I've been searching and couldn't find a good writeup on how to remove/replace these jets. There were a few threads on this forum but nobody seemed to have that particular answer.
I tried heat and a screw with slide hammer on one, but it wouldn't budge.
Also if anyone has any information on converting these to screw in type I would appreciate that too. Would drilling the stock jet oversized and then threading the inlet of the tube to insert a removable restriction orifice be a possibility? I have the ability to make the orifices at a machine shop, so I was thinking that would be a cheaper alternative to converting to real OEM screw in jets.
