I think it's the carb, Too mush fuel Options

[RogerYellow914]

The car was running fine. Then last week, it started to pop and backfire on the freeway at 70 in 5th. It did fine in 4th at 70. Later in the day going up a grade at 70, it started to backfire real bad and lost power. I pulled over and it wouldn't idle. It was hard to start and then died. Investigation found fuel on the air cleaner cover on the passenger side carb.



Is this an indication that this float is bad? Is there a way to test the float vs. the valve?



Does this look like too much fuel in the bowl?

Thanks,

Roger

I finally had a chance to start working though this today. I started with a valve adjustment. I pulled the plugs to make it easier and found this:

The center electrode on 4 was burnt away. The body is discollored like from heat. There was carbon connecting the electrodes on 3. 1 and 2 looked perfect.

Adjusting the valves, I again found that even completely loose, the valves on 3 and 4 were barely in spec (.006 intake and .008 exhaust). I thought maybe the adjusters are worn, so I pulled off the rockers. They don't look bad:

I have some new adjusters I ordered from the Bird. The say they are for 2.0, but are much larger than what I have. What gives?

Also, when I put it back together I found that the nuts on the outside studs were not the correct thread. It didn't torque correctly until I replacedwith the correct size.

I checked the carb linkages. All fine.

I cleaned the carbs. Rebuilt and blew out all the passages on the 3/4 side carb.

I put everything back together and it barely started. It runs like crap. Won't idle. Barely any power. I'm at my wits end. Any idea where I should go next?

Thanks,

Roger
