Well today was the day I took what I learned from this thread and broke in the new buggy. Its been 4 years since mt last nitro and boy it was like starting all over. I have to run the rest of the gallon out, but already noticed how much easier(not to mention more fun then sitting there waiting for tank after tank to idle out) this was. Now I am off to read the tuning bible. Thanks a million for this thread.: smile:

Please somebody help. I just bought a Kyosho Inferni ST US, it has a good idle speed but if I give it more throttle it breaks down and I don´t know what to do. Thank You very much

Hard to tell what’s wrong.
My first thought was it runs too rich. Try keeping the glow driver on the plug, after you start the engine. That would help the engine to keep running, when you open the throttle.

I understand the concept. I am up to the last couple of tanks, before race tuning. Its been getting harder to start. Temps been from 190-207. I have a roto start. So now it will spin for a few and it gets stuck in the pinch. And I have to take a screw driver to get it past. So I do it again same outcome. I am truly lost now. I thought this was going to get easier. It also had a great smoke trail when it was running. Please any help would be great.

were you heating the engine before starting it each time? this should make it heaps easier to start.

jettaturbogls

Yes, I was. That's what I don't understand.

maybe too rich flooding engine?

I'll try leaning it a little bit. But as of now I cannot give it close to half throttle. It will bog out. Then it will take a few quick raps to get it back. 1/4 throttle is fine, anything else it will bog.

yeah i would say to lean a bit and see how it goes. the factory settings would be very rich

There is a cool tuning chart floating around here somewhere. It would really help you.

Ok so I finally got it popped off, i leaned it and it got worse. So I went the other way. That is the best it has ever run. Tons of smoke, but it ran hot. About 240. So does that mean I need a colder plug? But wow it was fast, for not a race tune.

Hi.

If you run the plug from the kit, and you use some nitro in your fuel, that should not be a problem.
You don't know if your engine is set too lean. Try turn the HSN ½ turn out, and run your car. My guess is it will run rather rich now (4-stroke). If it still screams at wide open throttle (WOT), you should turn the HSN another ½ turn out. The 4-stroke mode is a perfect startpoint, because you will not be able to adjust an engine, if its too hot (lean).

Take a look at the videos from the Tuning Bible thread:

Just began my break in today. I just finished run number 5 of my 3 minute runs. Letting it cool and then I got about 4 more left.

Finished my break in this morning. I began to tune it and my RC8 is hauling some serious Arse! I think I have the HS needle set in the sweet spot and it is running great. Thanks for a great thread guys.

Ok here's a question. Do I get the engine to temp and then run it at temperature for the suggested time intervals? Gonna break in a new Dynamite Platinum 12 in my FT GT2 soon. Wanna be sure I get it right.
