I have a gas filter you can have for $5 to cover shipping (I'm in Canada). It's a 3-port one but you can just cap the extra port. Just PM me your mailing address if you want it. Ps, when people talk about "sliding into DMs" I get annoyed and think about how we have called them PM's (privat...

Title says it all. I need that dreaded TVSV and the intake "gas filter" because i somehow managed to break both of them while installing the motor.

Hello,
Looking for a good TVSV. Thanks, Jess

... 3 ports. There are at least 3 kinds of vacuum advance units: 1 port vacuum unit: 1 line to carb. 2 port vacuum unit: 1 line to carb and 1 line to TVSV due to emissions (TVSV at manifold). There could also be a variant, which has a line to carb and to height compensation system. 3 port vacuum init: ...

... up the line to the "gas filter" (per page EC-38) it's the port that had 2 lines coming from it and the other end connected to the TVSV The upper port with the smaller opening runs to The metal vacuum piece which splits off and runs into the choke breaker (as far as I can tell, ...
