Here's a quick question you might be able to help out on. The cylinder is a little bit sticky - it needs a bit of lubrication. Can you suggest anything? I guess when beer gets in it, it should be fine but anyway.. any ideas would be grand!
The Angram I have uses a different type of seal and didn't need any lubricant. As you say it should free up once you pump beers through.
ManseMasher uses this (taken from the other homark rebuild thread) which may work.
