governor mod

[myvolkswagen]

so i just finished shiming the governor and i have it all put back together but i was wondering if there was a possibility that it could be at wide open throttle instead of idle. it pops back into its regular location like usual when i let off the throttle but im worried because i dont want my freshly rebuilt engine blown up. could i have screwed anything up that would result in that? I was weary about opening up a pump for that reason

Why dont you start it and see if it starts to take off? If it starts to take off, turn it off.

Did you mark the top of the pump on the shaft-to-arm pieces? If not it is entirely possible you have it either WOT, or the pedal will do nothing when you depress it.

Have you read the HOW-TO in my signature?

There is a chance that the engine could roar to life.. and turning the key off won't do anything.. so when starting it YOU NEED TO BE PREPARED TO SNUFF IT OUT BY DUMPING THE CLUTCH AND HOLDING THE BRAKES.

I could give some more advice, but before I do.. i need to know how you went about doing this procedure, else what I tell you could be wrong.

Well I disassembled the pump like mentioned and I kinda went off the orientation if the line on top of the throttle shaft as to which way to put it back on but I didn't mark it so I guess it could be lined the opposite way. However, I believe it's the idle screw I had out and the shaft stopped after going so far. I feel kind of stupid for not marking it

[vanagonturbo]

Mr. Fury, roaring to life and not being able to turn it off would be a different problem. I have messed with these pumps on multiple occasions and never come to a point that engine was screaming away and would not turn off. Of course the engines that I worked on whilst doing these tweaks were not on their last legs and pumping oil into the intake to keep running. jsut thought I would put that out there..

[myvolkswagen]

When I put it back together the shaft was on full release because the throttle will stop at a certain point when released which would mean that fuel would be cut all the way back wouldn't it? Seems kind of fool proof I think because those levers inside the pump that the throttle is attached to are spring loaded. When I put the pump back together they had to be moved forwards so that the top of the pump would go back on. I could be comPletely wrong too

i guess you can put the shaft in 180* off.. but if you follow the pics of the mod.. i do not think you have anythign to worry on..

when i did mine.. i had to turn the idle screw all the way down.. it would rev to life and carry its self away if not.. so be ready to do that...

you can install the throttle shaft 180* out, but it wont hook up to anything.. the governor wont hook into the fulcrum plate without being lined up..

Better to be safe than to sit there and watch it go boom, eh? Was just giving pointers on what to do if the key doesn't work. Some dirt that may have gotten in the pump could very well hold the rubber diaphragm open that controls fuel flow to the injectors.

Not true, you can rotate the shaft enough so that the spot where idle is is actually negative to idle. Pushing the pedal or moving the lever on the outside of the pump at this point will only take up slack in the gov/throttle plate, not start to push the shaft inside the pump. Going the opposite would be like taking idle and putting it up higher, so the lowest spot for the pedal to sit is actually maybe 1600 rpms.

If the pump was stock prior to this, id say leave the fuel screws alone for now and fire it up and see what happens.. be ready to snuff it out if you need too, and you'll be just fine. If the pump was not stock, and the "max fuel screw" has been messed with, back it out two full turns to start with.. worst this will do is not let the car start, but it wont cause a run away.

well, thats hardly 180* out jeremy.. that would be a FEW DEGREES, like maybe 1 or 2 splines..

[8v-of-fury]

2 splines in itself is (assuming around 20 splines) 18 degrees.

It is possible to get the throttle shaft to throttle arm pieces that 180* or atleast close and something that needs worried about.

I'm just voicing opinions on what I did as precautions to make sure I didn't blow up that I just modified to turn lethal rpm's.

Take it as you will.

no dude, you cant get the throttle shaft in 180* out, and hook it up too.. it would be hitting the side of the pump top, and not be lined up anywheres close to the fulcrum plate.. the shaft would be going thru the groove in the top of the plate at a 45* angle, if you could even get it hooked up..

take the top off a pump, look at the accelerator shaft, its off to the front (side) of the pump more one way than the other..

you cant line it up and make it run 180 out.. idk what brought it up, but only reason i say something, is because on the first pump i ever worked on, i TRIED to install the shaft 180 out, and it wouldnt even come close to hooking up to the fulcrum plate right..

idk, you might be able to get it hooked up if you forced and bent things..

but, ANYWAYS.. usually after the gov mod, you either have a constant idle, or your engine does NOT idle.. the key always shuts it off, unless you have other latent blow by problems..

[myvolkswagen]

Well if it can't run 180 out then I'm golden because everything functions and lines up identical as before I did the mod

[CRSMP5]

fyi... default on splines is middle line on the throttle linkage.. the shaft has a line too to line it up with..

being one line off back/forward wiil be idle issue.. thats abt it..

[theman53]

it is something that if you are off a spline you can take it off and move it over. Not a big deal either way.
