I've got a DD head on a 46fx but haven't started it all summer. Now I've been trying to and can't. The fuel was sitting all sealed up. Does the fuel in the engine/lines gunk up and need to be flushed out? It seems that I get a second of the engine running then immediately dies, and this is after priming with a few drops right into the carb. I already used alcohol to rinse out the engine by turning the engine over and draining. Anything I'm missing or should be doing?
thanks

on, does fuel flow when you choke it with the throttle wide open, there may be some partly congealed castor in the fuel line.

Get some Tygon tubing for gasoline at your local hardware store so you can see if the fuel is moving through it. Set your compression so it flips about like a glow engine. Set your needle about a half turn in from where you would set it for glow. Suck fuel up to the carb and hit it with your starter. It should run well enough that you can adjust it to run better-maybe it will be undercompressed and too rich. Diesels flood much easier than glow engines and won't start very well when flooded. Some of the older diesels had a drain on the crankcase so you could clear a flood.

Go with the advice of the last 2 posts from hobbsy and jim
Also pull off the pressure line on the muffler and the line at the carb. blow on the pressure line fuel should flow out the carb line
go to the hardware store and get an eklund T handle that fits the compression screw I think 3/16 it is 7 inchs long and makes setting the
compression fast without messing with a little allen wrench ( also keep your hand safely above the prop) If it runs on a prime
you also may have excess fuel that will raise the compression till it burns off, to check crank the screw in a half turn (after making sure you have fuel in the line) let it warm up for 30 or 45 seconds then adjust out till you get the typical diesel miss then adjust in till it goes away adjust your needle for best speed,then try increasing compression a bit and leaning if it sags wrong way you will not get a final
till it is up to temp which may take a minute or so
