Default Re: Nozzle spray angle...

Chemist here.
Water and methanol mix in any ratio and are fully soluble in each other. It turns hot when you mix water and methanol. That is normal. There is no formation of any insuluble components unless the methanol or the water contains impurities.
As mention before, hydrocarbons, i.e. a wax, are the most likely contaminats in your case.
Shorter chained hydrocarbons from a petrol additive would be liquid at room temperature and float as droplets on the surface after some time.

I'd look for a better methanol.
I have used Efoy fuel cell methanoi.

For the indicated AFR of you wideband, tune for 12-12.5:1 (petrol equivalent) = lambda 0.8-0.85
If you run much richer you lose a lot of power.
You will also need sufficient ingnition advance. The mix burns a tad slower than pure petrol.
