Poor man still undecided.   My hearts desire is a   u can do 60           my head says 46    and  your reply is 50\50.<div>
</div><div> No. 1 reason I do not go 46 size, is fuel tank size. My flight time is to short with 14 oz .  let alone 8 oz . Can a 46 U.C.D. fuse handle a larger tank?</div><div>
</div><div>Another question , What is the fuel savings going 4 stroke?</div>
