Yes, I would attempt to start the engine in a test tank/barrel. An engine with sloppy wrist pins/bushing/bearings will tick at idle…The noise will go away if the throttle is raised a bit…I’m not sure if you engine has plain wrist pin bushings or actual needle bearings. The 10hp engines with plain wrist pin bushings are known for wear issues…Your FD11 has wrist pin needle bearings, I have never heard of any issues with them….
Let us know what you think when you run the engine, I wouldn’t pull the exhaust cover, leave the intake bypass covers in place also…
Have you done a compression test on this engine?
At this point, I am not convinced you have any issues with wrist pin bearings…
