The job wont be sorted untill you fix the hop issues.
I stripped 3 pistons before I got it right.Now I use a full metal tooth piston.
You need to make sure you use hop rubbers with very short lips.
I also shaved about .5mm off the nozzel at an angle to make it slip into the hop more easily. (original l l . modded / \ )
There are some on ebay for £4 that I use with no problems,pm me if you want any more info.
