Two problems

[Brad kirk]

A)The idle is too low on my 93. That nut on the idle adjuster looks pretty inaccessible. What's a guy to do?

I think there is a vacuum leak when I keep my foot on the brakes for a bit. THe two warning lights come and the pedal will be hard if try to push down on it right after releasing it. I've looked over the vacuum lines but could not find anything damaged. Anybody had this problem?

Struggle till you get it.

If the pump has been clocked toward the head (for timing advance) you have even less room.

Back when i installed my governor spring, I clocked the linkage one notch back so i could place the idle nut on the front side of the pump casting to adjust easier.
