The truth, that the initial question should be whether the engine was working before disassembling or not.
If it was working, it would have to do, in agreement with the others, if you have problems with the captor, and if the new pinion has the corresponding drafts for the signal of the captor.
If you had a broken tooth on the pinon, it is generally not so significant and probably the engine will work the same, of course the damage to the strap increased by the damaged edges.
Now, if you changed the strap because it was cut, it is most likely that you have caught valves, that engine, even what you are interferent ...
no matter how much it leaves it well draft and everything, do not start until solutions the damage to the butt, in the best case, and of pistons in the worst case
