Guy gave me a lawnboy mower ,..rear drive. 4.5 hp. Tuckcumish .. Float was bad so I ordered a new carb off the interscreen....$11.50..I was skeptical ,..figured it would be hollow it was so cheap!! Well I bolted it on and varooom!! started right up! Mowed the whole lawn with it,..never missed a beat. So swallow your pride and buy one,..it worked for me...
