No V-stack.
TNC tach.
6600 RPM on a Pro Zinger 22x10
6800 RPM on a Menz 22x10 Std.
The Menz has superior performance in the air.

Status: online 		i run amsoil 50 to 1 there is also a amsoil thats made that is required to be mixed at 100 to 1. brison uses the hard clyinders. They told me to prop mine for 6500 to 7500 on the ground when i called them over 40 gallons ago. This made me switched out the following 22 x 10 props that i tried:

22 x10 rcs maple 6150-6300
22 x10 futz 6000-6050
22 x10 menz 6400-6500
22 x 10 fortes 6250-6350

Now i only run 21 x 10 or 22 x 8.
the motor did great on those 22 x 10 props but Brison says i could over work the girl

all of the above reading were when i had 2 gallons on the motor

now 40+ gallons
22 x 8 mezn 7000-7250
22 x 8 Mejzlik 7150
22 x 8 Bamula 6930

Status: offline 		OK, so Im not totally out of line getting 6100 or so on a ProZinger 22x10? With a 3W 20x10 I get about 6750.

I think there is about 3 or so gallons on it.

At this point it is pretty weak. Hope it gets better! The Moki 1.8 had about the same pull.

Status: offline 		Brison 3.2 with standard inline muffler

MenzS 21X8 = 7600 rpm AMSOIL 100:1
Zinger Pro 22X8 = 7200 rpm AMSOIL 100:1

These numbers were verified with two different tachs.
I bought this engine used but I had it tuned at Brison and I have personally run about 12 gallons through it.
It is a monster. I prefer the 21X8 MenzS. Makes my DP Extra truly ballistic.

Status: offline 		OK, just got done running it again, I tried playing with the timing but found no RPM increase in the little adjustments I did so I put it back.

I reset the needles to what the book says, then ran it, only get about 6700-6750 on the 20x10 with the first muffler shown in the above links.

So, I tried that other muffler, man is it loud, my ears are ringing, but it picked up a bit of rpm. Right off the bat of starting it it hit 7100 but then slowed to a bit over 6900 and that is the best I can get out of it now.

what do you think? Just need more time?

Bisson pitts muffler with the pinched ends cut off.
I think I gained about 100 rpm from this mod.
The high speed needle is tweaked to max rpm and the low speed needle is as lean as I can go and still maintain a decent transition.
I do not like running rich......it fouls plugs, makes low power, makes carbon deposits, and can cause rings to stick/seize.
Thanks

I am using a 20x8 now, but I know I am underpropping the engine.

Status: offline 		Alright! Thanks John. I've been looking for some rpm numbers on the Bambula 22x8. My Poulan 60 turned mine at 6450rpm and I was wondering how this compared to some of the other motors out there. I know the Bambulas are pretty heavy loads but they sure seem to pull well in the air. This combo should work fine on my Wildhare Edge.
