Vacuum at Idle

Post by rtelford »

Hello All,

My old girl idles a little rough, I have adjusted the idle to 520RPM and have been playing with the idle fuel mixture. The shop manual says that vacuum at idle should be between 17 and 21 in. hg. however I cannot get it up 15 in. or so. Any tips?

Cheers,
Rod.

How is your timing ?
When you're faced with an unpleasant task that you really don't want to do, sometimes you just have to dig deep down inside and somehow find the patience to wait for someone else to do it for you.
