Anybody have any problems with their Savage 5.9 stalling out when letting off and braking???
 
When giving any bit of throttle then braking. I've been reading going to check and make sure carb is not closing during braking.
 
even if it does stall out, make sure your truck is running great at full throttle after letting off the throttle (winding down at a good rate) after that you should adjust your low speed needle to keep it from shutting off after a run... but only do this after youve adjusted your throttle trim
 
It does stall out letting off. I had one of the first savages years ago and it was a piece of cake compared to this thing.

Won't idle that well either have to trim the throttle to get it to start. Really not impressed with this truck tires wobble, one tire is straight and the other is turned slightly. Thought paying that much money for it would be a little better.

If it is stalling while under brake it is probably an improperly adjusted throttle linkage. Plus from the way your describing it is probably not tuned correctly. First off the K5.9 is about the worst engine I have ever owned for air leaks. If I were you I would pull the engine tear it down clean and seal it up good with some copper seal engine sealant. Once you have it sealed up good, the next step I would do is center the trim on your transmitter to zero that's center. Remove your servo horn on the throttle servo and go full throttle then brake. Re install the servo horn back onto the servo. Put the rig back together and make sure slide on your carb it going closed and open all the way. Watch the slide on the carb if it moves when applying the brake then the linkage still needs adjustment or the trim may need some minor adjustment. If it is stalling at brake it is an improper set linkage. When I got my XL the previous owner had so many issues new out of the box he didn't even finish break in before he decided to get rid of it. Once you get the problems worked out there a good rig. Like I said the K5.9's leak more than any other engine I have ever owned.
 
yeah i just finished the break in i'm on 7th tank of fuel trying to tune it.The throttle linkage with the spring how should i adjust it? I took the filter tube off and looked at the slide in the carb and it does move when braking. Any advice on the wheel alignment and wobble.

I had the same problem with mine even after it was sealed. I tried to adjust the carb to no avail so I put the high speed at 1 and a half turns past the groove and it helped. Then I went ahead and tossed the R5 glow plug for a McCoy 59 and it runs way better now. I personally feel that the R5 cold glow plug is for higher nitro content fuel and the McCoy plug is hot plug made for lower content fuel.
 
A brand new motor should be good to go. How ever I can bet its the links and trim.
Read your manual and it will tell you to go over all those steps befor attempting to start.
Also I highly recommend you put a throttle return spring on the carb. This will help it keep it closed and will allow you to make a better judgment on your link setup.
 
Thanks for the input u will try all of the above and let u know the outcome.
 
Readjusted the throttle linkage and man what a difference no carb movement on when braking haven't ran it yet but can see a big improvement. Adjusted the linkage on the front end and lined the wheels up. Set the carb back to factory now all that's left to do is pick up a new glow plug and try it out fingers crossed!
 
Yep, I bought a new XL Savage last weekend, had the same problems but it was a easy fix. I broke it in exactly as recommended but the engine had a flat spot in it, and would stall out when I hit the brakes. I took the air cleaner off and watched the carb slide when giving it throttle then when braking. When I applied the brake the slide would completely close and choke out the motor, I adjusted my throttle screw so it would not close all the way when the brake was applied but would still idle correctly. This cured the problem with it dying, next I had to play with both low and high speed jets till I got rid of the hesitation and the dead spot. The truck is now awesome!! No hesitation what so ever and extremely responsive. There is nothing wrong with the 5.9 motor in my opinion, just a little touchy to get it tuned right from the factory.

Yep--this along with flooded engines are the two most common problems I get asked about. I often wonder if the guys who complain about the 5.9 just don't know how to tune...and I mean properly race tune. I cannot believe how poorly tuned some guy's engines are (and it's normally the ones who are bowing up about their engines and what monsters they are who are the worst at it). Ha ha. I'm learning every day how to improve as I am a newbie, then see some of these so-called guru's vehicles. Damn. It's amazing. But they have it all figure dout

All too often people blame the vehicles and not their unwillingness to realize there is more to learn then what they already know. But then again that is what separates those who are successful vs those who are not. .

a Big issue here is the Savage has a very poor functioning throttle linkage, and because of that people have all sorts of tuning issues...... The throttle linkage functioning correctly is critical to being able to tune the engine correctly... Honestly makes me wonder if the guys from HPI actually run these vehicles, and if they do at what skill level, are they a bunch of newbies who don't know any better ? ...Very poorly engineered design that should have been corrected a decade ago....responsible for thousands and thousands of people having nothing but tuning headaches......

Anyways OFNA throttle mod..........this will solve the issue....

Couldn't agree more man. I've seen alot of new rigs that are just very poorly designed. I really wish companies would got off the brushless high horse and make it easier for people to learn nitro. After all nitro was dominating the rc world and really got everyone in the hobby.
I sure hope hpi gets it together on the release of 1/8 scale gas..


for a newbie to start up a kit and have it fail because a company dont have quality control really puts out a dreamers flame.
And to anyone reading this and thinking "well they should have done this and this" stop it! If your paying $600 for a kit you have the rights to expect 100%

i agree man, $600 for a truck thats smaller than your boys wagon is to be expected of performance amongst other things. Tuning does help things, and so does adjusting. the thing is though, sometimes tuning wont help, and sometimes things come broken. tuning is tuning, and something being broken is poopy product if its delivered that way.... one thing you gotta think, and its said, people who make the vehicles dont give a damn, theyre just there to make money.
 
Some valid points all-around. I have been fortunate in that I've not had a vehicle some with problems that I can recall. They have design flaws, which is different then a defective item.

I personally don't mind the Savage linkage. I've not had any problems with it. When I get the new engine I will incorporate a different link setup as I agree its a very important (and often overlooked) attribute). You can only do so much with the Savage one...but it's not never me caused any issues. I see other newbies struggle more with traditional two-lever ones---but agree they are better.

The biggest "danger" with the Savage linkage IMO is actually the TF-40 tx. The throttle trim is VERY easy to move by accident...and I know of a lot of people who have started at or close to WOT.
 
honestly I've not messed with my throttle linkage too much, i think I'm going to go out this weekend and tinker with everything i havent. I've got my tuning down on spot, now i wanna mess with my linkage and such, maybe adjust my suspension more extensively and adjust camber and toe. lol thanks for putting this thought in me head
 
I have never had to mess with my throttle linkage on either my Savage 25 or my Savage XL, all problems have been in the carb adjustment.
