I have installed the 366 spring a while back and turned my fuel screw in as far as it will go (no runaway). I have two questions. I still have 3 or 4 threads sticking out on my fuel screw but it won't go in any further. Is this normal? And secondly, my low idle screw is turned in as far as it will go (my throttle doesn't even hit it). Is this normal? Is this because my fuel screw is turned in? It is idling right but if I needed to lower the idle any, I wouldn't be able to. My throttle linkage is adjusted out just about as far as it will go. Anyone else have these issues and is this normal? Thanks.

 

the few threads sticking out is normal. dont try and force it to screw in any farther. you may have the throttle linkage indexed wrong.

 

All sounds normal, if you need to lower it a little nore you can always grind the linkage down a little.

 

You will need to re-index the pump. I had the same problem with my idle when my 366 spring was installed. I believe the procedure is in the "stickies".

My pump won't run away either, it will just "hang" at high RPM if I turn it up too far.

If you rev yours up to 2500 RPM, will it drop right back down?

 

Yes, it doesn't hang at all , even at WOT. There is a space between the throttle and the idle screw where it doesn't even touch. I think the throttle is resting on the IP. The throttle linkage is just about maxed out. I only have a couple of threads on each end. It's borderline idling too high, which I can live with. But if I ever need to adjust it down, I can't. Any suggestions?

 

re-index the throttle linkage

 

I removed the throttle linkage and adjusted it so the heim joint lines up with the ball on the throttle when it is in the idle position. The throttle linkage is almost to the end of it's adjustment. Even with the throttle linkage removed, the throttle still doesn't even touch the idle screw. I think it's hitting on the IP housing (it's hard to tell exactly). I don't know anything else to do with the throttle linkage. What do you mean by re-indexing? I didn't see anything in the Sticky.

 

this is what im talking about.

 

Did that. I took the top of the pump off Friday to replace a leaking throttle shaft o-ring. I indexed it back to exactly where it was before. I tried a couple of notches clockwise of the original position but it wouldn't run right. I didn't try to pull the throttle shaft around any further (counter-clockwise). Are you saying that's what I need to do?

 

Try installing the shaft ONE notch clockwise (in the picture above, this would be setting the slot with the last hash marks on the plate, if it is currently at the second to last), and setting the idle screw out so it is holding the lever up a little. Even with a stock set up, you can get the engine to idle one notch off -- but then you can't adjust for full rpm's on the other end.

 

I tried that and it would idle fine but as soon as I mashed the gas pedal it would stall. I might be able to go the other direction but I don't know what kind of effect that would have.

 

the engine stalling with it one notch off doesn't make sense.

 

You need to clock it counter-clockwise.

The throttle shaft? Will that allow me some idle adjustability, which was my original issue? What else will that affect?
