hey wannda, i hardly ever see you on 1stgen any more

okay back to the issue

i rebiut my pump and i can figuar out the problem

when i give it fuel and bring the rpms to anything then let go it takes about 4 seconds to finaly start to deselerate, like its not on and off its on and ........................ off, like it take 6 seconds to go back to idle

any ideas would be apresiated

Sounds like you're on the bleeding edge of a "Run-Away" condition.

Back off the main fuel screw about a half turn.

maby thats all it is, but then im going to have to put the idle screw back in witch seem strange

I've been too busy to keep up with more than one site, I will be back over there before too long.

Yeah it defiantly sounds like the edge of run away. Just back the screw out some and you should be fine.

daking

tomorrow i will find out, with my 205 pump the screw was all the way in and it never ran away, but this 114 pump is running away and it seems like i could of left the sleve on the screw, and it still would of ran away

woundering what kind of boost you see with those twins? any head problems?

My 4BT had this problem, turns out it was the fuel screw in to far. I have no Idea how I managed to turn it in so far but after it was backed out a bit the truck ran fine!

daking

i retorque the head to 125ft and im probaly going to do it again to 140ish
but ive seen 50 pounds twice for about 4 seconds, with 6x20 injectors and i know it could go alot furhter like 75, 80psi but i dont have the head for it not untill early summer, no problems with the head yet


thanks everybody for the imput i will let you know tomorrow what happens

Mine does the same. If your rpm lever is sitting on the pump casing at idle with no screw, you're fuel screw is in really far. I would back it out 1/4 turn at a time to stop it from running away. Thats just how these 114 pumps are with stock sticks.

daking

but i dont have stock sticks i have 6x20s in it, but i still thinking its just about to run away, becasue it ran away then i backed it back a quarter and now its on the verge of running away, and no its not sitting on the casting is 1/8th off of it, its hitting my fuel line on the other side,

its funny how diffent the two pump are, the fuel screw was in as far as it could go and the throdle was hitting the case and it was still idling to high
