Hi all - first time asker...
I have a riding lawn mower with an 18.5 OHV B+S engine... the engine has about 14 hours on it so far (over a few years of low use)... I was running it for a few hours today and noticed some smoke from the engine a couple hours into it. After running the engine under load (mower deck close to the ground), I noticed more blue smoke.
I tried to shut down the engine (turned off the key, throttled down all the way and even got off the mower (with a seat safety switch) and the engine ran for another 30-45 seconds, giving off a heavy blue smoke. After the engine shut down and cooled a bit (seemed to be running hot), I checked the oil and it was still in the OK range (on the low end).
I changed the oil and ran it a bit... blue smoke when throttling down or up and also when under a little load (such as simply in drive on level ground).
Any thoughts on what it could be? Also, any thoughts on the level of difficulty for self-repair (mechanically inclined electrician / machinist but never tried small engines!)
Thanks in advance!
