Use the search function.

members have been dealing with these issues on here since the dawn of Spudfiles.

here are a few example threads I found for you:

basically too much blowby on the piston or rather too much compared to the pilotvalve's flow causes these issues.
Snug fitting piston, still able to slide... and a good ( big/fast) pilotvalve fixes it.
