Nikki 2bbl help?
Looks like the old carb did have ported vacuum, above blades. vacuum hole is about as big as this period. . Thanks for the support. Im thinking the transfer slot is out of whack with my fiddling trying to get the butter smooth idle. Should have dont that after it passed...first year- carb out of the box- it passed with flying colors. How much of the transfer slot should be exposed at idle, square like a Holley?
On the carbed 80's carbed four banger idle: It's a four cylinder,it's gonna have a slight twitch to it,when right.. It's carbureted,with a cat,it's gonna need to be slightly rough,to pass Cali tailpipe..(Used to be easy on four cylinders ,in the day..you are allowed 3 degrees retarded initial timing,for excessive h.c/C.o. readings....
You want the leaner side,on the vacuum gauge curve,...a couple of inches below peak,hurts nothing..If it idles slightly rough,touch that idle speed ,to 1000-1100...(should be close,to the allowable CARB/BAR Cali limits..) Raised idle speed,near stock ,slightly retarded timing,are your best friends...A freeway drive down the freeway,just before your smog appointment ,does wonders to light it off. Lazy ,non reacting cat? Hit it ,with a propane Benzomatic torch,wake that puppy ,up.(Still love the pictures,of the three angle valve job tool,with brake bits...)
