Changed the fuel filler elbow and found a 5mm split in it. Probably reponsible for a smell after filling ip. Changed all the breather connections in the engine bay using 5.5 mm fuel injection hose. In the end they all went on although I was bleeding. Changed the primary main and primary air on the carb to see if it was going to make a difference. When I turned the carb over yellow oily stuff not petrol came out of the primary air jet and emulsion stack and out the primary main along with petrol..... strange .... Decided to check over where I got to with the K-jetronic FI back in March before I had to rebuild an engine instead. Found all the bits were still in the box. Cleaned the bus. Went for a drive and an ice cream at Weston Shore. The queue at the ice cream van in front of us evaporated when the guy selling the ice cream refused to tell a customer which was his cheapest ice cream. He told him to read the prices on the side if the van. About three families and a million kids walked off in solidarity. No wait for us..
