Reviews for Crown Automotive BBD42S Carter BBD Type Carburetor for 81-90 Jeep Wrangler YJ & CJ with 4.2L & without Electronic Feedback (Export Models)

Bolt on performance without all the garbage wiring the factory insisted on using.

Very easy tool to order and checkout.

This carb was an excellent upgrade. PLEASE NOTE: I AM @ SEA LEVEL. Your tune or bench tune my differ. I set a basic bench tune in order to drive it 45 min to the dealer so they could dial it in with A/F sniffer and vacuum gauge. I set BOTH of the A/F mixture screws 2.5 turns counter clock wise (outward) from soft seat. I set the FAST idle screw 1.25 turns CCW (outward) from soft seat. A few pumps of the peddle to fill the float bowl and SHE FIRED RIGHT UP AND IDLED. YAAAAAAAAAAY...!!!!!!!!!!!!! LOL. Once she warmed up I adjust the idle (NOT THE FAST IDLE, mind you) to about 800 rpms. I drove her 45 min and there were NO ISSUES. NO stalls, NO sputters, nothing. In fact judging by my gas gauge she was still running rich. Hence having the dealer dial it in for me. Let's see how the longevity turns out.

My carburetor came but gasket was broke. Little disappointed

Don’t buy this carb. There is no air cleaner bail available for this item. Same with the electric carb also.
