Because that would mean pulling off the flywheel a second time. You are already doing the operation to get to the ignition....why do it twice? He needs to know how to set up and check points also. No better time to learn than now IMO.And that could also be part of his problem....Timing could be off a long ways.It is clear that no one has been inside that flywheel for years. I really agree with you on that carb hole blocking though. Try some silicone in it to see if that helps at least. That way you could dig it back out if it screws something up.
