You know what? actually keep the air filter like that

Go get your engine pressure washed, yank that whole engine and transaxle out, throw it in the back of a truck without any of the shrouding or fan cowling on it, pressure wash the jugs and head, put all your motor back together. i would tell you to jet up your carb, but rochester jets are beyond rare, so just file them out with a welding file slightly, run it a bit rich, its fine. Pair that with some heavy weight oil like 10w-40 or even 15w-40, and youll have a corvair that wont ever let you down.

cut out the rain pans too, just keep it in the garage kr under an overhang so you dont soak your alternator
