today i installed a new shutoff valve. i did it without blowing it up. well now i have another problem it doesnt start till i have turned it over several times. i have found the problem to be that the shut off switch is holding its vacuum after i shut it off. (if i dissconect the vacuum line it will start right up. so my guess is that the valve at the ignition switch is not letting the vacuum go when i shut it off. does this sound like that valve is the problem? but atleast it starts and shuts off. right? i would like to find out if that is the problem because i will be ordering another batch of parts soon and would like to order that too. any ifo would be appreciated.

As I understand it, you can expect the shut off valve lever to stay down for a while after shut off. It should pop up when you turn the key to run or start.

thats the problem. its not popping up when i turn the key but as soon as i disconnect the vacuum line it will start. that make me think its the valve on the ignition switch.

The valve on the ignition switch has a bleed function which, in the ON position, allows air to bleed into the shutoff valve.

If you reverse the vacuum connections to the valve, you will have vacuum leak problems, like my wife's car had when they replaced the ignition lock assy.
The car wouldn't shift until redline.
They reversed the vacuum hoses and it ran perfectly.

I'm just about to do this job, any hints would be appreciated! Did you remove the air assembly to make sure you could stop the engine? Or did you try the vaccuum check to see if the stop lever moved?

I know my ignition is fouled with oil fromt he leaking valve, does yours have this same issue? That could cause an electrical component to misbehave. Brake cleaner is the way to go according to the archives.

yes i did remove the air filter assembly. its possible i reversed them. last night i had to unhook it because it was making the car run rough and it wouldnt go. unhook it and off i go

the shifting is still a problem. im thinking its because i turned up the alda. i used the mitty vac to help me install it. i put the bracket on the vave then hooked the mittyvac up to it and when i felt it catch i squeezed the pump. it helped hold the valve in before i bolted it up. as far as seeing thr rack move it didnt when i tried after installing. but i know its in there correct because it shuts off the car.
