Can't offer you a solution but you must stop using starting fluid. Way too easy to wash down the cylinder walls or much worse blow the top out of a piston. Just use fresh gas in small quantities down the carb throat. As a SWAG I think your timing is off somewhere. Even the best mechanics make a mistake once in a while. You'll figure it out.🛠
