Re: Tecumseh small engine RPM settings where can you find them?
On that 22" cut mower it is 3300 (3298) RPM that produces the 19,000 ft/min blade tip speed.
This is per The United States of America Standards Institute, sponsored by the Outdoor Power Equipment Institute has recently revised the maximum blade tip speed of 21,000 Ft./Min. downward to 19,000 Ft./Min. SB 107 Revised 6/95.
The engine is a LEV115-360026D per Sears to Tecumseh cross reference guide.
