Jiffy

12 posts in this topic

So I have had this Jiffy for 6 years now and I still hate it. The most cold blooded SOB I have ever meet. Its a 3 horse stealth. On a warm day it works pretty good but on a day less than 20 degrees she's a real-------. I have to keep pumping the primer when I am drilling otherwiese she wants to stall. Is there something I can do, besides by a Strike Master or Nills? I mix the gas just like the bottle says but I am thinking of running a little more gas and less oil because it seems like the mixture is too rich.

Maybe someone can chime in here, but isn't priming an indication of a bad diaphragm?

You have the vent on the gas cap open I'm guessing?

Have you tried adjusting the low speed carb screw?

I had the same issues,I had the shop rebuild the carburetor and she runs fine. Could be as simple as a high idle adjustment or the diaphram or jet. Costed me $100 to get er done

Or maybe let it warm up a bit. I have to do that for a min or so.

Few things

Varnish laying in the jets/bow.

Bad diaphram

Oil mixture to rich or heavy

Leak or rotted fuel/ pump line

Just way out of tune

Get a tune up on the unit and it should be fine. We let ours ride in the back of plow trucks and shake the snow off before starting and they always fire up.

Sounds like your stelth is a little fuel starved. Most likley caused by the high speed needle ajustment. Sounds like it needs to be richened a little . This should be done in 1/8 turn incraments counter clockwise until it runs proper.

Thanks for the suggestions. With blizzard setting in tonight I should have plenty of time to play around with it in the garage tommorow. I am not a very good mechanic but I always try to treat my small enigines right. I buy non-ethonal gas, change plugs, use stabile but them small engines always seem to get the best of me.

Gonna hit the ice hard today. I guy would think with this big weather change coming the wally's will jumpen out the hole!!!

I have a Jiffy Model 30 that I'd love to get rid of and get one of the lighter augers, but it's the most reliable auger in the group of guys I fish with. Always starts, always cuts, regardless of the temperature. I think the advice the other guys are giving you is good advice that will take care of your issues. Good luck.

Have you tried adding some seafoam to the fuel. This stuff is a life savor.

I was having a similar problem last yr, my model 30 wouldn't start, and it was the first yr I used it. I was so mad that I wanted to sink it to the bottom of the lake, I even broke the cord, that really made me mad. I took it to the jiffy place in st.cloud, and they replaced the cord and adjusted the idle for me. They told me when they tune them at the factory it at room temp not sub freezing temps where you actually use it. Ever sence then it runs like a champ.

    • Money to be made, and the cold war (you remember the cold war, right?) was the reason we did various things.    Go read about Stalin and his successors to see why we were worried about the Soviet Union.   What we did might or might not have turned out like we hoped but that doesn't change what the situation was.   
    • Dave, your economist wants immigrants to meet requirements like posting a bond or having assets.  Why should they do that when they can just come in with nothing through the porous borders?   Isn't the argument about open borders vrs controlled immigration?   Would the 11 million undocumented have to go back home and post a bond?     If the US through its political process decides to allow immigrants, that's cool.    But that is not what we have now.   Better pick that mike back up.  
    • I'm still trying to figure out why we pushed the coup in Ukraine, other than to cause trouble of course.
    •   Ditto, almost exactly the same. I wouldn't spend a ton of money on decoys if your just starting.
    •   To tell you the truth. I have never cleaned a cottontail ever that didn't have flees all over them in the winter. So I just stop hunting them and went for Snowshoes which are bigger and never found flees on them, oddly?
    •   Seems the hares are down from when I was younger but the cottontails seem plentiful enough. I popped these with a 20 gauge shotgun while grousing
    • I use to go for Snowshoes a lot in the winter with a scoped 22. It was fun sneaking through the pines looking for them. See the little black eye and "bing".  Seems like they just fell off the face of the earth for many years so I just gave up trying for them. I'm sure with the big "Down with Fur" thing and not many taking out as many Fox and Yotes by trapping it really took a hit on the bunnies!  I wrote the DNR back a few years ago and asked them about it and he said: we really don't manage the Rabbits at all. And he gave me the old "Grouse BS". Their just at the bottom of their 10 year cycle!   Seems to always be their answer!
