2000 Sportster LX Engine Questions

[Andymac]

Hi All,

I have a couple of questions for the forum.

1.  Just bought a 2000 Sportster and was looking at the engine for a serial number and found a Remanufactures SN:  Y236041.  Anyone know how to decipher this.  I am just trying to figure out what the actual engine is so that I can get the right parts.  I have been all over the web trying to identify the exact engine model, but I can't figure it out.  Anyone have any ideas?

2.  Boat fires in the intake manifold on initial acceleration and occasionally while running at speed.  Carb was replaces just prior to my purchase.  Anyone have any ideas what may be causing it, and what the fix would be?

 

Thanks

Take a picture of it.  Although 99% sure it is going to be a Chevy 350.  The only thing that should really matter in terms of parts is identifying the type of ignition and the type of raw water pump.

Lots of possibilities here.  I would start with a complete tune up, including plug wires in addition to all of the regular stuff.  No sense chasing a gremlin if you don't start with parts in good condition.

Agreed.  I'd do a tune up and based on the description check the timing.

I would look at the distributor cap, corrosion could contribute to crossfiring which would be the intake pops.

You might want to verify carb is marine compatible.
