Mercury Sidebowl Carburetor WMK 41-1B Series with Larger Jets in the 80s 115 HP

[sfara002]

Just writing to see if anyone had a good answer as to why these were the only sidebowl carburetors offered during the inline 6 era with the larger .076 jets when most others were .074. Was it because by this time Mercury knew these motors needed to run richer? And with changes in fuel specification in the mid/late 80s did they realize they needed a bigger Jet to keep the motors from burning up pistons at partial throttle?

Thanks in advance.

The 41Bs where on the 115hp and .076 was stock jet...the 41A was used on the 90hp and used .074s.....never seen A's on a 115hp.

Thanks Fazbullet, I will stick with the .076 jets then for the 115hp!
