I have a older model # 30 jiffy ice auger and i can not seem to keep it running consistanly. I was wandering what the carburator adjustments are. The low idle screw and the high idle screw where do I start for as how many turns out for each one. Thanks Randy

Hello Randy. I can talk you through making adjustments to your Jiffy ice auger engine.
1. Read through the whole list before you start adjusting.
2. Close both jets GENTLY
3. Open the Low speed 1/4 turn
4. Open high speed jet 1 1/4 turn 5. Start engine.
6. Adjust low speed until idling smoothly.
7. Open her up wide open.
8. Adjust High speed until engine transitions smoothly from idle to high speed without bogging.
9. Shut engine off. Let it cool.
10. Once engine is cold. Fire it up and let it idle for 30 secs. Open it up wide open again. Adjust if necassary.

NOTE 1: The trick with the Jiffy's is to tune them during cold (ice fishing) weather.
NOTE 2: Low speed screw,the one on the left.
NOTE 3: High speed on the right.
Good luck ice fishing! Regards, Joe

Adjust while at full power, cutting threw ice. Best way to get it right!
