Hi all, I am having trouble with my mower hunting at full revs, I have replaced the bearings and seals in the engine and even put a brand new govenor spring on it (it was real hard to start when it was hot and the new seals fixed this right up) but I have been told to drill out the jet to the next size drill up which I have borrowed a drill set to this with so my question is has anybody done this mod and will it fix my problem? Just to clarify the hunting is not that bad but is noticeable and fuel tank and filter have been cleaned and carby has been cleaned out and it has a new fuel cap breather as well.
