Don't buy the coupon ! I just hate scaming people who don't know how to search. They are free if you just search... here is an expired one, but they are new ones about every month.

harbor freight predator coupon
Sign up for their email, you get monthly adds even better than ads in the store.
Right now they are $149 with 20% coupon, that is $119. I saw them on sale last month for $119. Parking lot sales are where they are usually $99.
VERY easy, unbolt old, bolt in new. The new predator (black) are even easier than the old Greyhound(blue) since they come with all the throttle connections.
Get this new throttle cable
http://www.*************/item/Throttl...-36000750-7252 and just cut the bullet end off, leave the cable long.
Extending the shaft is just a longer bolt - it is a 5/16-24 x 2 1/2 at Lowes, HD. sku # 008236709827, Hillman # 880590. Your clutch will hang off the shaft, but get the bolt tight, it runs fine.
I fought the old Techumseh's for weeks (I had 4 to try to get running), bolted on the Predator, was running in 30 minutes. Now I spend my time having fun !
