Hi,

my engine needs a new head because the head muffler connection threads have slipped. Plus I need head screws. OS went for an odd size of 3.5mm for these engines and these arent available locally. I will need to get those from OS as well. With a FS72a, a FS91 running and another FS91SII, FS110A, 65ax, 95ax and 120ax sitting in the box (those are just the glow engines I have), there was no point trying to restore this one. Thats why the gas conversion question. But with a blown head and no easy way to convert to gas, there is not much point in the gas conversion either.

By the way, the engine has a neoprene seal o-ring in the carb and the HSN. Wont those need to be replaced if I run gas in it?
