69 carb issues

I cleaned the idle jets last week and she started and idled fine. I haven't driven or started her since. Now when I started her up it is spitting smoke out of one of the carb barrels. What could cause this. I haven't balanced or adjusted the carbs yet.

Probably more dirt in your idle jets coming from dirty float bowls and passages.

Its probably time to pull them off for a good cleaning. Also check your gas tank and filters as the source of contamination.

Webers love CLEAN fuel.

It tank and filters are new but I haven't touched the float bowls. Does that require you to remove or rebuild the carbs or can you do it with them on the car? Thanks

It can be done in the car but so much easier outside on a bench. hard to get the bottoms of the float bowls in the car.

I usually soak them overnight to loosen crud in the passageways and then blow them out with a compressor. This usually does the trick.

Its only 16 nuts. 12 manifold and 4 linkage.

Thanks. This will be one of this weekends projects. Shifter bushings came in today so I may finally have her on the road for the first time by early next week. I feel like a kid waiting for Christmas. Lol

It may be dirty carbs, but I would adjust and balance the carbs 1st, to ensure that the basic tuning procedures have been followed......and then if the condition persists....take them off and clean them up...so much easier on the bench........

regards,

Thanks. I have ordered new velocity stacks as mine are a little melted around the top and I can't get a good enough seal on my carb balance gage. As soon as they are in, hopefully this week, will be able to balance and adjust.
