My projects list for the wankle Panther:
Remount engine, fit new exhaust pipe intake, cut down outlet to fit, rework hold down straps. Rebuild carb (Tillotson HL, should just need the needle free'd up, hopefully...) remount primer (got stolen for the '86 Panther but I think the one from that sled actually was good), add fuel, fire it up. Tune carb, replace seatback with better spare one.
Can I do that all in a day? Maybe, I think it only took at day to dismount the motor...
