Smoke...from the carbbies.

~In a deep purple kind of way~

After about 60 seconds or so idle, I wanted to warm her up so I could do the timing, I noticed a little smoke.
I originally thought this was just oil burning from a minor spill when filling it, now I noticed it coming from the air filter (area).
Why would smoke (brown-ish) be coming from the intake side?
Bear in mind I have not done dynamic timing at this point, nor tuned the carbs properly since reassembly.
It has an oily nice smell to it, not as pungent as exhaust or sweet as coolant.
Again, no Doc, I'm not tasting it.
TIA chaps.

Geez, Barry. How ya gonna ever know which fluid is which if'n ya don't taste 'em all?!?! /ubbthreads/images/graemlins/devilgrin.gif

...I don't think smoke from the carbs/filter area is a 'good thing', BTW. Have you got a GOOD ground strap going from the chassis to the tranny? Reason I ask is: if NOT, it will ground thru the throttle cable and FUSE things. Think: lightbulb filament here!

...or how to make a Spridget bark... WOOF!

What do you have in the dash-pots?

20/50.
Now you mention it Mike, I may have a bit too much. Rich mixture and pancake syrup in the dashpots would make it do that right? I knew the mixture was on the rich side, which is why I put the heavier oil in them. That makes sense.

Why?? Med weight oil is what you want for street use, like 20 or 30 WT is fine.

Heavyer oil will surely work Barry. Heavy oil for street, light for track. Light oil will cause the engine to stumble a bit at low RPM but be more responsive at high.

20/50's fine. You gettin' a backfire thru the carbs, mebbe? Or the dashpots were a bit over full and squitter'd some out onto the manifold?

Yeah, sure it's a little bit of both....
Alright then, which should I do first, dynamic timing or tune carbs? Timing right?
