while searching for the cause of the incessent popping in my carbs, i decided to check my valves. turns out the adjustment screw for the # 4 exhaust is MISSING. i don't know how i did this having adjusted the valves last year before installing the engine. also the nuts on the rest of the rocker assembly are not 13mm , they are larger and possibly american. what the hell do i have here and can i replace the #4 exhaust screw or do i have to pull out the whole assembly.

It CAN get into the engine via the oil return slots for oil in the pushrod tubes..
the larger 10mm adjusters use a 14mm hex, not a 13. This is why these are TORQUED every time they are tightened.. They will come loose if given the opportunity. |
