3406 B failed emissions in NY

Well, a week ago last Thursday night I shut down (empty) at the East Schuyler rest area on I-90 in NY. Friday AM I drove `5 minutes further east and got off the I-90 toll road and lugged her into the cash box to pay my toll. I lugged it in so it wouldn't be too loud for the toll collector. Well maybe there was a little black smoke or maybe the EPA and NYDOT had a hard on for an old Pete because the revenuer man waved me into the lot for an emissions test. "I saw a little smoke", he said.

The EPA guy comes over and says what year is the truck I say '86. He says we're going to so a snap accelleration test to measure smoke. I showed him my E-test cert from Ontario showing that I it passed with only 1.4% opacity of an allowable 55%. He didn't care.

He asked what RPM it's goverened at I say I don't know. He told me to rev it until we find out. 2700 rpm and still climbing be admits it appears to be ungoverend but he will do the test anyway. He puts a little dream catcher looking thing with a pantyhose on it over my stack and tells me to rev it up. No smoke but he didn't like how I was applying fuel...said I was rolling on and off the fuel too slow. Told me I had to "floor it and hold it for 4 seconds". I said no idiot drives like that. He didn't care.

So I floor it (almost) and of course he measures 72% opacity and I fail. He issues me a ticket for $700 and I am on my way.

Last Friday (3 days ago) I took the truck to my local certified emission test garage for a test and they measured 1.2% of an allowable 55% opacity.

I feel if it was goverened with a rev limiter I would have passed, and since I rarely get over 1800 anyway, I thought I might like to govern the truck at ~2000. How do I do it?

P.S. After a little surfing the NY website, it seems they use the SAE J1667 test procedure which clearly states that if the engine is not governed, they are to abort the test. Seems like I will be pleading not guilt to this ticket.

 

This is a mechanical engine. Not a computer in sight.

 

The NTC's were mechanical if I remember correctly? How does a delay switch work on a mechanical engine? I thought the answer was going to involve springs, screws, weights, baling wire and maybe even a block of wood under the pedal.
