So I think I'm done trying to get the stock carb on my 73' working correctly and am going to just get a weber kit. Here is the question, which kit?

 

K730 or K731?

 

Or is there even a difference?

 

Different sites have them listed both ways.

You need the smaller one piece adapter plate... I would assume this is the K730 kit.

 

Do you really need the kit? Often cheaper to buy the adapter plate and the carb separately. You do not use/need the throttle cable hanger parts included in the kit. You should use your current parts and swap the Hitachi throttle lever onto the weber. 

Thanks Leeroy, after doing some scouring, I did end up just getting the carb, air cleaner and adapter separate and saved about $60!
