Countryboy when you drained the filter, was the engine running? If it was, you most likely got air in the engine. It sounds to me that your Transfer Pump went bye bye.
Here's how to check it.
1, Open the 10mm bleeder screw that is on the fuel line fitting on the side of the cylinder head, above the filter,right under the intake. (Just open it a couple truns since it has a groove in it to relieve air)
2, locate the transfer pump. it looks just like a gas engine fuel pump and it's on the left side of the block above the starter.
3, locate the small lever on the side of the pump- you will use this lever to actually work the pump manually. If the lever seems too easy to move, tap the engine over- the pump may be "on cam". There also is a detent which keeps the lever up, make sure you return the lever to this position when done.
4 Move the lever up/ down to pump the pump. At this time you will see fuel/ bubbles come from the bleeder screw. If the lever still seems limp, or if nothing happens, the pump is likely bad. Continue to do this untill solid fuel is bled.
5 Tighten the bleeder screw- not too tight! and give the lever another pump or two.
This will not get all the air out, but should get you running. Also, this is how I change my fuel filters. I put them on dry and then pump fuel in the right way. Good luck!
