Just got done using mine to work on a pac man board doing a cap change out. Wonderful tool. Glad yours is back up

Mine doesn't suck as strongly as it used to, (which ironically, sucks but not in the good way.)

I've cleaned the chamber but it doesn't pull up old solder like it did when it was new.

Anyone else experience this, or have advice to improve the ability to pull up old solder?

Do you ever clean out the nozzle and tips?

Clean tip and nozzle. New filter and metal filter piece on the clear tube.

I need to run to work, someone posted a nice guide somewhere and I can't find it. I've had to fully disassemble the pump to get flux cleaned up. It is much easier than the photos in the link below. This appears to be a catch-all guide on their site. Specifically my valve plate was pretty gummed up. Just go slow and look for orientation notches on everything you take apart if the above things don't help.
