you fabbed up a set of he's thru a cat and then thru a muffler.

This is for your V8 powered 914, right?

delaware is 1968 and older : (

looks like i need a 356 to drop a v8 into : ))

i passed two years ago by just taking my air cleaner off for the test, as i had a very restrictive one on at that time. but i would also like to pollute less.

subaru power would be better for the environment.

Jim,
That train left the station 30 years ago, LOL

Seriously, Your close and if you can run the test without a air cleaner, well that sounds like they don't look to close at anything but what the readings. Retard the timing, tighten up the idle CO and run the idle speed as high as you can. Idle speed / circuit is the hardest area to control emissions running a carb(I'm sure someone will disagree). so raising the idle will help a bunch. I'm sure there's a limit so I would find out what it is.
