first , just to let you know ... the nitro will NOT mix with 2 cycle oil . ( will separate like water in gas ) and to get pure nitro is NOT easy . ( I run RC boats and cars and use Zenoah , CY and Poulini engines )
When you get your mix right ... you will THEN have throttle control . Untill then , what you are getting , is either a solid shot of nitro , or gas ... you are NOT getting them mixed .
Also , FTR - you do NOT want to "dump" the nitro in , you want it "sprayed" in ( if mixing with the gas flow ) . Read your can of nitro ... bet it says it contains NON PETROLEUM LUBRICANTS . ( which is why it will NOT blend/mix with your gas and why you get a "shot" that you can't control . )
If you want to go with a burst , go with NOS ... ( you can buy small little cartridges like the shape/style used in paintball guns and pellet guns on EBAY listed under WHIP CREAM cartridges . )
THIS will give your little shot/burst of pony power that you CAN control .
here is a link to on of those auctions on EBAY I am referring to :
25 16 GRAM N2O CARTRIDGES WHIP CREAM BESTWHIP - eBay (item 280423305154 end time Apr-12-10 14:17:15 PDT)
BTW - keep flowing nitro into your motor , and soon , you won't have a motor . Again , I run gassers and nitro's and take my word for it .. you CAN toast an engine REAL fast if you don't watch the temps ( caused by/from the nitro ) and using proper lube .
One more thing that might be of some interest to you .... the fellow who tried describing that nitro uses HEAT , rather than spark hit the nail on the head ( thats why nitro engines use GLOW PLUGS and not SPARK plugs ) ... there is a BIG difference there also .
Again , you want a little controllable burst of ponies .... get some N20 instead .
If you have a little bit of ingenuity and think about things I said ... and what those cartridges fit ... you should be able to jimmy-rig a make shift setup to give you , your little shot of ponies that your after .
but , realize .... this CAN and WILL shorten the life of your engine before needing an overhaul ! Too much for too long and you won't have to worry about an overhaul either 8-|
