Engine flywheel magneto screw repair

[ibrahim123]

My uncle was trying to unscrew that big screw pulle (or whatever its called) which holds the flywheel magneto of my yamaha engine and he didnt do a very good job. They screw threads are now messed up and i have to get it fixed now. I took it to the mechanic and he checked what thread ring gauge is needed using a thread gauge and he told me that the size is 19G. Apparently we dont have that in this country so im going to haveto order it from outside. Anyone got any site or know somoene who sells this type of ring gauge? Thanks

Maybe post some pics of the messed up part so that we can see what is needed. If you can maybe find a part number, and give the full make and model of the engine, I can see if I could maybe find one here for you. I am not too sure what the postage would be, but its worth a try. I am in South Africa

2 Problems.
A ring gauge is for measurement and not repair. Do you mean a die?
I never heard of 19G as a thread size. It is a wire gauge size.
