RE: Ryobi tuning help
Gave it another try last night. Set needles back to 2 turns open apiece. Choked engine, set throttle to WOT and flipped until the engine sputtered. Open choke and flip, engine starts and runs full blast for about a second or two. Just long enough to burn the fuel from being choked. Choke again. Same results. At about this time, it stopped firing at all. Discovered that my hall sensor had come loose. I had used epoxy to glue it to a hose clamp then mounted to crankcase. Epoxy broke loose. I had debated on drilling and tapping the crankcase but did not want to remove the crankshaft to do it. Decided to give the epoxy one more try. So set it up to cure overnight.
In the meantime, I noticed that my throttle plate had not been opening all the way. When I get to 1/2 on my transmitter, the servo had reached its end point and the throttle was only about 1/2 to 3/4 open. I did not get the servo arm back in the right place. Was in too big of a hurry. So when I was trying to adjust the H needle last time and was not getting any response it was because the throttle was not fully open. My fault again. [:@] Problem is on the Ryobi, the throttle arm and plate are hidden between the muffler and carb and is hard to see. To say the least, I spent some time last night making sure it was set correctly and that I got full travel on the throttle. Now if Ike will just hold off a little longer, I will try it again tonight. If not, rain until Monday.
