Hi, I wonder if this is a really silly question? But I really have this question in my mind.

Once we are done breaking in th engine, is it fine to give full throttles right away or should we hold back? Also should the engine be shut off and let it cool completely and start running the engine normally with full throttles after a few hours or mabe the next day?

Good question. Answers to this may vary. IMO, I would run the car the way everyone else wants to run it. A typical engine would last about 20G or so, if you were careful and took good care of the engine, you could easilly outlast 20G. But then again, by the 20th tank, you might as well get a new one because of ware and tear......

So to enjoy it the most, drive it the way you want it. My Inferno appears to be on crack right now because I ran it 100% right after break in, and no, I wasnt letting off the throttle either. The performance on the engine got better, fast response, good high rpm, good top speeds.....

It also becomes easier to tune after you drive it like you stole it, the needle settings will become more tolerant. Once you thought it cant run with this setting, you will find that it now does.

i would use something other than blue thunder, fuels with high/higher amounts of castor oil are a bit more forgiving at tuning, vapor lock can be caused by an engine that is running lean, inadeqaute airflow, or both, you can use blue thunder if you want, i would get some castor oil and add it to the fuel, not a big deal, and they run much cooler, when i made my own fuel for the first time, i used 10% straight castor oil and my engine had to be leaned over a full turn to run right, then it was flying and running cool

Apollo,

What fuels are high in castor, I use trinity monster HP 20%. Can you do a post on how to make your own fuel? Oh and excellent thread it was really insightful. Don't worry if people didn't give you grief about your how to guide it wouldn't be good guide.

Fix a car for someone and they will be back in an hour. Teach them how to fix it they will be back in an hour with a new problem.

vladconnery, I don't know how much experience you have with nitro rc, but I really wouldn't recommend trying to make your own fuel. The resources are out there but they are difficult to track down. You would have to buy the ingredients in bulk its a real pain in the neck. Before you know it your gonna be wishing you would of just paid the 30 bucks for the gallon instead paying around $1000 for the 42 gallon barrel of nitro sitting in your garage.

Thanks,

Thats good to know I'll move on from trying to make it. Which brands are high in castor content I also notice people add castor to there mix. Is this a good idea considering fuel may already have lets say 14% oil. If you add more you are raising the oil content are you not? I started out using traxxas 20% it was the worse switched to trinity MH 20% noticed a difference for sure. However trinity nor most of the fuels I look at say what type of oil it contains. Looking for a fuel with more castor content atleast half and half would be nice. If you know a site that breakdowns the different nitro brands by quality and content could you link it for me?

Troubleshooting help please.

My MGT 3.0 has been broken in. My needle setting according to the manual is 2 and half turns. I run it 1/4th turn richer. But sometimes the enigne flames out. When I have run it and the engine is warmed up it runs fine. I must mention it that i start the engine with 1/8 turn richer when starting from cold and let it warm up and then get back to my original settin i.e 2 and 1/2 turn+ 1/4th turn out.

If i am running pretty rich why is the engine flaming out. The egine just cuts out when i come to a standstill. Everything is fine if the truck is in motion. Also after the engine cuts, I have observed that the carburettor is really hot and as soon as I prime the fuel line, the fuel just evaporates with the heat. I then have to let it cool down before restarting it. I am just using 10% nitro with oure raw castor oil as lubricant.

Shall I reduce the needle setting or increase it? the engine has gone through 15 tanks of fuel.

Could be that fact that it is a lean mixture, what is your ambiant temp? do you know the temp on the head sinks? Check your glow plug to see if any black stufff develops.

If all the above is correct. Then i must say that your idle rpm may be too low, or your low end is too rich. And that your high end may be too lean as well.

With a warm weather, normally you wont need more fuel because oxygen density is lower in warm air. So if it is still shutting down, there could be a few possible causes.

Is your high end rich enough? If its too lean, the engine will shut off when you accelerate from idle. The problem with wheel spining could be either a loose clutch spring or your idle rpm is too high. Have your Kyosho Inferno sit off the ground with wheel free spining. Then adjust the idle screw counterclockwise untill engine shuts off. Sop turning when engines shuts off, and turn back clockwise half as much as you did with this adjustment. You may have to lean the Low speed needle as well since you are using low idle rpms. This will make your low end rich, so lean it a little like 1/16 or 1/th of a turn clockwise.

FOr a needle setting diag. See below.

are you running too hot? Try either leaning or richining the HSN and see how it does. one of them will work. Do a high speed run, and then brake and idle, listen to how the engine sounds. You will need more tanks before the engine is properly optimized. I've had the same problem with my GXR28. Just give it some time.
