What should the charges be to replace a cam in a B&S Intek 18.5 HP powering a Craftsman rider ?? The starter wont turn the engine over. I am hoping it is just a valve adjustment however lately I have been reading on this forum where the lobe on the cam has been found to be worn on this engine.

Hello, I have an older model Lesco 36" walkbehind that I bought used several years ago from a good and reputable grounds keeping company, it's a right fine machine. But there's been a few issues in the transmission, that I think need to be fixed now. For the pertinent details it is labeled as a "[B]Peerless 2346 7996[/B]" and "[B]Tecumseh 3628-P1[/B]" googling those numbers yielded me nothing. It is a [B]5 speed + reverse[/B] transmission/gearbox. Now here is my problem; the gears/speeds 1-3-4 do not work, that is to say that when the mower is running, I put the control to that speed setting, and the transmission shaft will yes turn, but there's not enough power in the shaft to actually get the belt-pulleys//wheels to move. Reverse- 2 and 5 work well. But 5 is too fast for me without a sulky. Now I'm including photos, as you can see there's grease leakage from the right shaft that began about 3 years ago, my local shop said not to worry, just to keep the gearbox filled with grease. That is exactly what I've been doing, but that doesn't fix the fact that the 3 most needed speed setting don't work on this transmission. It's very frustrating. I'm moderately mechanically inclined so I'd rather fix this than have to replace the transmission. My local shop again quoted me about $350.00 for a new one and didn't want to quote for a repair saying that once these types of gearboxes begin "slipping" that they're ruined, I'm not so certain about that. So I'd rather save where I can do some of my own work on it, you know? So, does anyone here have any ideas what might be the problem and what the fix might be? I hope it's something stupidly simple. Please?:p I'd appreciate any help on this ongoing problem. Thanks.
