It is very close.
Chill the brass thermo in the fridge for about 20 minutes to get the temp below 20C. measure the length of the thermo.
Then with some boiling water on the stove,check the water temp. it wants to 80C. Immerse the thermo by dangling it in the water on a piece of wire. it doesn't matter how long it's in there for, about 5 minutes should be sufficient.

measure the length again.
if it has moved completely it's OK.
When checking the injection,always do the basics FIRST.
A perfect ignition and valve lash are more importantr than messing with the injection.
You should also have at least two sets of plugs handy. You can quickly clean sooty ones and replace the plugs to ensure your engine is running properly and not just missing because of fouled up plugs.
