Looks good, but I would recommend tapping for a fine thread bolt for a more precise adjustment.

I didn't even think about that!

If it ends up not being precise enough I'll just cut and tap some more steel lol

Actually, a lot of the guys on the 1st Gen. Ford/diesel site have been doing that for several years.

They get the electric high-idle solenoid off of the older GM cars and have flip-a-switch idle control.

I am un-certain which GM cars have them; but, there are certain ones in particular that they prefer, as the solenoid mechanism itself is lock-screw-adjustable to dial in the exact hi-idle desired within the stroke limit of the device.

That's got me to thinking ; I need to put one on the wife's truck for cold mornings, maybe wired through a temperature switch for automatic operation, plus a switch that disables it when the shifter leaves PARK.

I think this is the route I will go on my idle adjustment.

A few improvements I intend are to use a Grade-8 FINE-thread bolt, maybe 1/4-28 which would pretty much match the thread-pitch of the factory screw.

I will reverse the direction of the bolt, such that the bolt's head is what contacts the throttle.

One more improvement will be a second threaded hole below the one pictured, with a bolt installed in the lower hole, with it's bolt-head on the forward side, such that I can adjust the head of the bolt to press against the timing-cover, thus bracing against the throttle-lever.

I will epoxy a wear-plate on the timing-cover where the brace-bolt contacts it.

What do you think ??
