Brian,


First, I did see your response before writing my previously last one.
In my response I was referring to the person who removed some of my posts and those of others.

This goldfish is going to out-litigate you...

In my discussion with Bob Brassell, he told me that due to their high timing numbers, Jett engines will not be run in a four-cycle state, but rather in an unsteady, misfiring state, when the needle is set to a very rich setting.

Profi engines that you entered here as evidence, are even more wildly timed then Jett engines.
So are they capable, despite their radical timing, of sustaining a real four-cycle mode???

I don't think so and it is probably their way of describing an unsteady misfiring state as well.

I have never run a Jett, or a Profi, so if you want to argue about this issue, take it for a few rounds with Bob Brassell (or maybe with Dub himself).


Also, peaking a brand new tapered-bore engine for a few seconds, to find peak RPM, will not cause it any damage whatsoever.
Heat soak cannot come this fast and, as said, they are nearly ready-to-run and run they do.

Some racing engines are tached by their manufacturer, to check if they are up-to-par (and to fish out the really powerful ones...).
Would they have done it if damage was a risk? I don't think so.

Besides, it is not only my thread that tells you to take this route, but also the instructions of the better engines manufacturers. Oh, and the late George Aldrich...
