Zenith Jetting
 

Any point to jetting the Zeniths on a stock 2.2l?

Why? Has anything changed in the configuration? Are there any issues?

they came on the 2.2s, so the jets should be fine, other than the idle jet, which should be enlarged to 0.55, if it's smaller. this hlps to get rid of popping and greatly improves cold running and warmed up acceleration below 2500RPM. mixture screw readjustment required.

THANKS GUYS

Sorry to hijack the post but will the Zeniths work OK on a 69 911T 2.0 that was originally fitted with Webers? WIll I need to rejet them?
Thanks,
Kevin

Yorkie, I ran them on a 2.0E for awhile, everything was fine just a tad rich. I leaned out the idle ever so slightly to compensate a little. I'm now running those same carbs (with 38mm venturis installed) on my 3.0SC motor.
