New to this forum. I hope that I can return the favor on H1 issues with my knowledge. My issue is that on the main tank I get an engine stumble as it may be having a fueling problem. I dropped the main tank and replaced the hose o rings just to eliminate air leaks into the supply line. I don't have any issue with the aux tank. The only thing that I haven't done is check/replace the xfer valve. Maybe it isn't opening correctly/fully to the mail tank supply line. Anyone have or heard of this before?
Thanks again for the help.
