2 5/8" Opening for Rochester carburetor (Use 3" on MerCarb Applications)
- Stamped 571504AA, but should be the same as 571504A
Overall good shape
- MerCruiser P/N 86270A1
I'm pretty sure they glued these together and the glue appears to be good on this one. If you do have one that seems to come apart in pieces it's relatively normal, and when attached to your carburetor with the nut on top of the stud should hold everything tight together, but this also can make cleaning easier.
Flame Arrestor is pretty much universal with most Rochester 2 Jet carburetors used on 120hp 140hp Engines, just make sure that the opening is the correct size
Sometimes the little bracket that holds the flame arrestor tightening/mounting screw needs bending or modification to fit flame arrestors.
