nrg/sp50 engine, obviously liquid cooled. Had new piston, rings and gaskets, complete with all transmission internals and cover, and the stator, flywheel, etc. Will post a photo or two. Looking for £70 plus postage, if not collected. Bedford area, willing to deliver at 80p a mile. now sold I didn't build this engine but looking through the inlet, you can see the brand new piston, the two pick up screws are missing, as some of the transmission cover bolts are missing, so are the bolts for the flywheel cover, some of them have snapped off in the case, just need drilling out, quite common to have to do this. I bought this for a complete high end rebuild, then was going to put it in the Runner over winter, neither is going to happen, hence the sale. just add, all the transmission is there, starter motor as well. the price is not open to offers.
