Sorting out the Apollo's grinding gears.....Not really a mod but not sure where else to put it - just some advice for other Apollo users....
So i stripped down and gutted out the locks from my Apollo yesterday and it improved two things - it's now an easier prime as you reduce a whole load of friction, and secondly it's soooo much smoother. Gone is the grind and in it's place is a smooth priming draw.
I followed this tutorial https://youtu.be/0WNGniC71DY although i missed out the tape under the O ring, and took out the air restrictor which no one else seems to do (wonder why - will report back!).
