Problems with newly built DJ engine

[ajsimmo]

Well, the increasingly bad running of the engine turned out to have a rather silly cause: my own inaccuracy. After having set the basic valve preload during assembly, I failed to tighten the locking nuts on the tappet adjuster screws of cylinders 3 & 4... Now the engine's running fine again.
Thank you all for your input.

Thanks for the update, and kudos for fessing up. Glad it was an easy fix
