O.S 1.08 FSR ( BX-1 ) with correct O.S. #855 muffler. The muffler is new in the original box.
Engine and muffler...............$185.00 plus $12 for shipping lower 48 USA.
This engine has been run on the bench for run-in but never in the air. Ran on Wildcat 15% Premium Extra with 18% lube ( castor/synthetic ) mix. 2 five minute runs at a rich setting and full cool in between runs. 2 five minute runs alternating between rich and correct needle settings and full cool in between runs. 1 ten minute run on Wildcat Premium alternating between 4 and 2 cycle settings achieving no sag at W.O.T.. Ran engine out of fuel, oiled and stored in controlled environment.
These engines are very underrated for stump pulling power and are fitted with the famous O.S. 7D carb for excellent throttle and transition.
I also have the correct MACS #1290 muffled tuned pipe and the correct 3 bolt MACS #2940 standard header for extra if interested.
Both header and pipe are absolutely new and unused.
If you want the pipe and header the pipe is a $130.00 item new and the header is another $43.00
Depending on whether you want the stock muffler or the header and pipe I'm sure we can work something out.
