Could that be brought on by diesel washing the bores and diluting the oil?
I used to work with a Korean chippy who had one of the wood block planes you pull towards you. He would often be up sharpening it till 2 in the morning till he got an edge you could shave with.They're a bugger to sharpen properly.
Update.... unfortunatly today when I was cleaning I found that there is quite a bit of play in the turbine... so... guess I'll be replacing that.
Oh well.. shit happens. But any Australians on here heard or used Munro racing turbos? They do a upgrade/rebuild for exchange for the ct26.. for about $800
Looks the goods and by far the cheapest option I've found so far
Was that the one you fitted Dervis? Looks comprehensive with all the springs and set up info.
