RE: test stand for breaking in 56Jett
Hi Bobb
I got the engine to run steady at 17250 for a couple of tanks. Ran great starts right up and it screams like crazy. Blew a plug so I think more than 17000 at this stage is too lean. I fixed the foaming problem using lots of rubber foam and a bubbless clunk. It really worked. Scrapped the muffler on a hard landing but no serious damage. Thanks for the help
