Need tips Tanaka/GEBE clutch bolts.

[rgm1960]

Hello. I have a Tanaka 32cc. I am having difficulty loosening/tightening the clutch bolts due to crankshaft rotation when I turn the wrench. I saw a video where they stuffed a string into the cylinder to block the piston from moving. Is this a safe thing to do? Is there a better way? Thanks in advance.

never had a tanaka, but have used a piece of cotton rope down the spark plug hole to hold valves up while replacing broken valve springs - should work for most engines

what can be safer than using soft squishy rope in the bore? its the proper way of doing it, far superior to my dodgy method of simply jamming screwdrivers into the fins on the flywheel...

the only better way is with a rattle gun that you would have already used if you had one, so stick with the rope
