this thing really worked today ! it looks like shit (not painted very well) but the dam thing worked real good ! the carbs were way out, now it runns like a raped ape !
its just 3/4 " box tube welded on both ends 1/8" pipe thread taped holes, 4 needle valves 4 3/16" by 1/8 npt hose barbs, had all the stuff at work(glass vial manufacturing) the gauge was not the correct size so i put a 1/4 " by 1/8 npt hose barb and hooked up a regular car vac gauge the valves can be adjusted so their is no flutter and the one gauge dose not have to be calibrated( because their is a difference between mutiple gauges) set everythig to 200 mm hg runs real good what a differance !
by using one gauge you dont get variences between 4 separate gauges you dont suck anything up and its dead balls, it takes a bit longer because you have to work the valves on and off but all carbs come out great !Im confused, one gauge to sync four carbs?
