I would simply rethread it for a readily available hex socket head screw size, making sure to square up the tip and use a center drill to hollow the tip. Sounds like a fun day though.
Already been sent off for attention, but the hex socket head sounds like a workable approach if it happens again to one of my engines.
It was great to be playing with diesels again. I was particularly impressed with Steve's Olly clone. I'll have to look into getting one of the CS ones myself.
My wife was rather unimpressed with the characteristic odor of diesel operation 'though. She's only been exposed to glow power up to now.
One more question :-
When my MARZ was running, I noticed that the needle valve was rotating a bit from the vibration. Fine for bench running, but I need to find a way to secure it for flying. Thread tape the best way to do deal to this?
