Jiffy Carb Setting

[folke2000]

A question for those who are more mechanically inclined than myself.

Problem: I have a 2 hp Jiffy auger, and when the auger comes under load while drilling, I have to let off to 1/2 throttle or it quites. Do I adjust the high speed mixture richer or leaner? Do I have to mess with the idle (it seems to idle fine)? Not a huge problem, as I know what the personal temperment of my auger is, but when someone else uses it they struggle. I would just like to get the best out of it.

i had a similar issue with mine. the carb needed to be cleaned out and the gaskets needed to be replaced. starts and runs like a top now.

I had the exact problem and tried messing with the adjustment screws before getting the carb worked on. I backed out the one on the right 1/4 turn at a time then would try to drill a hole. After two 1/4 turns, it worked fine and now drills like a champ.

similiar question, does anybody know where i could get the bolt and nut that holds your shaft and auger together?

If you have a carb that is adjustable, turn the high speed mixture screw out 1/4 turn. This should solve the lean running condition.

If the engine idles good on its own and does not die out, leave the low speed mixture screw alone.

Your carb should be a Walbro carb. The mixture screws are marked with an H and a L for high and low.

Take note. If your engine is stalling out at high speed due to lean fuel conditions, do the adjustments before you run the engine again. If you are not getting enough fuel to run the engine, you also are not getting enough oil mixture to lubricate the engine.

If the 1/4 adjustment does not help the condition, take the auger to a good reputable engine shop. The carb needs to be cleaned and assembled with new pump diphagrams. Minor job for any good shop.

I have a 9" jiffy 3hp stx stealth auger. I have the similar problems sometimes where it will run fine but when I go full speed it will stop or wont cut through the ice and will die off.

a couple days ago, i had the choke or idle swithch on the first turn and it ran better than having the choke/idle off. I want to clean the carb, I am wondering where that part will be or how to clean it out?
