mifree 1 #1 Posted May 6, 2018 I have a new to me 520-H. After about 4 hours operation at normal mowing I noticed a small amount of oil running down the cowling under the vacuum fuel pump. The power gauge works normally and no indicator lights are on Tractor starts easy and runs smoothly full throttle or at idle. Any ideas on what is going on.
