I have a MTD 450 Chipper.
B&S Horizontal Engine.
206 cc
8.5 ft. lbs of torque
There is a series of number on the valve cover (it is OHV). They are: 070924  88 85 660 126312 0525 B8
I’m looking for information on routine maintenance. But I’d like to get some more specific information for my records of what
this engine Model is, etc.
I’m looking for
Spark Plug
Air Cleaner
Oil Type, Weigh, and Quantity
etc.

Thanks for any help. The B&S site doesn’t show chippers as a product type any longer.

I'm not seeing that model # listed anywhere... Can you check again?

The first couple of numbers on the valve cover is the engine model #
Next #'s are the TYPE of the engine
 
Re oil, any 10W30 automotive oil is fine or Briggs has their own 30 wt oil.
As for how much, likely less than a half quart, fill using/checking the dip stick
If just a oil fill cap, about 2" from the base of the engine, fill oil up to the top of the threads.

I think it is a Model 126312.
Maybe a XR950?

Ok, here's your engine but you need to narrow down the type(next set of numbers):
