[QUOTE="sawfun9, post: 3322049, member: 60539"] I doubt the saw would run on 100% nitro. I tried 85% in a Briggs&Stratton and it wouldn't even pop when added to gas and the engine at full rpm. Nitro needs compression to light, not as much a diesel but it behaves in a similar manner. A naturally aspirated engine needs about 12:1 or so. If you supercharge it then 7.6:1 will work. Oh and you'll need to have a lot of spark at 50-70 degrees advance and about four times the amount of fuel. If you do this, cover it in Kevlar like a top fuel engine and stand back, way back. One more thing, Leave the muffler OFF, It will literally hand grenade on you. Have fun with the fireworks show. [/QUOTE]
