Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I sent a message to Jin asking him to reply and he did. I told him I heard you had an updated camshaft for the R31. So waiting on a response.

You’re the man! You’ve given me nothing but good advice! The engines love the new fuel mix.

Have you noticed the floating wrist pins have no retainer so the pin comes out and scores the cylinder wall? Just wondering what your fix is for this bugga boo.
