Anti-backfire valve

[ben510jones]

Hello Ratsun land,

 

I recently bought a 1978 620, and I'm trying to get it all put together so it will pass emmisions. (All the emissions stuff was either missing or disabled when I bought it) So far I have been able to find everything I have needed EXCEPT for an anti-backfire valve. None of the parts stores even list it.

 

Does anyone know where I can find a new anti-backfire valve? Or is there another name for it? Or an alternative part that does the same thing? Or does someone have a working "spare" that they would sell me?

 

Thanks in advance for the help,

there are 2 dealers in u.s. that still show this part in stock buena park nissan ca.ph#714-739-0800 and ponderosa motors nissan wa.ph# 509-765-1774 part # 14835-b8003. call these dealers and see if they'll ship it to you.MSRP is $75.12 :D

just time it and run it thru,see what happens

Thanks for the lead about the Nissan dealers...

 

I ran it through once and failed the visual inspection and the loaded tests, and barely passed the idle test.

Now I'm not even sure they even consider the anti-backfire valve part of the emissions equipment, so maybe I can try taking it in without an anti-backfire valve, and see what they say.

Do you think they'd fail me if it was backfiring every time they shifted? ;)

fail visually?

 

Most time once the aircleaner is ON you cant really tell whats what.

 

I had passed with dual Mikuni carbs. adjust the mixture and Timming. and that should help.

 

take it to a smog shop if all else fails and dial it in before going to testing.
