New carb

Tabbed · 05-28-2020, 09:59 PM

Installed a new carb today but on the old air filter box it had a crank case vent hose going into it I think nowhere on new carb or new filter does it have anything to put that hose do I just leave it open to.keep pressure down or do I pit a cork of some kind in it? Thanks in advance

Keep it open to the air. You can pick up a small crank case vent filter at Autozone. https://www.autozone.com/external-en...ter/153665_0_0

The standard way to do it was an open hose that vented an inch or two below the bottom of the engine. Thats what I use on all my bikes. Old cars used the same setup. Don't plug it. A filter is ok too but don't let it get clogged.
