OS do that

I found you a brand new gen 4 crank,new unused rod to go with it (actually they might have done 1 tank together but thats it)complete with a wrist pin and I have 2 extra rods with wrist pins with less than 1 gallon on each..No discernible play in any of them..I'll throw them in and you can keep them for emergencies.I think your gen4 7-port with a spare crank and rod + 2 xtra rods should keep you going long enough to get your 100 pounds worth

I'll go to the post office in the morning..Do make sure to follow the instructions to heat the engine really hot hot before starting and running in plus fit the run in shim AND unscrew the glow plug a little..those older engines were really really tight to begin with....otherwise it'll just lock up and chew up your starter box wheel..persevere though cause they are nice engines once they are broken in..
