Need some parts information please- 5 hp garden tiller- think it's Magna- pull start won;t recoil- poor or no resistance on pull rope. We've had it apart down to where the ball bearings are and put those in place since they keep falling in. The spline seems to be magnetic. The shaft that fits on the spline turns freely and I think this is the problem. I'm wondering if this is some sort of sealed bearing and can be replaced? It's about three inches long. Don't have a manual on the tiller. There are four sort of cogs at the end of the shaft. They don't appear worn but not sure if these are what keeps the shaft from spinning or the inside has some magnetic property that it no longer has. Any suggestions? Thank you

Hello. I need to replace the fuel line (old one was brittle) to the fuel tank. There are 2 outlet ports in the fuel tank that have two different diameters. I was able to order parts through a local store but I do not know how to connect the check valve, vent fitting, vent plug, fuel strainer (goes in the fuel tank) and fuel line for these two fuel tank outlet ports. The parts list diagram at the store was no help nor was his young repair technician. Anybody know how to do this or have a diagram they can share? Thanks.
