Had another play with the 3 wheeled BMW thing today. They've been trying to start it with out success. I get there and I can see petrol dripping out of an exhaust joint where the front pipes meet the silencer.
Flooded I suspect.
It seems the previous owner, who put it together, had a petrol tank leak and opted for one of these tank sealing kits. Don't think it got on to well with our new petrol as it seems to have softened again and gone through the whole system gumming up the injectors as they now drip with out power.
Then back to the shed. Still trying to get that bloody shock to bits and make a throttle/oil pump cable out of the old one and a new which as usual was nothing like the original.
