On ebay, the round edge 4 stroke tach is $5.25 USD. I've ordered one and I'll see what it reads on a 2 stroke saw. I'm guessing idle will be 5500 RPM (normal is 2750) because of spark every revolution. But IIRC, a Briggs, Kohler, Tecumseh single cyl will spark on exhaust stroke, too, so it may read double on a lawn tractor.

I have a 2 stroke one on a industrial 4 stroke kohler engine & it reads correctly.

Well, I ordered the $5.25 USD tach-hour meter....and it's ONLY an hour meter. Tough to check RPMs. LOL

Looks like a clear case, refund or send another unit to You.

I haven't had dealings on Ebay, but from what I have seen the sellers will rather correct a wrong doing then risk a bad rating.
Try contacting the seller and point out the matter/error.

Good luck! :)
 
Yeah, I've contacted seller and said "item not as described" And most sellers will make it right because they don't want a negative rating.
 
Email form seller. They'll make it right. They should avoid those ignores. LOL.
