Well i would like to change my Air filter to goe strait back instead of bending up. The only thing stopping me from doing this it there it a suction tube from the crankcase going into the bent tubing. First picture shows this. Is the tube needed for the carb to run correctly? If so how could i make the air filter go strait back.
I believe the suction tube is to capture crankcase fumes and blowby. Probably due the goverment regs. I'd put a short hose on it and point it down, open to the atmosphere. If you get a lot of oil residue coming out, you can cobble a hook up to the air cleaner. Enginne will probably run better without burning all the oily fumes.
