Looking for a carburetor air horn that will fit my 636SA. Not omix.

mbullism was gracious enough to send me a air horn but unfortunately it did not fit my carburetor. I am still looking.

Your measurement 2.4455” is meaningless. The “air horn” fits between the rubber seal and the top (real air horn) of the carburetor. The clamp fits where your caliper is.

Bruce, that 2.445" IS the outside diameter of the "real" carb air horn, part number 116554 (Carter part 6-312S for those following along at home  ). It's entirely the crux of the issue, as the "Horn", air cleaner to carb (part number 641918) has an inside diameter of 2.324". Almost 1/8" "too small".I put "too small" in quotes, because when I measure the "real" carb air horn, part number 116554 (Carter part 6-312S for those following along at home) on my 636SA I get .  . and the "Horn", air cleaner to carb, part number 641918, fits  Edited by mbullism - 17 Sep. 2022 at 6:22am |

OK, I thought Dennis was measuring the outside of the rubber seal. Now I’m confused.

It is not meaningless, it is what the outside diameter of the the rubber on the carb  I thought the rubber seal was suppose to be between both pieces, clearly I was wrong. Went outside and removed the rubber seal and you already know what I possibly said to myself  I really hope I'm not the only one whom thought this. For the crossover tube does the air horn butt up to it, go over or in? |

The air horn goes inside the crossover tube, and then a rubber seal, again, goes over the joint to seal it.

 Now I'm confused (I thought you were measuring across the metal of the "real" air horn in the two relief cuts in the seal
... kind of like I was measuring the "real" air horn below the clamp and the crossover tube horn)Edited by mbullism - 18 Sep. 2022 at 7:00am |
