			I the engine is truly out of balance this may sound low tech but if you don't want to re-balance the whole engine you could remove the trans and clutch. Then run the car with just the flywheel. this would take the clutch out of the equation. Then using the bolt holes for the clutch you can add weight to different areas to see if it helps you balance. If you find a combo that works you can take your flywheel and have weights added or removed.
