OK, I was bored the other day so I decided to try a something new with my RX-3 and RX-7 (both equipped with big 13-B streetports and 48 IDA). But without a main jet...Yes, straight out F11 emulsion tubes and 170 air jets only. Something I've done before on bridgeported motors only. To my suprise, both cars idled fine and ran good without a main jet....the only problem was coming to a complete stop...the engine bogs a little bit which required reving the engine the clear the throat....Til now, im still driving around without main jet with no problem...kinda rich....well I dont care
