latest observations
latest observations
The latest observations: I took off the tube that I thought controlled the choke opening. With the flare and compression fittings it was attached with, it seemed that hot water flowed through it to control the choke butterfly. I then ran the engine until warm, no water came out of the opening. Plugged manifold opening? ('72 era 2 barrel Rochester carb.) While looking down the throat of the carb with the engine running about 1500 rpm I see gas running in with large drops on the port side barrel of the carb, while nothing appears to be metering in on the starboard side of the carb. Below this carb side by side are the adjustment screws(2). To see the effect I screwed in the port side adjuster until it seated with no affect on the r's. This was the one that I could see the drops of gas dribbling in. It looks like each screw governs its respective carb barrel. Is this correct? Is the carb in need of an R&R?
