I could be wrong here, but maybe part of the problem with the new augers, and small motors for that matter I think has to do with the EPA and the motors having to meet the new clean running requirements. They need to run so lean, and after they sit for a summer they don’t get enough fuel. The jets are sealed to keep you from adjusting them.
Bingo. I’ve shared that info here before and actually started to type the reply again before getting distracted. The EPA requires augers pass emissions test at 70 degrees. 70! And we run them at temps as cold as 30 below. Ask any old snowmobiler how he would expect his sled to run if he jetted it at temps 100 degrees warmer than what he would run it in.
Tecumseh got out of the auger engine biz right as the EPA was starting to enforce the new emission regs. Was the Tecumseh a very good engine? Yes it was. It was also a smokey pig that spewed unburned oil and gas into the air.
In my opinion today’s augers are built much, much better than the augers of 10 – 20 years ago. But the emission requirements make riding the fine line between easy starting and protecting the environment a tricky deal. IF you’ve got a newer auger that is jetted “just right” they’re awesome. If not, they can be a pain until serviced.
