[85 GSL SE]

Well I have a new main converter now. It improved the emmisions about %30 but is still double the gross polluter levels.

The smog guy thinks it is running rich. Can you recommend a good rotary mechanic in SoCal. I live near Temecula.

Do you think I should replace the first and second converters also? They are original, but not broken up like the main was.

I am acquanted with a guy who builds rotaries for dune buggys. Does anyone have experience taking their rotary car to a rotary buggy guy?

Thanks for all the help. I am new to the rotary world, but really want to see this SE back in shape. Any help is greatly appriciated.

Temecula huh... bring your car on down to Independent Honda Mazda Car Care in Escondido, look em up...talk to Larry..he knows his stuff but can be very busy. Down the street from him is Mechtech..they build rotary sandrails.

On my '84 -SE I originally failed emissions with the original cats in place, then I put in a generic 3-way cat, took it back and STILL failed..

HC's were way above the norm, which meant it was running rich as well

Instead of trying to lean it out, I added ~2L of methyl hydrate to 1/8th of a tank (along with replacing plugs,wires,dizzy cap/rotor, air filter)
and re-routed the Air pump straight to the cat - bypassing the ACV..

It passed by a LONG shot.

So, my first guess is that your ACV is bad

Sounds very similar to my problem, I will look at the ACV

At idle to about 3000 rpm, the cats NEED O2 pumped into them to convert the HCs...there isn't enough in the exhaust pulse to do the job coming straight out of the engine...three way cat is mandatory to pass emissions...

yeah its your ACV...
