I couldn't wait until morning... :)

Ended-up paying $35.

It's an Allis-Chalmers Tracker 7 (like raptor0192's).

1970 Briggs Flatty 170402 (I assume a 7Hp since it's a Tracker-7)





The machine has some surface rust...no rot that I can see.




The transmissions on these things are massive! It's literally the size of the transfer case on my silverado.

It has a 26" pie-hole:




beefy auger gearcase:


Even the belt cover is steel:



when buying an old-school briggs, the fuel tanks are always a concern...and this machine is no exception. Not sure if this beyond saving...

I've been wanting to tear into an old Briggs for a long time...



...and not soon after:


There was a pile of seed husks in the carb intake...


...which probably explains the burnt seeds on the piston :laugh:

So the short list on this thing are:
  • reseat valves & adjust clearance
  • clean / rebuild carb
  • clean / seal fuel tank with new fuel line/filter
  • new head gasket
  • tighten-up the recoil
The only thing screwed-up on the tractor itself...is that there are 2 busted bolts that secure the transmission to the chassis. I'm grateful that the tire isn't seized to the shaft...extract those bolts and she'll be good to go.



I'll do a full restore on this thing...eventually.

Looks to be in pretty darn good shape. It'll be fun to follow your work on Allis.

The owner's manual didn't come up on Simplicity's site and nothing on Jack's Small Engine, using 2029956. Might have to call them to find the manuals for that one.

This machine was probably made by Simplicity.

Scot
A did a little research yesterday before committing to the purchase.

This machine shows-up under Allis-Chalmers (Tracker), Simplicity (SnowAway) & Homelite (S8).

Home wrecker!.....
ha...that guy had plenty of other flywheel shrouds & air intakes for the vermin to find refuge!

Seller was our kind of guy... A dodge reliant-K was the newest internal combustion engine that I could see on his sprawling property!

Probably the last update on "Big Bird" for awhile...

...I was hoping to get this Sherman-tank blowing by next weekend however the busted bolts that hold the tranny to the chassis will require me to pull & split the transmission in order to extract the broken bolts (red arrows):


I'm eager to see what horrors lie in the carb bowl however the emulsion-tube isn't going anywhere anytime soon...and on these updraft carbs, you can't split the carb until the tube is unscrewed from the carb body.

^^^ ok...I lied :wavetowel2:

screw extractors have been as useless to me as teats on a bull...until now! I worked the emulsion tube out until the last stretch when it bound-up.

^^^ there's a new tube & jets in the rebuild kit already on order.

...and the contents of the float bowl didn't disappoint!

Great deal CC. Here is a link to the engine service manual for that engine. Good luck with the restoration.
