Max II 22hp predator test run

[teddotson]

Just a short test run with the upper off.

6 weeks of mostly my son and his friends labor, 6 new tires, 1 new wheel, new chains, bearings, and oh yeah a new motor. I bought this new 20 years ago and it still brings a smile to my face.

Sounds pretty quiet. Stock Predator exhaust?

[Mike]

Seems to move quite nicely!

[teddotson]

Yep, stock exhaust for now, thanks for the edit Mike. It accelerates hard now, I always felt the 14hp left a lot to be desired, but this seems nice. Trail riding this weekend. Going to try to make Busco one time this year, a new grandchild is probably going to interfere with April though.

Nice! Keep us updated. I need to find something to repower mine soon.

[Limbsmith]

Awesome! That is my goal for my Max IV. I will be buggin you when I get going.

Feel free, it's a pretty easy changeover though from a vanguard. Slot out the engine mounts to get the right clutch alignment and mount it up. Exhaust was fabbed up with a 1.5 inch u-bend and then a 90 to go out the side. The governor was a distinct problem and was removed. Fab up a good linkage direct to the carb for good power. It scratchs off from a dead start on dry ground now. I am going to rejet the carb, it's very lean. Makes it cold natured to start. 2 extra sets of jets come with it to drill and play with. Also in wiring it in I removed the needle from the fuel shutoff solenoid as that is a common failure item and really not needed and cut out the low oil level sensor because I know how to check my oil and don't want it cutting out on hills. If anybody needs any pics or wiring diagram help just shout, happy to help.

I also did the same motor swap. How did you remove the governor? Some pictures would be nice.

[teddotson]

Pics will have to wait until next weekend, but I will certainly post some. Also the predator wiring diagram.

[teddotson]

For bypassing the governor we cut the cable attachment point off its mount, flattened it and bolted it to the intake on the other side of the motor. The Zbend in this kit will attach it to the carburetor or you can find this kind of thing at the local lawn mower shop. Just removed the governor arm, the internals will come out next time the motors pulled. I will post a pic next weekend when I get home.

I deleted the fuel solenoid and oil level wiring. You have to remove the carb and pull the solenoid to remove the needle valve on it and then reinstall the solenoid. After that its just three wires charge start and kill. I have this in a big PDF too large to post, anyone that wants it just PM me your email.

For a governor delete I removed the governor arm off the shaft and sawed the throttle attachment bracket off.

Then I hammered it flat and ground on it a little, then bolted it to the intake manifold on the right side of the engine to reverse the pull direction.
