Hi all this is my first build and first post. So here we go. It all started out when I found this old engine from a 1974 weed wacker. The engine is a Tecumseh 85cc 3 hp. It also has a scary looking weed zombie on it which is pretty cool.
Sorry the image is upside down.
So I got the bike all built up with a back rack, chain tensioner and hand made clam shell adapter.
I have a 42 tooth gear on the bottom and an 11 tooth gear on the engine. I was so happy and ready to go. But it was not meant to be. I fired it up and i wont move, the engine runs good with the chain disconnected but as soon as a load is put on it it just does not move. If i lift the tire up it will spin it really fast and i lost a chain that way and destroyed it.
In the early stages of this build I was an idiot and started the engine with the bell housing off the clutch pads. You can imagine what happed clutch pads and springs went flying. I found the pads but the springs were shot. I went to ACE hardware and purchased some music wire, which is spring steel. I bent my own springs and put everything back together. The output shaft does move a little more at idle that it did before the mishap but the bike will still not move.
I am at a loss. Is it a clutch problem or is the engine really that week? Should I ditch the clutch and just direct drive it, i would have to kill the engine at stop lights then. Or should I get a different engine. I am confused, please help anyone.
