Carb Vent Lines

you should not have to plug the drain plug, it has a one way valve in it. i never pluged the one on my rubicon and it was always fine.

i was having spitting and sputtering problems when i got into deeper water so i plugged mine and i haven't had any problems since.

Check the drain tube out......I have 3 hondas, my 2000 Rancher has an inline check valve - no plugging needed... my 2005 Foreman and 2006 Rincon DO NOT have the inline check valve. They both would get water in the bowl. I put the plug in, and these bikes swim now. If in doubt....plug it!!!

Im kinda confused cause some people are sayin plug the drain plug after you re rout your vent lines from the carb and some say dont. What are the reasons for pulgin and not plugin need some pros and cons can anyone help me out? if your not sure and youve done it then tell me the reason you did it.

[/quote] I have a buddy that asked some experts at honda and they say that the new hondas dont have just a one way valve and water will get into it if you get in some deep water. So plug it and that should cure your problem.

From what I understand, some Honda's have the check valve in the line and some don't. Even those that do have the check valve can't be trusted. Apparently it's quite common for that check valve to leak by and allow water into the carb. Though some get lucky and it doesn't leak, many others do leak and they learn the hard way. I would plug it if I were you, it's cheap insurance. Just unplug it at the end of the ride.

Just plug it either way its not going to hurt anything as long as the float doesnt stick you dont need it to drain
