[kilro]

Good morning!
Thank you for all your input to my u20 issues.
Just wanted to update,removed engine and trans to check flywheel and clutch pro lemme solved when I bought u20 machining was already done including flywheel. Doing a simple measurement with veneer caliper flywheel thickness was off 70 thousands. Recut and checked balance flywheel, engine now is incredibly smooth. Also took the opportunity to replace starter with reduction starter from Dean would highly recommend. Again thank you again
