Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Snow throwing is new to me and so far I have learned the value of fresh and well mixed gasoline.  Also, I put a new shave plate on it and that helped it quite a bit.  My question at this point is' "is it supposed to be self-propelled?"   When I pull up on the handle the 'blades' contact the surface and propel it along very nicely but the snow clogs much quicker.  When I do not allow the 'blades' to actually touch the surface and propel the unit, it throws much much better, but is very hard to push that way.  I'm sure I probably need new rubber for the blades.  The rubber is about 1 and half inch  on the wearing surface.  Any other tips you can give me would be greatly appreciated, thanks,
