Zenoah G26. Test Run After Rebuild.

This is an old engine with some suspected crash damage. On the inside, it doesn't look like it ran a lot. The carb mounting screws and threads were damaged and the thread moldings felt like they are coming loose. So instead of re-tapping the threads, I decided to turn the carb and change the vacuum slot for the pumping action. Now it only uses the two main bolts and it works perfectly. The engine runs fine and it can still be leaned out a bit after some fly time.
