If it weren't for bad luck........
« on: May 11, 2009, 04:51:58 AM »
Last week was rough.  I had to put down a Husky 50.  The engine was flat worn out and the bike is 9 years old.  I got the piston and jug back for the PW80 and the cylinder was cracked in the mail.  I tried to start my dad's '48 Mercury to no avail, the '73 Chevy convertible has a fuel leak.

On top of that, I got my '89 KX500 back together.  It has 110 psi compression.  I know... it's low... but acceptible.  It seems to get spark.  But even if I squirt ether into the carb, it won't start.  If I put a new clean plug in AND a squirt of ether it gives a poof.  Other than that and a couple of snorts as I was giving it a few primer kicks and it seems dead as a door nail.

I pull the plug and.... god I hate to think it.... but it almost seems like it's wet with coolant.  The engine has never run since I put it together.  Is this possible?  Where would I look for the leak?

New gasket:  check.

Torqued to spec:  wazzat???

Can't get a torque wrench on all the bolts.  But they is tight!

torque the headbolts to specifications ,
you assembled the motor just recently ,it was a top end job with the motor still in the frame i assume?

Pretty much a top end job with the motor in the frame.  Actually, I pieced the engine together from a mish mash of used parts.  I just want to get it running so I can sell it.

most of the time when they are that hard to start it is because the crankcase is full of fuel and it is way flooded. in that case a pull start is easiest.

if you "think" it is coolant then drain the coolant out of the bike and try to start it. if the plug is still wet then you know it is fuel.

be sure to top the coolant off before you ride the bike.  :-D

Most excellent idea.  I even have another carb I can toss on.
