short answer: yes
long answer: no.
most snowblower engines dont have air filters... because there isnt a lot of shit in the air in the winter.
however, in the summer there is a lot more dust/etc in the air which can dramatically reduce the life of your engine/carburetor when it gets sucked in.
If you plan on running engines for a extended amount of time in the summer... i would say find a way to install an air filter, then re-adjust the mixture screws after you get a filter put on.
whoa. your right.
LOL idk i guess i didnt really read it that thouroughly...
as long as it has an air filter and wont overheat i think you should be good.
idk if snowmobiles come standard with air filters.
You can, depending on the engine.
Free air... no
Fan cooled... yes, provided the cooling fins are not broken, not plugged...etc.
Liquid... sure. Just needs a radiator of some sort, a coolant overflow tank and a way to move air thru it.
sure can. a friend of mine made a homepad 3 wheel trike, it sat about 2 inch off the ground and had a stright pipe in the back for an axle. he put a 299 snowmobile motor on it with 14inch tires.... did 70 easy... and what a burn out! but we never did get around to making brakes for it....
