Dennis, I have checked the tank for leaks, no leaks noticed and replaced the supply line and capped vent.

I washed out the tank with acetone first and then alcohol, then fuel.

I have not tried running on pressue from the stock muffler, I'll give that a try hoppfully Sunday.

Thanks again for more brain food, Jerry

Ya know, mabe I'll just will re tink and renew my membership to PAMPA, I learned a damn lot of stuff from the Stunt News and individual members. I appreciate your reply on that post about me quitting. I rember a couple years ago, Brett Buck talked me thru some bad engine runs on my Silver Fox 40 and flying at high altitudes. I think it may be best to renew to help support the news letter, C/L flying and keeping in touch with people like you and Brett and TPerry. Wish I had more flyers in my area, Rusty Brown lives 60 miles North of me, Iv'e met him a few times, great old guy who learned to fly in my home town, Longmont, Colorado about 40 years ago.
