Thanks...Mart...I have a 7042240 on the SF and can get the 73 for a spare, but not if it's not identical.
Functionally there is no difference assuming each is rebuilt and modified correctly and jetted the same.
Thanks Rob...Ordered United Carb... $50 off Adavance Auto if ordered online. Ordered 7042240 and of course 7043240 came yesterday...I took the Air Horn off this Eve to see if they did it right and no hook (clip) on Float Needle......Who knows what else is not right. Goes back tomorrow....I'll just rebuild the 422.
