strange ryobi behavior
#1
Good evening .
Tonight i ran converted ryobi on a test stand.It spun 18-6 at mere 7900 rpm.
But once i pick test stand nose up like 45 degrees engine start on running rough and slows down then die. Though at first it was too lean..So i started it and tuned this boy up.Raised the test stand to about 45 degrees up and it started bog down.I richened up needles as it started slowing down-no effect.
Next time i tried to lean them-still no effect.
The carburetor is inside of the engine mount (mount by wackerengines)so it covered from direct air flow.Anyone got any ideas?
Also another problem.My needles are vibrating out.I suspect it's unbalanced flywheel.What do you guys use to balance your flywheels?

Hi Mitty,
I would check to see that the pulse port is open all the way to the case. The pulse hole in the carb is next to the aluminum pump cover on the back of the carb. Also check for leaks which can cause the problem. Make sure that the fuel pickup is in gas you point it up. I balance my fly wheels with a Hi-point balancer. Any good machanical balancer would do. Do search on flywheel balancing or Wacker will balance them for $15.
