We had a little issue with our dual jet, the needle got stuck and it started leaking fuel and we lost the vapor vent tube, I went to a carb rebuilding shop to get the vent tube, and he recommend that I cap off the vent tube and and all the vacuum lines running to the canister charcoal filter. The reason he explained was he has seen failures of the canister system and has seen charcoal in the carb before. Has anyone heard of this? I was wondering about capping off the lines, is this a known practice and if so where would I route the remainder of the hoses to? I have a 82 Cutlass v6 with the California setup. This vehicle is not a daily driver but more of a cruising vehicle on certain occasions. If anyone has experience with this I would greatly appreciate some help as I would like to tackle this this weekend. Thank u guys, u have been such a big help so far
