1st off..are the blower style carbs ?...your info is somewhat right to a certain degree...it will run with any carb you can get bolted on to it...the key is getting all you can out of it with the fine tunning..
blower carbs give off a different signal than normal aspirated carbs..

i am not a carb expert..but i would say if you haven't used the carb return it for a correct match or see below..

now i have a guy here locally that can go into those carbs and match them right up..his name is John Poyer...owner of Poyer racing...he is not half cocked carb man...he has awesome flow carb benches..etc...1st class set up..i let him go thru my 1050 and he gound me over a tenth in carb work alone...if your interested i can give you his number...he has many of his carbs on some super gas stuff out of Florida and all over..he moved here from Florida 12 yrs ago.....

Many people just overlook ( take for granted) their carbs. fine tunning the carb is all about squeezing out all the motor can give once you got the rest of it working as it should.

let me Know if i can help....Brian
