Great info

Thanks for the conlcusion. I have just run OS and GMS and never encountered this before so was a bit scary mainly with the loud noise! Like I said above I think I have got it fixed and will just need to let it get run in now. Sure is a fidgety thing, lol. For the glow plug, the one in it right now is long, with an idle bar. What does that idle bar do exactly? Most plugs do not have them so it's curious to find one that does. I bought the os 8 plugs for a backup but did find they are slightly low when screwed into the head. I found if I put them on without a gasket, they seem to be darn close and should be ok . Will get some long ones when I can though. Tower website should take the word "long" out of their posting for the #8 [:@]

LOL. I am sorrry, I should have never mentioned this tiny thing as I can not describe it! Trying to use your terms.... I had been fidgeting a little with the piston rod and so had not seated it all the way back on the connecting rod. So, when turning over the engine they were not going through a fluid motion. Just opened up the back plate and seated it all the way on the connecting rods nipple.

Sorry for the confusion. I am good with lamens terms but with an engine and so many parts I rarely get the perfect name for things.
