Hi,

One of the things discussed when we were looking at the engine, was whether the fuel nipple threads went in far enough to block the the hole partially. Don measured the length of the threads and the depth of the hole with calipers - it appears to have lots of clearance below the threads.

As far as the turbulance of the fuel flow, I took another look at post 95 and noticed the hole in the brass insert was away from the carb throat. This means the fuel would have to go into the fuel nipple then be drawn away from the carb throat before entering the hole and going to the carb - I don't know much about fluid dynamics, could this create a problem? If so, the hole I drilled into the brass insert would have taken care of this and allowed the fuel to go straight from the fuel input nipple into the brass insert drilled hole.

I looked at the macoa site and in particular the fuel leaking through the front bearing. Thanks for the link.

Look forward to your next step.
