Re: Q Jet spacers, Q Jet upgrades
assuming you are talking about a 2" open spacer, there is little to no differnence amongst brands. The 4 hole pnenolic insulating spacers do vary I have heard ( no personal experience).
As for the carb, if your guy does not specifically know Q-jets he may think its stock when its not.. But there are lots of little things inside you cant see. A 'stock' carb would be an enternity slower than a Boburka. If you have another carb thats within .04 of a Boburka, its a good carb.
