Thermal Hopper twin needle
Hi all, i'm Francesco, from Italy, i'm collecting cox engines after found a medallion 0.9 in a box sleeping by 25yrs
i just bought this beauty thermal hopper, good conditions, good compression, probably polished by seller or prev owner, i try to start it, but it does few fires and not runs...i opened it to clean and i didn't found any gasket between cranckcase and rear plate and reed valve not close good.
- someone knows as disassembly reed valve? it is locked
- someone can do a picture of it in good condition?i would check if mine is damaged or flexed or other
- someone has a wrench / prop/ rear bid cage or other parts unuseful to sell?
thanks in advance for all your helps and sorry for my poor english

Wow that is pretty dirty looking , but not stuck ! The thin reed goes in First then second reed , Top retainer (note slot ) MAKE SURE THE RETAINER FITS SNUG if not when running it will come off and destroy it
