Pin drills are on the way. Gonna yank the carb again tonight and break it down for another inspection and cleaning. Will measure all bleeds and report back with results and some pics of metering block.
I’m beginning to wonder if ordering a Proform main body isn’t the way to go here. Could be money well spent if I have to go down the rabbit hole of drilling or filling these factory holes.
Haven’t seen any follow up on what you ended up doing. What and from where did you source the pin drills. I’m not seeing much for drill sets in searches for sourcing the bits needed especially for the IFR’s.
