thanks for that Ken. I didn't know that but makes good sense and will keep it stored in the jumble at the back of my brain.
I guess that also applies to any changes made to needles and pinses

Apologies but it just sort of rolled off the top of my keyboard LOL.
I meant needles and pilot jetses?

Now I'm getting worried

That's actually why we have the elevation column in the Dyno Table otherwise it can confuse why people have this jet or that.
Actually, as I do the dyno table if anyone does want to let me know what their elevation is, I'll ammend the table. Just makes it more of an accurate tool that's all.
