Hey, I met a fella last week who said his brother owned an 066 for bucking. Saw hasn't been used for years so he brought it to the shop to see what it needed. It needs a fuel tank( current one is cracked) and a piston( there is play with the piston). Mechanic says if I supply him witha a piston and fuel tank he can get it running for 80-90$. what is it worth now?
