Screeching noise from eng? dry bearing? Brass(?) dust in oil?
12 HP Sumec eng. Made noise when new out of box. Thought was gen at 1st, now think its eng. Has about 5 tanks of gas thru it. Seems to run OK, really loud dry bearging - like noise comes and goes a little but is there most the time. CKed oil = lot of suspended metal in it. Looks brass colored.
Tag says 7SUMS . 3572GA EM
any parts available? Have not tore eng down, if can't get parts may as well run till flies apart?
Surely crank bearings are oil bath? What is in there that may sound like dry bearing?
Thanks for any help, insight,
