34deg on methanol

Mini Bike & Go-Kart Parts

Quick question so I was running 38deg timing on my alky predator that is bored to 72mm on stock stroke. Question I keep sheering off the 6deg flywheel key. Would it be ok to run 34deg on alky for now?
did you try lapping the flywheel to the tapered crank first with valve lapping compound. the keyway does not hold the flywheel in place, it only times the engine.
here is a picture of what the crank/tapered end should look like after lapping it and the flywheel should also have a solid gray pattern...:scooter:
Yes always lapped the flywheel and crank when I install new flywheel. Idk if using a electric box start causes it to break overtime. Just wondering if it’s cool or ok to run at 34deg
