I just bought a 1974 RUPP Nitro II 440, from a buddies step-brother. And it ran like 2 yrs ago until he blew one piston. He re-bought the blown piston and put it in. I need help to find its Torque Specs. I can't find them. Please help!! Also where can I find a throttle cable for it, the fuel ratio, and a really cheap windshield! I hope I get lots of ideas of whats wrong with it, and some tips in buying those items. Thank You In Advance.

Thats one just like it but isn't it!!

Check out... Dennis Kirk, they carry a lot of stuff for Vintage sleds.

also Al's sleds (something like that)

oil mix: I would start at about 32 to 1 .... later maybe 40 to 1

torque for heads?????????? most are around 18# just a guess.
