I've got a proform main body that both accel pump circuits seem to be clogged solid. Bowl and metering blocks are clear, as are the nozzles, but I can't get any carb cleaner through the body. I can spray either direction and nothing. I bought some cheap little carb brushes https://smile.amazon.com/gp/product/B076LJSY3P/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1but I can't get them wormed up in there, maybe too big? How do I break the log jam? Thanks

I’m assuming you have the check valves/needles removed.
If you’re only dealing with the main body, there isn’t much to it. Two holes at 90* to each other, connected at the intersection.
I’d just use a small drill bit and spin it in with my fingers from both sides, or a stiff piece of wire, like a paper clip.
If you use a drill bit, be sure it’s smaller than the ID of the seat for the check valve so you don’t damage it.

I got that set on ebay for $7.00 shipped. Getting those pin drill bits back in the correct spot is a real challenge.

Never heard of it clogging in the main body. No air? No carb cleaner? I'd be in there with a light and a probe making sure it was even drilled all the way.
If the results don't match the theory, change the theory.

I have seen squirters not drilled all the way through.

Bowl and metering blocks are clear, as are the nozzles, but I can't get any carb cleaner through the body. Seems pretty clear the squirters aren’t plugged. Never heard back about the check valves/needles though. I'm sure your problem is the check valves under the squirters. That was my first thought as well. I’ve had them stick in the bodies numerous times.

haven't got it on the car, but finally did get the needles out. They were pretty stuck. Maybe dumb luck, but I've never had one do that.

I just fixed a VW beetle carb for a hippie I know. Same deal, stuck check balls = no acc. pump.
The ethanol fuel does a good job of gumming things up. Its some valve sticking bs they are selling us.
