zdz super 80, need ideas
so, it sat on the shelf awhile. put on a brand new walbro carb, bought new high test gas, mixed 40-1 with penziol. set the needles to 2 turns open and did the 5-5-1 starting .started right up and idles smoothly. however it will not run at high speed. no matter where I put the needles, including falling out open it will not run at high speed,.but it will idle all day with no quiting. if I put the choke 1/2 closed than it will run at full throttle.open the choke, it sounds like it goes lean and dies any ideas ?, I,m at the end of my rope.
