Ego 11 velocity issues.

Ego 11 issues. Working on friends marker unfortunately it had sat in a closet for over 10 years solenoid was stuck but luckily got it to move.

Once I was able cleaned and changed seals I would get 1st shot drop off and velocity could only get as high as 250fps and if you didn't shoot for 5 seconds next shot was 150fps. Tinkered with the dwell upp,d to 18 good difference could get to 300 fps turned down the reg.

Solenoid seems to probably be the issue i think with more usage hopefully will open up a bit. My question is i dont see the solenoid to be servicable does anyone recommend a drop of oil inside the spool section or anything from the top or know of a way to remove the spool inside the solenoid grease or change seals.

I know there some modifications to take a lv2 solenoid/manifold and dremmel some grooves just trying to avoid spending around 300 dollars canadian.
