Does anyone know of a way to tighten the timing belt without pulling the engine and flywheel on a honda 3813 riding lawn mower. I know to tighten the belt you loosen the water pump and move it, but the bolts for doing that seem to be under the flywheel.
Thanks for the support bwd. I am going to try a few things tonight i will let you know how i come out.
Has anyone ever set the time by using the T mark on the flywheel. I am also going to try that, i found a mark just to the lower right of the water pump, triangle shaped just like the one on the block i think is the line up mark. I have been setting it to top dead center and i think that is not right. I will find all this out if i would quit being lazy and pull the engine.
So far i have not figured out how to adjust the timing belt tension without pulling the engine. I did time it with the mark on the flywheel instead of top dead center and it ran much better. The carburetor is the problem it is flooding i have been through it no less than 4 times i dont see a problem. It was a little sluggish to crank i thought the timing was off . I installed a fuel cut off valve in the line and now it fires right up with the fuel off just with whats in the carb but after its been running for a while it surges and ever so often a puff of black smoke comes out the exhaust. I think i may have to buy a new carburetor.
