RE: Old Cox .010
Ubird,
I would suggest you contact Tim Wiltse here on the forum and ask him. Tim handles all of my Cox engines and does a great job on them. I'm sure he can fix your ittybitty engine. He has a website but if you just do a search on Tim here in this forum I'm sure he will pop up.
good luck... I love my small ones...
