14:1 on a trail engine? and 112 octane fuel to boot(by the way, what brand fuel are you running?)   you will have to richen it up a little, just keep checking the plugs and piston wash.  If you plan on doing anymore mods(one thing leads to another   you should look into getting something to monitor EGT's.  It is hard to burn down an engine on race fuel, but it can be done.   anyway, make sure you take down a few doo's with your cat
