Engine case rear (transmission area). There are two vent nipples, a large one and a small one next to each other. What is the small one for? I have nothing on it...should I?

Freefam, the larger nipple is the crankcase vent. It should be connected to a hose that runs up to the nipple on the front of the air box, by the carburetors.
The small nipple is the vent for the middle drive. It should have a small hose on it that runs up between the battery and the air box, underneath the fuel tank to a bracket.-- Scott
