Can anyone help identify this set of OMC 3Cyl carbs? the casting on the body of all three is 321406. There is a "70" marked in ink/paint on the top of all three bodies, and the front opening is 1.5" photos: http://mattmak.com/photos/omc_3cyl_carb ... /index.php The interwebs haven't helped much. Only found one reference. thanks, M |

Well, I kinda reverse searched for similar looking carbs via google images and it looks like they are early 70hp, so like 1974 or 1975? The next question is are they useful for anything? I do plan on restoring a very early 3cyl for nostalgic reasons and am wondering if these will work with the 1970ish 60hp block.. |

These sound like the standard carbs for the 49.1 cid 60, 65, & 70 hp. Do they have manual choke plates and are they 1 3/8" bore on the intake plate side? |
