Went out to field today looking to figure out why I was having problems with my ST 3250 with Perry pump carb and VP-30 pump. I got my answer. I fueled up with a tank of Omega "Super T" fuel and followed the instructions to the letter. Engine came to life and ran perfectly after final tweaking. The problem I was having the day earlier was exactly what I suspected. Too much lube in fuel. 12% lube is perfect for the big 3250. Idle/midrange/top end were all crisp with instant transition. I used a FOX R/C Long plug with idlebar. I tried other makes of plug but the good old FOX plug worked the best. Thanks Duke!!!! We miss you! The Omega "Super T" is 12% synthetic/castor lube with 5% nitro. I actually think no nitro would actually be even better. I'm going to mix up some fuel with 12% KLOTZ KL-100 and ZERO nitro and see how this thing runs. I had a great time today. I'm gonna put the cowl and wings on this Goldberg YAK 54 and maiden it on Wednesday. Thumbs up!!! Speedy
