The shaft in my FJ45's distributor snaped . The brand new replacement distriutor doesn't adjust properly. Lots of back firing. I have removed and maticulously refitted it three times. I am unable to set it to run smoothly/properly. Please help?
Distributer swop.

May the force be with you?
The rotor should point at #4 plug when TDC on compression #1 cylinder. Due to the helical gear the shaft rotates as it seats - very easy to be one tooth off. Second is you must engage the oil pump as the dizzy fully seats.

I find it easier to use a remote starter switch while pressing down on the dizzy to rotate the engine to get the shaft to pick up the oil pump - you will feel it drop in - then tighten the dizzy clamp. Verify you have oil pressure before running it for very long.

And it’s fairly easy to get “180 degrees out”, meaning you stabbed the distributor when #1 piston is on the exhaust stroke NOT #1 at TDC. (The flywheel still lines up.. but is lying to you! 
). Once stabbed 180 out you can try to time it until it runs poorly and backfires (as I recall, I know I have done that on SOME engine(s). Best to stab distributor with valve cover off so you can see valves and confirm compression stroke. It is the first thing I check if I’m going for a rescue… SA is a bit far!

This. Remember, you have to rotate the crankshaft TWICE to make the dizzy rotor turn ONE complete rotation. So there are two TDCs. You have to find the right one.

A hearty "THANK YOU", from me for all the help, support and encouragement I received from you guys. I went through the process again (a forth time) and yes, I was one tooth out. The Hulk now runs as good as the best it has run in the past. Sweet as a nut. I couldn't have done it without you. Thank you all, once again.
