30pict3 issues
Posted: Tue Feb 07, 2017 2:40 pm
HI.
Installed the "new" Bookwus carb on my '69 Bus. It acts like an 009 with the flat spot, most likely the accelerator pump. The throttle arm does not seat against the cam all the way without a light push.
Bentley says hook up a hose, measure output average of 10 pumps. Is there a driveway way to check this?
Car runs great at high RPMs but hesitates off of idle. Also runs well when cold, then the flat spot shows up when the engine warms up.
Also the idle air screw is almost fully seated. Is this related? Jetting?
Either way I think the carb has to come off for screwing around. Tempted to reinstall the 30/31 pict that has performed well for many miles...
