Aftermarket carb for 273 commando

Awesome, thank you, I'll look into getting a lighter spring. You're spot on about the wires chaffing, those and plugs are next after the tank acid wash, (the ol lady is already pissed I spent 325 on the carb, and the majority of the day we had off together replacing the timing cover gasket), but as per your advice, I'll reroute them until that time comes.
