I am helping my neighbor with his ELS 725. It has been sitting all summer (which adds to the challenge!), and here is what I did:
1. Charged the battery: it cranks fine
2. Verified it has spark
3. Installed new plugs
4. Verified (with my thumb, not a compression gauge) that is has compression
5. Drained the fuel, put in new fuel
6. Changed the fuel filter
I noticed that while the old filter had some old fuel left in in, the new filter would not fill with fuel. Indicates the fuel pump is bad? I ordered a new one to be on the safe side
Regardless of the fuel, I sprayed ether into one cylinder (then replaced the plug of course) and don't get any firing. Indicated something else afoot.
I can get the model# and serial number if needed.
Any ideas where to look next?
