Super Custom 80FS Setup Questions
 

I have acquired a new SC 80 FS with no directions as to setup so I'm Lost. The spiget on the bottom of engine is this to inject fuel or oil? How do I tune this engine as this is the first 4 stroker I have seen. any help would be a great help Thanks

The fitting on the bottom is a crankcase vent. You don't NEED to do anything with it, but it will spit out a tiny amount of black oily gunk, so you may want to attach a piece of tubing and vent it out of the cowl (Assuming the engine is cowled)

Tune it just as you would a 2-stroke. For that matter, do everything the same as a 2-stroke, except run 10 to 15% nitro and only use a 4-stroke glow plug.
