priming d2 eletric start

Are you sure you don't have some dirt and gunk stunk inside the injectors? I just had to bleed my D4 today and was amazed at the crap that came out.

You are PULLING the throttle open aren't you? Also pulling it hard? Sometimes the linkage gets jammed and takes quite a tug to get the governor over the fuel shutoff detent.

You should be seeing a mosquito choking cloud of white smoke from the exhaust if it's delivering fuel properly. Scant amounts usually mean the rack isn't opening up or there is still air in it. On the ether spray, are you being cautious or liberal with it? It can take a healthy spray to get a combustable amount into one that isn't injecting any fuel to go along with the ether.

Of course you could have had another problem at the same time, but most likely not.

I cannot imagine how your bleeding proceedure has resulted in plugged injectors all of a sudden.

Just to avoid any question that there might still be air trapped in the fuel system, I would go back and bleed the fuel filter tower bleed knob on the front of the filter top cover to ensure there is no air there. Then the injector pump bleeds again and finally the injector lines at the injectors. Then if it still doesn't pop off or at least smoke liberally when you pull the throttle wide open, suspect the rack/governor setting or decompression mechanism.

Your note that the engine is turning over very rapidly might mean the engine is still decompressed for some reason.

and...

Are you sure you are getting a flow of fuel out of each bleeder screw behind each injection pump? Even if there is fuel getting to the injector does not mean all the air is out of the pumps.


These are both common problems

With the engine turning over rapidly I reckon it would be worth checking the decompressor mechanism in case its stuck since its been sitting a while.

If you tried ether and it didnt even try to fire you have decompreession issues I would believe. this would be why you have no white smoke also.

I talked with a member and he gave me some ideas.

first I took the transfer pump check valve spring out and stretched I little and that bought pressure on gauge up, then I took a piece of wire and cleaned out the bleeder holes out on top of the injector pump until I got a real good flow of fuel when I opened them.
then I pressurized the whole fuel tank to 5 lbs with a piece of tube over fuel cap bung.
then bleed fuel tower and injector pump and all the lines. took valve cover off and made sure there is some valve lash on each cylinder.
opened inspection cover on injector pump and made sure fuel throttle rail was moving with throttle. it moves about 5/8 of an inch.

tried cranking it with 2 mins on preheat and still nothing no smoke or popping.

I can turn the motor over by hand fairly easy. like theres not much compression.
how easy should they turn over when there cold?
last time it ran it had plenty of power and didn't smoke much.
I am stumped.
