I have a 1961 D17, series II, gas engine. It has been running fine for the past year since I purchased it. It used to fire up immediately but now is taking more cranking to start. This week the engine has stopped running with or without load. Initially it would happen once or twice an hour but would start back up with a little coaxing of the choke.

Now it won't run more than 90 seconds - give or take a few seconds. I thought it might be a fuel line/tank issue so I disconnected the fuel line and ran a test of draining 1 gallon in under 10 minutes - fine. I see there is always fuel in the fuel filter. I'm thinking it might be a sticking float but I'm waiting on some gaskets before removing the carb to check. Just wondering if anyone has experienced similar issue and might have some suggestions. Any advise is appreciated.

Could you have something that is sucking down and obstructing the fuel line when it is running?

I would drain the gas tank and remove the sediment bowl. Check the inlet of the sediment bowl. With a flashlight, check the inside of the tank and maybe even flush it with the sediment bowl removed.

If you suspect a stuck float, remove the float bowl drain and see if you get flow. If not, rap the carb bowl with the handle of a screwdriver and see if it starts flowing... that will prove a stuck float valve.

Another thing to do, is grab a spare spark plug, connect it to the igniton coil wire, ground it to the block, and crank the engine. Got spark? if not:

Another thing to try...

Connect a wire from battery to coil... bypassing the ignition switch.... then crank the engine. IF it starts, you've got a bad ignition switch.

If not, and you have no spark, it's either coil, condenser, points, wiring, or...

The point cam and distributor base bushing are really worn.

Remove the distributor cap, pull off the rotor, grab the shaft and wiggle it in every direction. If it moves by any significant direction, you need a distributor rehab.
