Any chance you could post some photos?

hi again,  I got some more pics and got it running now. It was spitting sparks big time i think the rings might have been stuck because after i left the cylinder to soak in wd40 it stopped the sparks that was comeing out of the exhaust.  It also lost all the oil twice but now seems ok.  Running out of oil did not do the ends any good!!! whoops lol.  I had a problem with one of the idler pullys on the main belt and because i cant quote them a number because the machine is no longer made, without the part number no one would take the trouble to look and match the old part with the bins full of pulleys that would fit my machine!!!!!!!  progress they call it!!!!!!!.  Any way i split the old one in half and replaced the rusted lump that was in the centre with a  new bearing and welded it back together, it works fine now.  As you can see i have taken off the deck and grass chute, i want to alter the chute so i dont have to take off the rear axle each time.  I was surprised to find the axle was going through the discharge chute, that meant it was one huge solid ball of dried grass etc that would have readuced to flow and made the thing work harder because it was binding. Anyway  now that i have it working i will be giveing it a paint job when i have the time, and a new drive belt because of the bits that the idler had chewed from it.  Hope you like the pics   Charlie
