67/68/69 cuda dilemma

Al, you may have to do it like I had to do my riding mower. I put a fuel shutoff valve between the tank and carb. Every time I get done mowing, I shut the valve off with the mower running, and let it run itself out of gas. The crap gas we have now sits in the carb and gums it up.....and I even buy non ethanol premium gas for all the small engine stuff! :BangHead: Cutting the gas off and letting it run out helped my mower run better though.
