last night. Not a full build, owner just wants it to "run better." I'm thinking timing advance and muffler mod.
