Here's a question for all you hardcore Ryobi vets. Once you get your engines set up and tuned and running well the way you like them (idle, top end, transition, etc.) do you find that you can leave them alone and not have to be turning needles every time you go to fly and the weather's a bit different or do you have to tune a bit every time you fly? I've been flying Ryobis for a few years now and it seems that more times than not I have to give the high speed needle a little nudge one way or the other to be goodon any particular day. Once done I'm good for the day. The reason Iask is up until now the needles have been very accessibleon any installation I've done. The next plane I'll be assembling and using Ryobi powerwill be a Gee Bee R2 and with the massive round cowl that's not easy to remove and thecarb right in the center of it behind the engine I'm kinda scratching my head as to how I'll do any quicktuning on a day to day sort of basis.Are all of these enginesa bit sensitive to weather or is it just mine?My string trimmers alwaysseem to run just fine without ever tuning them atall but I definitely don't ask as much from them asI do my airplane hot rods. If regular retuning is the norm does anyone have any good ideas how I can make that happen on my Gee Bee project? If it's not the norm them does anyone have any good ideas why I seem tobe doing it all the time?...
