Possible blocked injector

[matthg40]

What is the best and safest way to check if I have a blocked injector very random question but there is always method in my madness 😬 also I red something about removing the resistor from my rotary arm as I think my g is still detonating after setting the timing after the rebuild so still in the process of setting her up.

Color of spark plug is usually the easiest way to know if one cylinder is leaning out. There are plenty of pictures to compare on the interwebs.

Nice one dude I had I look in my Haynes yesterday just wondered if there was a more in depth suggestion I’ll check this morning

Swap it with another one and see if the issue moves. You got a laser thermometer? You can point that at your exhaust headers and see if there's a difference in temperature (cold one compared to the others = not working properly)
