Default RE: Ryobi tuning help

Since what is left of Ike is blowing hard outside right now, I decided to pull the carb off and go through it. I bought a repair kit yesterday. First thing I checked is the pump. All good. Next I took the regulator cover off and discovered that a too thick gasket was used under the diagphram. Next I pulled the needle out and found that the red was showing on the needle. Needs replacing. Then I shot carb cleaner through the needle openings and found that I had good fuel flow from the idle and high speed ports. This carb has the membrane check valve and it seemed to be working ok. It would bet wet but not allow a bunch of cleaner through when cleaner was shot through the needle ports. So I put a new needle in. Changed out the gasket on the diagphram. And then put back on the carb back on the engine. It should be good to go now. I think part of my problem was the bad needle and the wrong gasket on the diagphram. I also read on a web article that the diagphram should go on the body first then the gasket then the cover. So that is the way I did it. Made double sure the throttle was set up properly on the servo. Ike looks like will be out of the area by tommorrow afternoon so hope to try again then. I have learned a lot about how these carbs work over the last week. If I had known sooner, I might have saved myself some trouble. Most of it was my own fault.
