I'm New Here
I have a Marvel MA-4SPA carb on my 0320 powered 6. Recently, I have experienced a problem shutting down the engine when pulling the idle mixture to cut off. The engine continues to run at very low rpm and very rough. The only way I can kill it is to shut the fuel selector to off for a couple of minutes then pull the mixture to off...and it shuts down as expected. I replaced the float/needle and seat thinking this was the problem but it continues. I have played with the idle mixture setting too to no avail.
Does anyone with extensive carb experience know what my problem may be. Also, what should the idle mixture setting be.
