I finally got a chance to thoroughly read Dennis Richey's article posted above and it is really awesome info.
Can anyone help me find tune this info into some type of procedure/guide? It may not be possible, but I sure would like to try.
1. Measure head clearance.
2. Based on head clearance, choose your nitro %: (Maybe thse should be ranges)
a) .36mm or less, use
??% nitro
b) .46mm or less, use 20% nitro
c)
.??mm or less, use 25% nitro
d) .56mm or less, use 30% nitro
If you need to use a higher or lower % nitro, add or remove shims.
3. Choose your glow plug:
And this is where the fun really starts...

Is the opposite true?
- When the ambient temperature is
low, we have to use a plug with
thinner wire.
- With
lower compression, we have to use a plug with
thinner wire.
- Humidity determines if we use a Cold (F) thermal range, or Hot (C) thermal range.
- With
low humidity percentage we should use a
Cold (F) thermal range plug.
- If we have
low temperature and
low humidity, we should use a plug with
thin wire and a
Cold(F) thermal range.
Now there is also this info:
At this point clutch setting and gearing play a role - not just the fuel, plug and head clearance. What are the troubleshooting steps before changing any of the above?

Go back to step 2 and adjust your head clearance
