RE: Marz 2.5 Diesel opinions?
Hi Fiery,
I have that exact MK12B also new in box in much the same state as yours. The needle valve cup on mine is crimped on too "long" and the contra is tight as all bug, I mean tight as all get out,!of course.
I think mine is of similar vintage, 83 from memory as its packed away.
I believe the FAI free flight helicopter altitude record was powered by one of these.
Agreed that workmanship looks quite OK on these.
Have you run yours yet?
Regards,
DF
