No.35 is a grommet at the bottom of the crankcase that I believe has a hose attached that drains the carb overflow, and I think the vent hose is basically in the same area, and gets clean air being inside the carb enclosure. I THINK,lol.
Thank you so much. I guess that makes sense. I couldn’t get anywhere, and the dealers won’t touch anything older than 20 years. Ugh.
