I have a Noma Snowking snow blower model E278-4000. When the item was shipped from the factory, a “Klik Pin” was installed in the innermost hole in the left tire hub. The manual instructs the owner to remove the pin from this hole and put it in the outer most hole in the axle to allow easier mobility. By doing this, the drive train goes form posi to single wheel drive. The manual does not give any instruction how to reinstall the pin into the original hole. I have tried to reinstall the pin in the innermost hole, but the thru hole is no longer visible. I have held the right wheel stationary and rotated the left wheel, but did not see where the thru hole is in the bearing or the axle. Has anyone been able to reinsert this “Klik Pin” back into the innermost hole after removing it? Thank you.

I have a 10hp Tecumseh Snow King snow blower engine that surges. Instead of rebuilding the carb, I found you can order a new one (Oregon brand) for about $25 on Amazon. So I did that and installed it. Still surges, although it's slightly better. Also, I held the linkage still between the governor and carb and it still surged, so that should rule out the governor linkage as a problem, I believe. Gas is only a month old and was treated with Stabil when I first got it, so that should rule that out. What else could be causing it to surge? Could the vacuum tube that goes to the carb be causing that if it's too loose on that little inlet on the carb? It stays on there snugly but the tube is a bit expanded where it connects on the carb. Anything else I should check?
