One of the most common mistakes I see people make when rebuilding small engines is incorrect installation of the crankshaft oil seals. This mistake will eventually lead to a destroyed 2 stroke engine every time!
In this video I show the correct method on how to install 2 stroke oil seals, what tools you’ll need (you’ll likely already have at home!) and the pitfalls you must avoid making to install oil seals correctly. It doesn’t matter if you are repairing a Honda Leafblower or Stihl chainsaw, a husqvarna lawn mower or echo weed eater; regardless of what small engine you’re repairing, the process is the same every time!
