yes it will allow some adjustment. not sure but it may not give you as much at full throttle as before. id just back the high speed idle screw all the way out if you haven't already.

 

Bring the throttle arm back to the point you had it after the installation of the 366 then go one more notch counter-clockwise. As dieselcrazyw350 said backoff the high speed stop screw. Your 366 spring will start to defuel somwhere between 3000k and about 3300k. With the high speed stop backed off the engine might run at higher RPM but the 366 governor spring will will start to defuel as I said above. If I remember correctly idle is set with the auto tranny in gear and A/C on. It should be set at about 750 RPMs.

This may be a stupid question, but when you index the throttle, when you push down on the throttle shaft, are you rotating the shaft counter-clockwise and then pulling it up into the notches or are you rotating the throttle arm clockwise (with the throttle shaft pushed down). I've always rotated the throttle shaft. Push down, turn and then pull up. Am I doing it wrong or does it make a difference which way you do it? Also, I can't back off my high idle screw anymore because it affects the way my slushbox shifts. It puts too much pressure on the transmission and it hangs between 2nd and 3rd until I let off the gas.

 

If you marked the throttle lever and the center shaft - I hope you did - then you need to line up those marks and go 1 notch counter clockwise. You will need to test everything when you are done. That will tell you if you've set everything right. I know I turned the inner shaft but to be honest I do not remember which way. Just be prepared to shut the IP pump down manually if it wants to run away.

OK. I guess the gov spring is going to pull it around anyway, no matter which way you do it. So, going one more notch counter-clockwise will lower my idle as well as my top end? I wish I understood better why I'm doing what I'm doing. I know I'm pulling the gov spring tighter as I go counter-clockwise, but what is that doing? I guess I need VE Pump 101"

 

If you turn the shaft counter-clockwise you increase tension on the governor spring. This will raise the idle speed.

 

That's what I was thinking. So if I go one more notch counter-clockwise it will make it worse, since my idle screw is turned all the way out now. And if I go the other way with the shaft, as soon as I touch the throttle it dies. Any suggestions? And how does turning the shaft affect my top end?

 

we're just telling you how to adjust the idle after doing the gov spring and power screw mods.After turning up the fuel your idle will be higher,correct?You back off the idle stop screww all the way and it still isnt enough then you have to re-index the shaft clockwise then bring back your idle screw where it was so the spring tension is there.Do this with the engine running.Youll get a feel for it then.Take the arm off and have someone start the engine.Then work your shaft from there.
