81 KZ305 project

Yea that should work only differenc between the 2 is the casting mount location so a bunch of washers will take up the space if its the different version

those koso carbs are evil crap i have tested 10 of them and no 2 are the same for flow and finish

the fuel inlet nipples fall out

the throttle return springs are way to weak so if it starts the slides wont drop

and 4 of them were damaged

good luck to you keep your hand near the kill switch
