carb bang

Hello ... I own a 93 110 pick up with a 3.5 twin carb v8 .. a few weeks ago i noticed the truck was vibrating and shaking more than normal and when i reach speeds up to 100-110 kph or when the engine is under pressure as in dune bashing i would hear a very loud bang and the engine dies then restarts in a couple of seconds .. so I removed the hood and drove the car hard and found that it was coming from the right carb ... I've never delt with twin SU s before so any Ideas ....
Thanks

also check that the pistons holding the needle are free to move with equal resistance, while you are at it check the oil in the dash pots on the top of the carbs.

would be a good idea to strip the piston housing off the carbs and clean all parts with carb cleaner to get rid of any gum, refill dash pots with engine oil.

also clean pipes from rocker breathers to carbs and clean/replace flame traps.
another a major cause of carb back fires is poor ignition timing.

have fun
