Mike; Hi, I have the 3.5 hp jiffy auger also not many at all around anymore! Rare to see one on the ice anymore. The biggest engine Jiffy ever used! Kinda like me at 71 years. I also have had problems with mine. Engine is just fine and I think it will last forever. I’ve had it many years bought it new. I took it in to a (Jiffy guru). I Use non-oxy with a 50/1 mix. I’m sure 40/1 is o.k. also.
The (carb jet settings were my problem). The one on the left is suppose to be out 1 1/8 turns. The one on the right is from 3/4 to 1 turn open. After that it has run really great! I remember adjusting them long ago when I should have (not done). It just needs to be always warmed up good before punching holes. My spring is in the hole farthest from the block, fyi. I love starting it and showing the kids how real men used to punch holes!! Tom Edberg
