Hi folks
Just to let you know that while the gas valve works perfectly on the Quarry Hunslet, there seems to be some variation in the Edrig gas valve body meaning that the spindle might be too short for some. I had to modify mine on the lathe to get the needle to seat and I have heard of another with a problem. I have also heard of one that was fine. Jason Kovac is on the case.
The regulators are not affected and seem to work well.
Cheers
Chris
