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 |

The larger lugs are correct for a 73+ motor. Looks like someone replaced your rocker arms with the earlier ones, and used elephant's foot adjusters. I'm not sure if those are genuine 911 adjusters; hopefully they are. Those are the best quality but unfortunately they are expensive.
Has any machining been done to the valve side of the rocker arm? The face of the hole that faces the valve stem needs to be machined a bit to make for clearance when using the 911 swivel-foot adjusters. --DD |
