I have a few 2 stroke engines, and i run them all at the same oil mix 40:1 (its the lowest common denominator, and I use cheap 2 stroke oil).
All of the engines work great. BUT one, a small 3hp (or so) snowblower, smokes a lot with it. Its all the same fuel and the other engines done smoke more than a normal 2 cycle. The snowblower was really beat up when I got it, and clearly had gas with huge ammounts of oil in it (not sure if it was 2 cycle oil or not). I have run it for a year or two since i got it. it still smokes a lot. (its a mtd 3/21 with the tecumseh hsk600 I think thats 3hp)
I guess the carb could be out of tune/gummed up.... or maybe the cylinder is really worn out. It still seems to be making tons of power (it never bogs down in snow). I cleaned the plug a year or two ago, I dont recall what it looked like then, the last year or two of service has left the plug looking nearly perfect. I dont have to use it too much, It plows my driveway well. I use it a few times a year and thats it. So i probably wont bother doing too much to it beyond shooting it up with carb cleaner, but was curious.
Thanks
