I do this for my 521. If it sits less than 10 minutes or so, I make sure to hold the throttle open for about 30 seconds when I get in. It will fire up, but does shoot out some smoke. It only happens in the heat.
When I drove it in VERY hot temps, say 110+ in Vegas, it really didn't want to idle and had significantly more trouble starting. Idling in traffic it did not like. If I moved to Vegas, I guess I'd need to address this.
My 14" air cleaner doesn't leave much room for a carb spacer. Maybe 1/4"? I guess I could look at doing that. Or lowering the floats.
