RE: Fox 4.2 runs erratic
I just had somebody look at the carb. They are all saying a combination of things, but all are leading to air leaks and the carb like usual. I cleaned out the fuel port of the diaphram and cleaned out the filter in the carb. I also found out something else; the plastic extention between the engine and the carb, if it is tightened too much it will actually buckle and let some air in. So I put a really fine layer of sealent around it to help reduce that problem. I was also told that the carb's metering valve may need to be opened a very very small amount to let more fuel in. Hence, why the engine must have a rich low end because its not getting enough fuel. Dan, you were saying something like that. How do I know how much to open it if I need to do this?
