So it appears to have been hydro locked, so we have been getting the water out of it. it will turn with the spark plugs out of it and blow junk every where, but when we put the plugs back in it tries to turn and makes a metal to metal noise but doesn't crank per se'. I am not convinced the battery is strong enough, I measure about 11.4 ish; have had it on the trickle charger most of the day. for a minute I had it in my mind the coil was bad but then thought I should stop and ask those who know what you all think and what else I should look at and measure. have put new plugs in it. get 2 beeps when the key is in. this machine has had a hard life- was a rental and appears little maintenance was done. thanks for your help.
