RE: Glow Plug worries
I can't attest to the truth of the following, but here is a quote from a review of a made in China Leo 37:
"The engine was supplied in a plain white cardboard box. Inside we find the engine and silencer, a double A4 set of instructions, two open ended spanners, two allen keys and a Fireball glow plug!"
I can't see the Chinese importing glowplugs from the U.S.A.
