Older Jiffy model 30 fuel issue

[anonamus]

 I recently bought an older model 30 Jiffy (1982) 9 inch cut auger. The thing will start up and run great but, but while cutting it will cut thru 6 or 7 inches of ice and then just run out of fuel, I can let off the throttle and let it idle for a bit and then start cutting again only to have it die out again after it cuts a few inches. What would be the trouble??  Thanks for any and all replies..

Gotta clean the carb dude.

Cleaning the carb won't hurt, but its most likely the high idle (the right/outside) screw on carb, needs to be adjusted.  This is very common with jiffys.  If that don't work you likely need a carb kit as the diaphram is likely shot.

Check the gas cap and be sure the little vent screw on top is actually providing adequate vent when it's open.  I had this problem a couple of times.  Buy a new cap (plastic) they are great and they do not leak.

While some already brought up this ?, I was wondering if anyone knows how to take the carb apart.

I already replaced the needle + seat and diaphram, replaced the spark plug, and tuned both low and high idle, but my auger will run for about 3 seconds (while cutting), then act like its going to quit, if i prime it, I can go for 3 or 4 more seconds. Last year it ran like a champ, started first pull, and ran perfrect both idle, and during cutting. So i imagine I need to clean it.

If it starts and runs great and then dies as you explained, the fuel inlet or fuel filter is plugged.

I think there is a small rubber diaphram in those carbs that as they age, they get a pinhole or tear in them. That would cause the symptoms you describe.

I also noticed that when it is running gas will kind of squirt out of the gas cap vent. Would this be  a sign of a bad diaphram or just a bad cap?

With the new plastic cap, I do not get any gasoline spillage.
Pretty soon my Gator will be here and then the gasoline can stay at home.

Most of the stuff was covered ,But,if the primer tube going to the carb, if it has a air leak.it will do that plus, it's running REAL lean,and it's not good for the motor.If you re-built the card you should soak the diaphram in mix gas for about 10-15 mins before you install it.It's not good to install in dry.Spaying it with DW-40 works too.Closest screw to the motor should be 3/4 of a turn out,next one 1 1/2 half to start.Hope this helps.I have been working on them for years and These are a few things that work for me.

 thanks for all the helpful info. I have a carb kit on order and hope to have it up and running better in a few days..
