Triumph GT6 - GT6 missfire
|My 1974 GT6 MKIII has developed a missfire but only on right hand bends. I have checked the floats, diaphragms needles, choke assy, fuel pump & filters (mine has a facet electric pump with regulator-checked them too!)mixture, timing & engine electrics, and can't find anything wrong. I have tried raising and lowering the float heights to see if that makes any difference, but it feels like it's not getting enough fuel. I have even lifted the right side of the car to see if the floats are shutting of with a fuel surge but it runs perfectly, even at a ridiculous angle. The car otherwise runs perfectly but this problem won't go away. Somebody please give me a clue, it's hard work going left all the time!|
|A sudden missfire hat corrects istslef again is probably electrical, rather than fuelling. You have excluded the usual fuelling causes anyway!|
Check all the connections and for worn insulation in the igniton circuits, low voltage first.
|I have heard of a similar case. It was caused by a faulty earth lead which should run between the engine and the chassis. On my GT6 it runs to the bulkhead.|
Check it out, you never know!
Norbo has offered you another cause - what happened? Please feedback.
