help i think i spun a rod bearing on my m2 jet drive 210
was runnig just fine then started cut out (kinda like water in fuel)
then ran fine for awhile them lost RPMs at wot.them stoped
restarted (sounded kinda stiff while cranking) let it idel for a while (10 min. )
then wot. for 2 min. then it started to knock !! it will still start an idel
can this be a rod bearing? can this motor be rebuilt?

It could be a rod bearing, but before we jump to that conclusion lets do a couple of checks.

A cylinder that is misfiring badly could sound and act like a rod problem, so start by pulling the plugs and having a look at them. If they look fairly old replace them and check the plug wires while you're at it. Before you put the new plugs in do a compression test on all the cylinders. If one is more than 15 psi below the others you may have a problem. Before panicking though be sure to spray some of your two-stroke oil in the cylinder and recheck it. If the plug was shot the compression may read falsely low due to being washed down.

Start here and get back to me.

No problem, but talk about bad timing...............:ack:

Have l look at it first thing on Sunday morning and if it's something simple you may still have time to save the deal.
