PBR 1242 Carb:

OBR exclusive Wt-1242 carb is a modified (not bearing modified) carb directly from Walbro built to OBR specs! They used nothing but the best parts and this carb comes standard with a spiral diaphragm, all teflon gaskets and an ethanol resistant primmer bulb. They also modified the metering to deliver the fuel needed for high performance engines. No need to pull your new carb apart and change/cut metering springs. Between the primmer bulb, teflon gaskets and spiral diaphragm running fuel with ethanol is no longer a problem.They tested on all of our engines both piston ports and reed with great results. This carb will also run well on stock engines but it will shine on ported engines that need the extra fuel that this carb can supply.
