Those are V6 carbs and some 140 v4s......Do you need some?
Good mornin hows it goin? I saw your post here. The carbs you are referring to are these 1 3/8 venturi are carb bore? I have some 50 twin carbs rhey are 1 1/4 venturi and 1 / 1/2 bore. If these are in fact 1 3/8 venturi I am interested in locating some. Thanks, Bobby
the carbs talked about here are twin barrel carbs, no way to fit them on a twin cylinder motor.
they are for the v4 motors and have just the two bodies, 1 up top and 1 down the bottom.
You can run them on a twin, just need to make your own intake out of aluminum, the reeds in a twin are the same as the v4 reeds
The issue is you'll won't get the performance your looking for unless you port it for all the fuel and once ported for all that fuel it will be only happy on the top end.
you can look to some mercury 125 carb for a bigger single bore
No that's not really true now is it. When people use the twin barrel carbs for one cylinder they do not use v4 or v6 carbs. They use totally different carbs like those on the old 3 cylinder racing motors. V4 carbs and three twin carbs for the 3 cylinder look similar at a glance and that's it.
Go look on the mod 50 secrets and you can read about the twi carbs. But even they are not as good as the larger 56 carbs.

Critchfield 15" 56ci OMC
RapidCraft Cyclone 15" 56ci OMC
there ya go, you cant put them on without a lot of modifications, and even then you have start the motor revving it brains out,,IF you manage to start it.
the v4 carbs are not ever going to work good on a 2 cylinder omc motor. ever tried getting the main nozzles out of a v4 carb ? and then fitting a nozzle of the wrong size and type.
you could fit the twin barrel 3 cylinder carbs and just jet them .
lots of differences and plenty of people have tried them and come unstuck, not worth the effort... by the time they work you would of changed everything.
like saying a 13 inch tyre fits a 15 inch rim, you only have the change the wheel .
