I bought a used self propelled push mower yesterday . Thought I deserved it . The Amish small engine shop had a decent price on a decent mower and they are quite honest people . Got the dern thing home and proceeded to pull the starter rope until my right arm was ready to fall off and my back started to cave in . No Go . Put fresh gas in it and new plug and ..............no go . Plenty of spark and wet plug and .........no go. Loaded it up back in the truck, took it back, He started it first pull . He said to make sure to have the safety bar all the way pushed down or it may not start . OK I say and thanked him . Took it home and it started but not without several pulls . Went this morning and got a e-z start plug at the store and got it started several pulls later . Shut it off and tried again .........no go . My arm hurts my neck hurts and my back hurts now I no go .
