Guys... two of my RedMax units are giving me problems. A pair of hedge clippers and a blower. I've done nothing yet to try to figure out either other than dump the fuel. The hedge clippers just do not seem to want to open up on top end. But if the tank is pretty low and I tilt them to one side full throttle... Well then the engine opens up and runs like I think it should for a few seconds. Then it dies. This is the only way it dies though. The blower on the other hand, I noticed started with that "tinging" sound like they do before they run out of fuel. Shut it off to refill but it wasn't 'that low'. Later on, now it is to where it will run fine until you full-throttle it. Once you hold it full throttle just a bit, it will choke all the way down and die if you don't let off the throttle. Otherwise it will run. Any ideas?
