Anyone know where I can find an online engine diagram of a Jiffy Model 30? Gonna be in the 20s here this weekend, so I might as well get the old Jiffy tuned up.

Thanks.

Carb adjustments for Jiffy model 30 engine.

pop the red caps off.

Close both jets GENTLY

Open the Low speed 1/4 turn

Open High speed jet 1 1/4 turn

Start engine.

Adjust low speed until idling smoothly.

Open her up wide open.

Adjust High speed until engine transitions smoothly from idle to high speed without bogging.

Shut engine off. Let it cool.

Once engine is cold. Fire it up and let it idle for 30 secs. Open it up wide open again. Adjust if necassary.

The trick with the Jiffy's is to tune them during cold (ice fishing) weather.

Low speed screw,the one on the left.

High speed on the right.

Thanks - what I was looking for was an exploded view of the carb. Any ideas?

You had posted that a couple years ago and it helped a lot. Thanks for re-posting it. I just can't seem to get it to run right, and I think I need to take the carb apart and clean it out. I just want to make sure I get it back together right. I may just have to do it and pay close attention when I disassemble.

Thanks again to both.

Another trick while adjusting 30's is to put a load on it. If tuning at home you can put the safety cover on the blade and push and push it on the ground.
