Classic 68 Valve - doesn't take level 10

[djinnform]

Are some of the classic valves incompatible with the level 10? The bolt wont slide all the way down the power tube? I tried to put it on a "Field" stamped 68.

I believe the "rental" version of the classic valves had a restrictor in the power tube that limited the maximum velocity.

I have heard that they can be drilled out though. I've never personally had one so I can't say for certain. Hopefully someone who has can chime in on this.

That is a rental valve as indicated. Yes, the powertube can be drilled out. I can't remember the size of the drill bit off the top of my head.

Yes. You need to drill the small hole out to the next larger one.
