Outlaw with webra .36 problems
We need some help. My friend and I over the winter built extreme flight outlaws and being as O.S. dosent make the .32 any more we decided to go with Webra .36. We used the mouse can muffler instructions found elsewhere on rc universe. Mine runs pretty good but the high speed needle is only 3/4 of a turn out my friend had to put a new motor on his cuz his first one was junk. We were breaking it in today and about the fourth tank of fuel we thought we should start bringing up the rpm. It would stumble and die above 1/2 throtle so I pulled the pressure line of the muffler and it would advance to full throtle nicley then slow down a few hundred rpm. We put a restriction in the pressure line and did the same thing (1/2 throttle and die) pull the pressure line off and would run good. The pressure nipple is just after the bend in the header any one have any ideas on this.
