Hi I have a nitro truck that i would like to get expert help on tuning. You may have not heard of this brand, but its called a Sportwerks Reaction, it's a .18 engine 2wd and 20% fuel and electric start. what i need help on is i can't seem to tune my car the way its supposed to run. its running temp is 400 degrees.
Here's how it all started....
I got the truck off of ebay, next bought some fuel, glowplug, and battery for the car. cranked it up on a stand, cranked up fine but the idle was set way to fast so i adjusted it (NOTE I NEVER ADJUSTED THE HIGH SPEED NEEDLE). Next i took it off the jack and took it to a parking lot and got the feel of my first car. i ran the whole bottle of Blue Thunder 20% fuel which is wat is recommended for it and went out to my local hobby store and bought a brand i have never heard of. the brand was called Brister's Brew 20%. Its some hobby store on dallas Tx that makes there own fuel. So i poured the new gas into the car cranked it noticong that it took alittle bit longer to crank up i put my battery on the charger, because sometimes when the battery is low the starter and glow plug dont work so good. 30 minuates later cranked it up started on the first 5 seconds of starting it ran it for alittle bit and about half tank WITHOUT ADJUSTING THE HIGH SPEED NEDDLE it stalled and died. i took it to the temp gage and saw that the temp was around 400 degrees. i thought that i blew up my engine because it was smokin hot to the touch even the frmae was hot to the touch. so i let it cool down for a LONG time cranked it up, it was fine no problem then while driving at 1/2 throttle it just died. I didnt gunt it or do anything to make it do that. I mena i drive pretty hard but that should not be happening.. So now i'm really mad at the car and start messing with the high speed neddle.. [the carb does not have low speed neddle only high speed and idle]. I thought TO LEAN so i richened it and ran it again still same ending, but the temp was around 350 so i richened it alot! hoping this time would be the time i filled up the tank full started it and now its taking forever to start the thing. finnally it started and it did it agin and now the temp was back at 400!!!! whats wrong with this car?
Now i have seen on this site that an engine can overheat from leaning it out to much and even to rich. what does that mean? it seems like either way i do anything on adjustments nothing seems to be working.
Now here is all my questions that i would liek answered.
1. is it to lean or is it to rich?
2. how is my new fuel making my car's performance SUCK?
3. should i buy a new angine and carb so i can put pull start?
4. what am i doing wrong?
I'm seriously concidering tkaing this thing to a pro and let them worry about it but i want to gain my own experience.
Anything yall can do to help i'm sure will help i just need some basic tuning guides since i'm a beginner..
Thanks, Nathan
