I have a DRPower estate trimmer (DRTrimmer) with a Briggs and Stratton 625E engine.
According to my wife, it was running--threw off the mow ball (I have to replace them once a season generally), and then she shut it down.
Now it will not start.
Using electric start, it would never seem to catch, but would backfire a couple of times.
I pull the plug, hold my finger over the whole and crank with electric start and I get zero compresson. I know that some of these engines have a compression-release system to make starting easier, but there is absolutely zero compression.
I pulled the head. Valves and piston are oscillating correctly but I cannot tell if the valves are fully seating, nor can I tell if the piston rings are good.
I think I have a dead engine ...any comments??????????
