That was very popular at the track in the 70's. We used them on snowmobiles. Has the advantage of being very quick, especially on the open velocity stacks we were running then. It wouldn't be as effective when you are attaching air tubes to an air box after you're done, but probably still better than the ears of most inexperienced owners.
Nah, they are going into the trash. I was considering dropping them in boiling water, then attempting to use a bearing puller on them. I guess I could also put the grinder on them and just chew through all that rubber :/
So, I was replacing all the gaskets in the carbs today, and one of the main jets was pretty clogged. I went ahead and removed it, but the spring under it bound and got kinda bent out of shape.
I don't even see this part in the diagrams, does anybody have a lead on these?
