I've looked, but found nothing so far.

There's got to be a step-by-step instruction set on the internet on how to tune an engine properly from totally not running/completely out of adjustment, to running nice and reliable. It'd be nice if there were pointers on knowing when to change glowplug types/heat ranges and troubleshooting.

I'd love to build a page for everyone, but I'm learning myself. One guy swears by an OS#8 and another by an idle bar plug and another by an OS A3 and an OS A5..... what the? How do you know besides trial and error? At some point the engine manual is useless especially for a perfectly good older engine like I have. I've got advice, but it's just what has worked on my application. The same advice didn't work on a buddy's OS .46 that was doing EXACTLY the same thing mine used to do.

It sucks that you just try stuff till you find what works. It costs a lot of time and money.
