Hi, I recently purchased a 2006 DF115 for a good price but in non-running condition. I’ve tested compression and it’s zero on all cylinders. I know the PO said the guy that sold it to him said it died one day and it ended up sitting for 3 years or so.

I believe valves are maybe stuck open? If so what’s the best plan of attack? I haven’t tried to start it, I’ve just sprayed fogging oil and Seafoam Deep Creep in the cylinders and have been working pistons back and forth. That doesn’t seem to be working. I haven’t tried soaking with motor tilted up yet though. Should I try that and is there a stronger solvent that’d work better?

Thanks!
