Small Engines (Lawn Mowers, etc.): Bolen 2 stage snow thrower 5HP, carburetor jets, snow thrower

Question
I am new at this, my snow blower will not start unless I pull out the spark plug and spray some quick start into it. It will only run for 10 minutes, then stop. It is very hard to start. Any ideas and pictures to show me what to do and what it looks like. Have a BLESS week, thanks....MIKE....  

Answer
 Hello Mike:

 It Sounds like the Compression is Low. With Low Compression the Engine Doesn't have the Required Vacuum to Pull the Gas Through the Carburetor Jets. This can be Caused by Burnt Valves, Valve Lash Out of Adjustment, Worn Rings or a Worn Block. When the Mower has Run the 10min and is Quiting is there a Power Loss? Hope this Helps. I am here if you Require more Assistance. Thanks.

 Good Luck

 Respectfully

 John
