Pyro Just Came In, Need Help Turning Fuel Up...

[monkeyfist]

Pyro just came in. I have searched and found info on turning the juice up on these engines but my pump looks diffrent from any that I have seen pictures of. Its a whistler engine. If anyone has any info on this it would be greatly appreciated. I will post some pictures of the pump later.

Soon. The war department wants me to go with her to search for a new dining room table. Then Ill head to the shop and get some images.

Probably should have sent photos with the first post. And there are all kinds of threads on turning the fuel up on a Deuce.

Mail lady just dropped off the pyro and I got trigger happy. All of the threads I have found the pumps are not like mine.

Just do some searching there should be threads for your injection pump also.

Your pump might not have an FDC. Just remove the four bolts that hold down the cover where the FDC would be and you will see the main fuel adjustment. It should look like a bridge with a jum nut on one side then bridge then jam nut. Same thing loosen jam nut inner nut clockwise what you want then tighten outer jam nut. Pic is of FDC.

how far out are your threads in that pic? i know each truck is different just wondering. thanks kyle

The exposed threads with two nuts on it is what he is talking about down near the pump housing. Yours have this? It probablyis under a sheet metal cover that is safety wired on. That cover sure does rattle sometimes sitting in my glove box.

Thats what mine looks like. The ones I was able to find didnt have that FDC thing on top of the cover. Didnt know if that would affect adjustment. Gonna go pull it all apart in an hour or so and get the pyro on. Thanks Floridianson!!

Mine looks just like the one he had in the picture. So Im guessing its the same stuff going on under that cover no matter it has the FDC or not?

 

[Floridianson]

No the one in the pic has FDC and the small tin cover is allready removed and the two jam nut can be seen in the pic faceing forward. If you do not have a FDC then there will be a cover where the whole FDC is and by removing cover you would see bridge and main fuel control.

Red line twin nuts main fuel adjustment on pump with FDC and tin cover removed.

TIN COVERS......Ha Ha Ha.... insert funny smiley here.
Hope you get it figured out. Hows the pyro coming? Thought there would be more questions about that! Install the pyro then play with the fuel! That's the way we almost always do it.

results?

what kind of performance increase did you get?

 

[m16ty]

You'll get a pretty good power increase. Almost like a completely different truck. DO NOT do this without a pyro though. You can melt the engine down pretty easy if you don't watch your EGT.

Ok so reading here let me see if I got this right

To turn up fuel---> remove safety cover ---> loosen outside nut ---> turn inside nut CLOCKWISE ---> retighten outside nut ---> replace cover if you want to

and never do the above steps without monitoring your EGT's, etc, etc



I also sorta remember reading somewhere only turn the fuel up 1 flat ( 1/6 ) turn at a time, is that pretty sound advice??

You got it.
Just make sure you don't let the rod turn. IMO one flat is a little conservative. I don't recall how much I turned mine but it was a pretty good bit (at least a whole turn). I just turned it some, drove it a while, monitored EGT, and went from there. Seems every truck is different and I think mine was in a de-tuned state when I got it so it took a pretty good bit of adjustment to get the max.
