    ok guys i have a makita chainsaw and when i was replacing the clutch i got the cylinder head stuck. I found on a website on how to replace the clutch and they told me to put nylon rope in the sparkplug hole to jam up the cylinder head. Well i did it and it work i was able to replace the clutch and now the head is stuck. When i got the nylon rope out i saw that some rope was still jammed up in there.

    My question is whats the best way to knock that cylinder head loose? Ive gotten a hammer and put some wood in the sparkplug hole to try and hit it out. Do i need too just hit harder or is there some tricks i need to know.

    i don't have much experience with this and i can use all the help i can get

    I dont know how the heck you could get it stuck that way but I would say your gonna have to pull the cylinder off. Dont know how hard you should be hitting the piston.

    You probably have the rope jammed between the piston and the exhaust port. Possibly the intake. Remove the muffler and remove the fibers of the rope so they don’t get stuck in the cylinder.

    alright well i took the muffler off and Diamond was right. The nylon fibers were jammed between the cylinder and the exuast port. I was able to get some of it out, but its still jammed up in there.

    My question is how do i get the rest of the fibers out so that the cylinder will be free?

    I have tried hitting the cylinder head through the spark plug with a hammer and a piece of wood, but it still won't budge. is there a trick i need to know?

    Any help would be greatly appreciated.

    Just pull of the cylinder and clean it out. Thats the only way you are gonna get all the crap out of there.
