Gday Guys,
Thanks for the support so far, Tinman, Oldman ill have a play with the carby and see how it runs after work if its not too late. Ill get back to you with my findings. The exaust fell off when i was out 4x4ing and im already in the sh!t with the neighbours, sounds like a race car, loud and obnoxious! As for the carby, its the same one that came with the engine, nothing has changed since it ran good except for the power valve and new metering block/bowl gaskets!

Would moving the dizzy really matter? By moving the dizzy a tooth here or there your only changing the position of your rotor. This change would then be counterracted when you then twist the dizzy to time it correctly??? If my light shows 14 degrees, then its 14 degrees no matter where when dizzy is located, as long as the number one spark lead is in the right spot... can anyone clear this up for me... doin my head in LOL!

You're sorta correct the purpose of the ballast resistor is to limit the current in the ignition circuit. It increases the life of the points. Depending on the age of the vehicle this was achieved by a ballast resistor or a resistive cable (my old HZ has the resistive cable type). The resistor must be bypassed when using an electronic dizzy as they require a full 12 volts to operate.

Im not an expert but im pretty sure carby backfire is due to a lean condition, backfiring thru the
exhaust would be caused by over fuelling ?(correct me if im wrong)
Sorry for the long winded reply, got no jobs on here at the workshop!
