Grump,
watching this thread with great interest as too, am going to do the same in 6 months, when winter turns up.(Aussie)
Good luck digger.
Baloffski.

 

Thanks Bluehighways - kinda figured that wasn't the best way to get them off - BUT it would make for a interesting adventure. Baloffski1 - stay tune and I'll give you an update. Plan on working on them this coming weekend.

 

Those who said "they come right off" were correct. One took a slight prying between the cylinder and the head (in the area around in the intake port) but they came off with no problems. Thanks to those who replied
