    I thought I'd use brake cleaner to cc some heads but it washed the markings off my cheapo syringe. :rolleyes:

  3. Its a great book. Read it virtually cover to cover. You won't understand all of it, but enough will sink in that you can then use it as a reference. Worked for me anyway :thumbsup:

  4. looks like I’ll need to buy a dial gauge for the end play a deck height measuring tool and a combustion chamber measuring kit

    as I read and look at you tube I’m struggling to understand why I have spacers in my combustion chambers should these not be removed and spacers put between the cylinder and the block? Or am I missing something?
     
  5. Are they head gaskets? If so they aren't necessary, but removal will affect your deck height.

    I measured the combustion chamber diameter and ordered a plastic disc to suit off ebay and drilled a hole in it. Then use any old syringe to add fluid until all the bubbles are gone.

    For now grab the flywheel, push and pull. It should move but only just perceptibly and you might hear or feel a dull clunk. That would be encouraging.

    If it moved 1mm+, that's not good.

  7. No they aren’t head gaskets they are inside the combustion chamber

  8. If that’s accurate enough that’s great I’ll do that but the spacer ring in the chamber will alter the CC - won’t it?
     
  9. Yeah, take the rings out you d8nt want them in there for measuring or afterwards, spacers go back between cylinder and case later to adjust

  10. Thanks Deefer

    I’m going to slow down and do it properly rather than rush to rebuild because I’m in no hurry and might as well do it right :thumbsup:

  15. Hi all just a quickie this morning I was given an ultrasonic cleaner which the boy had never used and had no idea what solution is best to use for engine components ?

    Any recommendations appreciated

    cheers
