Impregacy's "Moar" 1991 Ingersoll 3012 (33rd)
Re: Impregacy's "Moar" 1991 Ingersoll 3012
On an air-cooled MS2 mower engine I screwed a small aluminum block to the head and drilled and tapped it for a Ford coolant temp sensor. It has worked fine.

Got a photo of that setup? I'm curious :-)

Hmm, I guess reality is that you're typically at a fixed temperature pre-starting, and it would be accurate there. From there up, it would lag reality a bit more than a lower-inertia, closer-coupled setup, but you could account for that discrepancy by under-fueling compared to a different measure. And if you always started from cold, it'd track out fine anyway. The more lag that sensor has, the further it is from what the engine really needs, you can't really compensate for it everywhere, but it's likely not enough to care about, either. Cheers.

Sensor response speed has been a non-issue thus far in operation (~3 years). In this instance, "close enough" seems to have been close enough!

Understood. But we're not here to aim for mediocrity; there is another project excelling in that arena. We're here to aim for the stars, and fall short with a full understanding of the problem.

Mediocrity = bad.
This "other project" of which you speak, sounds bad.
Go Fred, go!
