I purchased a beautifully converted short-shaft ryobi second hand that seems to be in great condition-but that I never saw run. Unfortunately, it will not start for me. Here are the symptoms:
It draws fuel with the throttle open and the choke on;
It will pop if I squirt some carb cleaner (ether) in the crankcase but the engine will not run for more than a few seconds;
I can get it to "run" with the choke fully on, but it runs very, very rich (so rich that the throttle does not change the speed of the engine;
I am using coleman fuel mixed 32:1 (which works just fine on my real weed wacker and homelite blower);
The carb diaphrams looks nice and clean to me;
I've tried resetting the spark plug gap and used several plugs;
I've reset magneto gap and I can see a nice spark with the plug out and grounded on the crankcase;
I'm using a standard starter w/ 19.2 volts that starts my other Ryobi conversion;
I've tried various needle settings, but I've test multiple times at settings between 1 and 2 turns.
OK conversion gurus...what gives and what should I look for?
