Choke actuator Line

Can anyone tell me if this inline filter (maybe) is supposed to be in here? Thanks in advance!

 

I believe it is a one way vacuum valve designed to hold pressure and the choke open. I tested mine and it appears to have had a leak, not sure if that is how it is designed but I was having problems with my choke. After many hours of frustration, I removed that valve and replaced with just a straight through vacuum line. My Sambar now starts without the excess choke causing all the smoke etc. and runs fantastic. I am leaving off for now and may order a replacement next time I need something from the Japan part supplier.

 

That is a vacuum control valve. They can be a one way valve, a delay cartridge, or a combination.

 

That is one dirty engine.

 

Too many off-road trips I suppose. What’s the best way to clean it? Was always worried about exposing the engine to that much water.

 

I use a citrus based cleaner. Soak it and hose off. just watch getting the distributor too wet.

 

Is there one I can buy at a regular auto parts store. I suspect mine is starting to get faulty.

 

They used to be fairly common. But they haven’t been used in stock applications since everything got fuel injection, and electronic engine management.

They show up on eBay, but that is kind of a crap shoot. And, folks want twenty dollars or more for them.

You can test yours with one of the hand vacuum pumps, which can be bought for around $30. Hardest part of testing them is finding information to tell how which direction the stop, and which direction they retard the air flow, and. How long it d should take to bleed down from what vacuum level.
