The Toro string trimmer engines are getting hard to find, and you need 6 of them, good luck.
I paid $35.00 when they were easy to come by.

The Toro 2 barrel I would say is a higher performance engine than the Homelite.
But people have been working over the Homie so long it is probally faster.

If you want a cheap used engine with lots of potential I say go Echo.
