folke2000 Posted December 31, 2002 Share Posted December 31, 2002 Which screw is the high sped idle jet screw on a 2 hp tecumsah (sp?) motor. My auger quits under a load, and after warm up will only drill at full choke. It has fresh gas, with seafoam. Any help is greatly appreciated.Thanks for a great forum.

0 Surface Tension Posted December 31, 2002 Share Posted December 31, 2002 There will be a L and H on the carb body to identify the high and low adjustment screw. In your case turn the High speed out 1/4 turns till it run right. Link to comment Share on other sites More sharing options...
0 Evenflow Posted December 31, 2002 Share Posted December 31, 2002 I have a similar problem, mine won't stay going unless I keep giving it gas in between drilling holes. Should I be turning the L screw 1/4 turns clockwise until it runs better at low speeds? Will this effect how it runs at higher speeds? I don't want to mess the top end up, because it runs great right now when I'm drilling.I wish I knew more about small engines.Evenflow Link to comment Share on other sites More sharing options...
0 Surface Tension Posted December 31, 2002 Share Posted December 31, 2002 Threes 3 adjustments. Idle Speed: which is a set screw on the linkage. This adustment simply sets the RPM's at idle. Low Speed fuel mixture: Its possible to lean this out TO MUCH and then compinsate with the Idle Speed. High Speed fuel mixture: Set this till you get high RPM's at full throttle under a load. Then turn out 1/4 turn, Why? so you arent running to lean.Evenflow, We dont know if your getting to much or not enough gas. Turn your low speed in {clockwise) while counting turns till it just stops, dont over tighten the adjustment needle. Now back it out to where it was. Start the auger and turn out (counterclockwise) 1/4 turns. If you improvement then go back to your starting point and turn in 1/4 turns. Link to comment Share on other sites More sharing options...
0 Evenflow Posted January 7, 2003 Share Posted January 7, 2003 Hey ST,I finally got around to adjusting my my auger and there are only TWO screws, now I'm really confused... There is one for the idle speed, and one that has L and H on opposite sides. Should there be another screw somewhere? Do I have to open the carb body? Or look somewhere else?

0 Surface Tension Posted January 8, 2003 Share Posted January 8, 2003 The only adjustment inside is fuel level. What's the carb name and number. Is your Jiffy a 3 hr.? Link to comment Share on other sites More sharing options...
