Well I had been running OS #8 plugs which are normal sized plugs in an engine that wants to run a long plug like an Mccoy 8. When I put the new plugs in will the compression change be noticable? Easier Starting? More Power? At all noticeable? thanks
The compression should rise slightly and should get a better burn because the plug will stick into the head button correctly. I'm just not sure if you will notice a power difference or not. Will there be a difference I would say yes just not sure if it will be noticeable.
