Hi Dave,

So this weekend I went with the Tetra tank, things are slightly better, also found that the one way valve was a little loose. Unfortunately, the motor is still not running right. I can start it ok, adjust the high needle for slightly below peak and all seems to run normally for a minute or so, transitions from idle to high throttle beautifully. Then the rpms start going up and down. At this point going from idle to full throttle, the engine will turn about 3000rpm then take about 30 seconds or so to throttle up, or just bog down and quit. Engine can't be restarted until it is cool and I release pressure.

You may recall that my problems started with a very small "pebble" in the regulator. I'm tempted to replace the diaphragm, but on the other hand I've gone through a gallon of fuel tweaking all the adjustments and want to send the motor back for servicing, especially since you mentioned in another thread that one could replace stuff left and right and not get closer and that your staff are experts.
