I just went and bought a Allis B10 its a 66 or 7. Runs good, just rebuilt card but still having an issue with fuel overflowing the bottom intake. I did put new float in, but believe issue might be in plunger type thing on bottom of float and the clip. has anyone had any issues like that? Also what type of oil in rearend? and the final newbie questin is why do i have an extra wire hangingdown by my mag. whats it go to? theres two on magnito already which looks right this lines a third(pic 1) where does it go. comes from the engine. Anyhelp greatly appreciated.

I don't have any pics handy, but the tab on the float, that presses on the needle (plunger looking thing), need to be bent so that it opens a bit more. With the upper part of the carb upside down, that float should stand level, or slightly above level. That enables it to close and shut the fuel off when the bowl fills.

I simply get parts from buying tractors locally, or chatting and trading with all my online tractor buddies. I'll grab stuff off ebay too, but that's quickly becoming an expensive way to go.

The Wonderboy 700 has the original 6-12 Schenuit diamond lug tires on it. She's my baby...might be my favorite of the whole lot.

Yeah, they are great machines. Easy to work on, and a good following of folks who are willing to help. They are pretty bullet proof, with a few weak points being the BGB, axle tube, and steering components (steering gear, ball joints, and center pivot on the front axle)

I like the way they handle and the old Briggs' are a great, long lasting engine. It's amazing how these will do so much more than a modern lawn or garden tractor. My passion for them started with the dream of owning some of the rarer attachments...there are so, so many, both common and rare. The attachments are built like the tractors and are easy to use and work well. At some point I will try to document how many I have. It's a lot. Many 'dream come true' moments. =]

I don't know of a modern equivalent to the Schenuit. Best odds are to find an old 6-12 set of rims with the tires in OK shape and tube them. I don't believe the B-10 ever had 6-12's, but some early one's were said to wear 8", with their later cousins having 8.5" Goodyears. I'm not sure what 6-12's the B-1 wore...Goodyear Terra's as well?

We need to see a bit more of your machine!

The gears can become a bit loose, then they wear. If you have things cleaned and snugged, that will go a long way.

The ammeter...I've rarely noticed them working, and couldn't even tell you if mine do.

The parking brake should work about as well as your braking when you use the pedal. There should be an elbow piece of round stock that threads into a bracket on the brake rod, through the frame on the RH side.
With the brake depressed, the 90 elbow turns clockwise until tight. It should hold the brake rod in place, keep the brake band tight.

Warm the engine. Shut her dow, and turn the fuel screws in until tight (not too tight!), then back them out about a turn and a half. Fire her up and at an idle turn the idle mixture screw (upper one) in until it starts to lean and run rough. Back it out past where it started, until it agains runs rough. The half way point between the two is where it needs to be (should idle nicely at a very low rpm).

Increase your rpm until until high (if it will without running rough) and follow the same proceedure. You should find a nice full throttle sweet spot.

Here's the governor spring settings:

hard to tell from the pic. The original light wires ran up the RH side of the tractor, up top. (I've never seen anyone hassled around here for long as we can decipher what your'e sayin!) =]
I far as I know, only the plu wire and wire for the points comes from under the shroud...the kill wire comes from the switch and goes to the points, as shown in your pic. Not sure what to tell you about the mystery wire =]
The wire goes from the points to the key switch. When the key is turned off, it grounds out the points and kills your spark.
