Hey CM, putting a "swirl" pattern will not be a problem, I can use a "cookie wheel" on my high speed angle grinder ( porting air tool with a 90* head). I have EVERY possible entrance to the engine hermetically sealed...even the oil feeds to the rockers, so cleaning that wont be an issue.
I talked to Bob from mie yesterday, he's read this thread. I COULD have gotten my parts drop shipped to me from Kioti...IF I was smart enough to call. I had talked to him before and led him to believe that I was gonna wait till after the 1st of the year, I THOUGHT I was gonna need a head.
THEN I figured out what the issue was, ordered through their website. He apologized to me ?? He didn't do A THING that required an apology !! The order time issue was induced by ME !....I now KNOW what to do the next time I need something from them...thanks to Bob !
As far as either being used...no I haven't...but WHY would it matter ? The either would be long evaporated before reassembly anyway
I use a strong carb cleaner for carbon, and brake cleaner for oil residues, AFTER hand scraping surfaces. Good old soap and water is STILL the best pre assy cleaner on the planet....drying with compressed air afterwards of course.
One HAS TO HAVE an array of blow gun configurations anyway, so ANYTHING and everything can get cleared out and dried......least thats what I was taught to do...especially after coming out of the hot tank.
Before I'm asked...I NEVER used a hot tank without TOTAL disassembly.. sure wish I still had access to one, and a CK10, surfacer, valve seat machine,main and rod bore hones, etc...VBG
Cooling is not an issue, I started out by making a grille guard 1st pic...THEN removed the battery from crammed up next to the condenser to out in front of the grille cover.
Then made a heavy bolt on steel ventilated cover for the battery now out front....nice weight too, like I need it with a loader ...LOL
