hey fellas,
i can't seem to get my os 91fx to run now. it's on a vectorflight extra 300 66" and the first two flights resulted in dead sticks. it would start just fine, idle well, and throttle up with no problem, but it would not run at more than half throttle for more than 30 seconds so i pulled the tank and discovered a pin hole in the feed line right at the tank. i then cut an inch off the feed line to eliminate the pin hole and put everything back together. now it will start when i prime it but only run for a few seconds and die. i have the needle valve out two turns from fully closed and set the mixture screw to 1 1/4 out. i did turn the mixture in and out 1/2 turn each way but it didn't help. there is a pitts muffler on it but i don't know how that could affect it.

i really apreciate it if anyone could point me in the right direction!

scotty
