Query: Some poor points

The engine is very difficult to start. It takes two men and a boy to pull the starter rope. No shut off on the gas. Important for winter storage, engine should be run out of gas. After third useage, the engine died--no spark. Troy does not stand by their entire product, the engine is under a Briggs warranty. When I called Briggs, the rep seemed to have limited knowledge concerning the engine. After a listening to elevator music for a long time, finally found out that I needed to get the engine to a dealer. Now of course the unit is very heavy, so if you live a long distance from a service center the shipping costs would be extreme; therefore, I am going to tear the engine apart and try to fix it myself. Wish me luck.
