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 ?
I started with nothing and still have most of it left.
