I was referring to the plastic line that one uses in a string trimmer, such as Weedeater, Stihl, Echo, etc. It is sold in rolls, and you cut off however much the trimmer will hold.

This line has the stiffness needed to clear out the drain blockage and yet is flexible enough to get past the turns in the plastic drain line.

I had this issue on my '94. I used some electrician's earth wire sleeving, which I was able to feed in a good couple of metres or so (IIRC). It was easier with the leading end cut at a 45 degree angle.

But actually, it turned out not to be the drain holes at all. If you remove the front black plastic corner pieces, you will see a foam rubber seal. This deteriorates with age and lets the water through. I would suggest removing the front corners, cleaning everything, and re-sealing all the mating surfaces with clear silicone. Hopefully that should fix your problem.

The green circle is where I'm talking about. (In the red ellipse is what looks like a crack, but isn't.)
