Hi guys
I have an old Echo gas shr200e backpack sprayer and it looks like that( http://myrtlebeach.craigslist.org/grd/1247627091.html )it is a two stroke engine and i see some people converting these type engines for rc flying so i also want to convert that engine for airplane i also do some tests and run a 18 *6 propeller and it gives me about 4 to 5 kg of thrust and it weights about 1600 grams but the problem is that it have a reservoir carburetor and it can not suck the fuel and to run the engine i have to mount the fuel tank 4 to 5 inches above the engine so if any one of you knows how to modify the carburetor for this purpose so reply me
