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

Hello all.  I picked up another snowblower at the beginning of this season.  It is a Ariens 7hp 30" cut w/ the H70 engine.  I had a hard time pull starting it.  It would pull nice and smooth, and then very hard like binding.  I could pull up, and if it binded, I would lift the maching right off of the ground pulling the cord (and destroying my shoulder).  I bought an electric start, but it just engages and then gets stuck and trips out my 2000 watt generator.  I could start my 5 hp Ariens off the generator and also a 750 watt inverter hooked up to the car battery.  BTW, I have no electricity in the garage I rent, so that is why the generator comes into play. 

For the hard pulling, any ideas?  Once it is running, it runs great.  I will probably opt for a replacement intek from small engine warehouse if it is something major, but I hate to do that if it is something silly.

You guys seem to have quite an information database going on here, so I figured I would ask.  Thanks,

Check your exhaust valve clearance. (.008)
Excessive clearance on older engines will not allow the decompression system too operate properly.

How does the engine turn over using the pull start with the spark plug in but the spark plug wire off?  If it pulls over fairly evenly with no sudden stops with the plug wire off, your timing might be off a bit causing the engine to fire too early.   Try turning it over using the pull start with the plug wire off and let us know how it goes.
