I think this might me too much motor for that 74" Corsair....

PSHHHHYAA! Who am I kidding, think I'll just pack a parachute into the fuse in the wing saddle area, that way when it pulls the wings off the chute might save the motor...

This is why I get involved whenever the topic of a Webra Bully is brought up. They are amazing engines and when set up proprerly they run fantastic. I have heard unsupported reports of the Webra Bully being ran at 14K+ RPM on methanol with tuned exhaust! That is smokin' hot for a 35cc engine.

I have all the "goods" to give it a try but have not tried it yet. My interests are the gas conversion.

Here we go again! Just when you thought it was safe to go back into your shop...
Just got this as part of a trade (sort of the thing thrown in to "sweeten the deal" ). It is believed to be a Sachs 3.2 with a Bennett mount and B&B muffler. I can say that it weighs a ton, but for a warbird like the CMP 80" Zero, that would be great. Anyone recognize this thing, or should I go fishing with a new post?

I take it you are not a sachs fan? I know little about them myself. I knew one guy who had a sachs 3.2 on a corsair and it pulled the heck out of it, but I didnt pay attention to what the engine looked like.

They are very powerful engines but they were not balanced very well and would shake the begeesus out of a good airframe.

Is that in the recip assy. or is it caused by the old school ignition? If it is an issue with the flywheel, conversion to e.i. would be good on several fronts.

Hey speedy, just as with the bully, I was not looking for a motor. I have wanted a DLE for a while and planned on getting one at some point, then came the rear exhaust one, but its kind of pricey (right now anyway, and the twin 60, mmmmmmmmmmm, good for round cowl warbirds.....). These old things just keep finding their way to me, and I have to, for some reason, get them going. Just like with the softail, the notchback, the 78 z28.... Im not really out anything on this one, if its not worth fixing anyway. But if it runs, someone somewhere might want it, nostalgia maybe?

Thanks TKG, is that a good or bad thing? ( I know as much about quadra's as I do Sachs)

My cousin had a Quadra engine that was not too smooth running. He sent it to Dario B. and Dario balanced the engine and we ran it too see what the ouctcome would be. Well it was really a lot smoother running after that. Dario caled it "OVER-BALANCING" . I Contacted Dario a few years ago, but he would not give any details what he did....end of that data.

I found Dario on a old engine website called Smokestak. He builds small model engines and they are really made nice. Best Regards Capt,n

Hi Speedy
I would appreciate some advice on my Bully engine. The engine is fitted with a HDA carb and has never been run nor had any  gas thru it. The ignition is in a black box "Webra Thysistor- Zundung" Do you think the carb will still function after 25 years in storage? You also mention that the ignition on these units was problematic? 
Kind regards.

CAPT'N....if you need a WT-540 carb just let me know.

I'm in a real good mood tonight. I maidened my Goldwing 50cc Ultimate bipe today and everything was perfect.

Yesterday I took my Dad 70 miles south to Celina,Ohio for a Fly-In with temps at 100+. The heat was intense but the time spent with my Dad was priceless.

It was his 81st birthday.

speedy do you still have a wt540 carb? I bought a bully with delorto carb nitro conversion. Runs ok but wouldn't mind the upgrade. Email [email protected] thanks in advance
