the venturis and the throttle plates are the difference in carb sizes.if you could finda junk carb and swap the parts?my bro has a 650 and the venturies wereallot smaller than my 750.
There's another way to look at it: You can take the fuel bowls, metering plates, vacuum diaphragm, feed line, and choke off your 3310 and put them on an 850.

In other words, the things that don't have anything to do with flow are what you can take from a 750 and put on parts that flow 850. The body (with booster venturi) and throttle plate determine flow, buy those 850 parts and put the rest on from the 750.
If you've got an 850 that's got bad or missing float bowls, throttle plate, metering plate, or choke, you can take those from the 750.
