I haven't looked for carb parts yet (i'm just getting into the Lazair game as I'm finally almost done rebuilding 2 of them) but I've got a shop in the states set up to make brand new head and base gaskets at about $10US for head and $7US for base. Other than that, just general scrounging for parts and old engines.
On the few flights that i've done, looks like i'll get just shy of 2 hours to fuel exhaustion on 5.5gal, and that's a heavy plane and a heavy pilot (series III at 300 pounds and me at 270 pounds).
