I don't know if there's a new way to install the air boot that goes from the bottom of the air cleaner to the carb but it sure is hard to do.

The boot I have has gotten hard as a rock and was very difficult to slip on the carb, until I got out my hand held blow heater (looks like a hair dryer) and heated it to make it more plyable.

After it got warm, it slipped on so much easier..

I hope this tip helps others
