i bought an older gardenway troybilt tiller 6hp tecumseh. i am trying to bring it back to life. had no sparkplug just some kind of offwhite gunk plugging the hole. i took the head off. cleaned it all off. cleaned some minor buildup at the top of cylinder wall. changed oil, new sparkplug. cleaned off magneto. has a carb. leak right now. tries to start has nice bright blue spark but didn't try to start. next is to put carb kit in. it doesn't seem in bad condition at all if it has really set up as many years at the man told me i bought it from. it does need two new tires, old ones are totally rotten. i really can't see a pin to remove the wheels as i have been told. i have thought about cutting off the old tires and putting on the tire & tube on the machine. oh by the way i paid $65 for this my first troybilt. i may post a pic on here sometime if that is possible. i do have a good craftsman front tine tiller, but i have wanted one of these for years and thought this is my opportunity. as other have said these older ones are probably built better than the new ones.
