Wrong way around Cobba. Negative wire into the needle. If possible also use high current. 10-15A or higher.Will have another play with the air cleaner housing tomorrow after work. Also got the electrolysis set up with the positive connected to the needle so will switch that on tomorrow as well.
Cobbadog, washing soda from the supermarket is what you want at Coles $4.00 a 1 kg bag (Lectric washing soda) is its actual name on the bag, I will attach a file re electrolysis for rust removal good reading.Going into town tomorrow Scotty to buy some soda ash and try again with the charging of particles in the tank (ice cream container).
Like Dobbo our supplier of rings is waiting for his delivery from N.Z. who have gone back to work so maybe they will arrive soon. I have also asked the same supplier about a pair of valves for the McDonald and have sent him some sizes and hopefully he has some blanks to suit. Old valve stems are showing a heap of wear so if some good valves can be had this will help the engine when it's time to run. Cam gear should be ready so I will give him a call tomorrow as well then I have to consider making the fuel tank along the same lines as the air cleaner but I will try to be not as rough this time, but it does add character.
