Well I got the Pony-carbed equipped Weasel emission tested.
It passed mass state emissions with no real problems.
I have a pony carb ,Cat con, header and cam. I stuck a can of emissions pass cleaner a tank of gas ago, and then added
2 cans of dry-gas and set the timing to 12 deg BTC. (I have read that setting timing a few degrees back will help the
emissions levels.).Other than the problem of running the
truck with such low gearing on the dyno it passed with
flying colors. (Good for 2 more years..) The engine is new as of last year BTW..(Rebuilt.) Just wanted to pass it along as I know Jim was wondering..
