I think you may be confusing firing order with position. Generally cylinders are numbered 1 to n (where n is the total number) from front to rear, so on a Puma no.2 cylinder is the one between 1 and 3, second from the front. The fact that it is the third cylinder to fire during a full, four stroke cycle, is irrelevant. |

I will shortly be continuing on with my strip down, however I believe that an inlet valve may be stuck open. There is ‘smoke’ coming from the inlet when cranking for the test. Has anyone come across this before? I can’t find anything online relating to Puma engines and intake valve problems.
The third cylinder back is cylinder three. The 1324 is the firing order not the cylinder order. |
