Our records on this one are brief, so we can't speak to specific jet sizing beyond what's stamped on the part itself (this listing corresponds to the 420 size marked in older catalogs). If you're not sure whether this is the jet your carb needs, give us a call before you order and we'll help you match it up against what's currently in the bowl.
