I have a HP .61 that I recovered from an old helicopter; looks like it has never been run. It has Made in Austria on the side and serial number 01441 on one mounting flange. Also has a header pipe and super cool looking tuned pipe.
Engine body is black and head is gold (6 bolt).
carb is seized solid but will try to get it freed up with Kroil.
Any idea where to buy parts...need at least prop nut and washer (size?), and new glow plug (seems to be slightly smaller than my OS plugs), and may need to replace complete carb.
Any advice?
thanks
