Hi guys, I bought a Stockman,25K96,0774 13 hp Honda a few weeks ago,It hadn't run in many years I gathered. I'm just running the spanners over it and will use it this wet season as the push has turned into a 2 day affair now.Changed the engine oil and it fired up and is running well,took it for a run up the driveway where upon it shuddered and clunked every now and then,I thought it may have been the drive chain rusted or the tensioner as something was grabbing and releasing, today I took that wheel off,chain doesn't have any tight spots so I'm thinking something in the diff is off,maybe no lube is present.So thought I'd ask here before opening that up.There's a valve release? which comes out through the rim,which I'm thinking may release oil as i can't see any plugs for topping up oil or draining it.Nothing came out.So is this a straight forward job?Any special tools needed.Hours on gauge is 537 and lights and the rest of the mower looks to be quite ok.
regards
Colin
