tuning

This is probably a gone over topic but I'm a noob at this and have video to back up my issues. any ways, what basically happens is it wil not idle or at (seems to be) top of first gear it will stall out. Greatest part is that I went through water and snow a few too many times and screwed my...

Hi all, I recently fitted a GO 21 GX 5R to my Losi 8ight Truggy. I spent most of the last race meet trying to tune out a lean bog on acceleration - I had a bugger of a time tuning out the lean bog . . . in fact, the engine won, I never really got it running right all race meet - VERY...

I have a traxxas nitro sport and I'm having problems tuning it. It is pretty new, not even a gallon of fuel ran through it. I adjusted the hsn and it was running great! I was driving it around and about 2-3 min later, it just doesn't want to move in really any throttle position then it will just...

I spent most of my Sunday tuning my savage, I got it accelerating fairly sharp ish but still no wheelie action!! And when I removed my air filter to clean later I noticed that the throttle action is restricted By the petrol tank!! Is this my problem why I can't seem to get it to wheelie and how...

I have been having a strange problem with my 3.3 lately and I can't figure it out. The engine will not start and run on the same tune. What I mean is that I have to lean it way out to start it and then once it is fired up I have to richen it up almost 3 full turns to get it running properly. I...

Last time I ran my x I cleaned and oiled the filter with Uni brand oil. So today I go to try some new Torco fuel. Well I had to re adjust the high and low but she just wasn't hitting the high speed. Could it be the air filter oil I used or the fuel?

Well before the colder weather my Revo was running perfect. However, now that the temp has dropped 30 degrees I'm having a little issue. I know that when the temp drops you should richen the HSN because of the denser air. My Revo was running a little warm (280-300) so I richened the HSN to get...

got a used savage XL and while tuning it i mistakenly adjusted the mid range screw. I had originally turned it flush with carb body and then adjusted from their. The top end is running perfect shifting properly and not over heating. The only issue i have is it has a slight bog on takeoff from a...

A buddy of mine gave me his Ofna Picca .26 to put into my T-Maxx. Got everything to fit with no problems...down to the EZstart. Everything works...but the carb on it is so out of tune that its crazy. Looked up the factory settings...and they just don't seem right. 10 to 11 turns out on the...

OK.. Trying to tune my Savage X 4.6. Running quite cool, so gradually leaning the engine in 1/16th turns to try & increase. As I start getting closer to the correct temperature, I have noticed a couple of things.. 1. It sometimes stalls as I accelerate from idle. 2. It's bogging down at lower...

I've had this trophy 3.5 buggy by HPI for a couple weeks now. I broke it in using odonnells 20% race blend with 8% oil. Its ran great for breakin and several tanks after. Then i switched to byrons 33% with 16% oil and it ran one tank fine and picked up a bad low end bog. I figured it was the oil...

I've got an Acme Condor with .15 engine. I'm trying to tune & adjust the engine/idle speed (only has one adjustment needle & idle screw). I think the throttle linkage needs adjusting, but I can only seem to adjust it to idle correctly or open full throttle. It doesn't seem to have enough...

Hi guys just need advice on tuning with the hpi temp gun and what is the ideal temp to go for cheers

I bought a Revo 3.3 (5309) a month ago today and have been having a lot of fun and frustration with it. This is my first nitro truck after having wanted one for many years and trying to tune it has been really frustrating. I used the flow chart from this site to getting the truck drivable: no...

the manual with my nitro car says 3-4 tanks of fuel is recommened for breaking in at half throttle whats everyones opionion on that ? and should i start tuning the car ? it rolls when it idles , do i turn the idle screw when the car is running or when its off?

I currently have a jato big block swap with an os 21xz-r speed on it with all the supporting mods done. I am having a little trouble getting the tune dial in correctly, i set my hsn at 3 turns out from fully closed and lsn flush with slide body. it runs decent but occasionally after a wide open...

Hi guys. I put a picco .26 red dot maxx in my t-maxx and have some problems tuning it. Got it broke in, no problem. After it warms up the idle does nuts, up and down (very fast). I read all the picco tuning forums and call picco. They said my problem was my pipe. (I'm running a 053 pipe with a...

I have a brand new 454 in a Savage 25, with an aluminum HPI pipe, and I'm a bit unsure of my settings. I've got the HSN at 4.75 turns out from closed, and I had the LSN out about 2.75 turns from closed, and outed it a bit more, though I'm not sure of the results. The engine seems to load up a...

After I get my Picco .26 good and hot, it starts to die right after a WOT pass. Basically WOT, off the throttle, it dies. No rev up, no sputtering. I've used the flow chart but I'm not getting anywhere. Any advice and it only happens when it's at 220-240 degrees.
