"I have the head off. The precombustion chamber will not just slip out of injector hole. There are carbon deposits.
How do I "dissolve" or otherwise remove carbon to get the chamber out? Is it safe to tap the chamber "nose" that sticks out of the head between the valves, maybe with a piece of wood?
The exploded drawing of the injector in my Clymer manual (Fig. 23) shows a "gasket" and "heat shield." I have a new yanmar part called an "insulator", but it does not look like the "heat shield", which in the head has a copper wafer top. Is the copper wafer top, the "gasket?" If so, I do not have that part and any recommendations about where to get it will be much appreciated.
Thanks,
