Having finished work for Christmas I have been using some of my time wisely getting the chrome parts ready to be sent away to be sorted. When I stripped the exhaust down I discovered the source of the really rubbish running all those moons ago before it was taken apart.
With a bit (read a lot) of persuasion I managed to get the baffle out.

hmm there's quite a lot of crap coming out of this exhaust....
Get it all the way out to be greeted by this

The baffle is packed solid with carbon/oily deposits.
No wonder it wouldnt run right there's nowhere for the exhaust gases to go!
Got it soaking in some wd40 to loosen it up the I can try clean it out.
Anybody with 2 stroke experience, is this just a sign of a neglected exhaust/ something that two strokes do, or is it a sign of other problems?
Now I've got the special tools the next job is splitting the engine
