Default Carb slide sticking

I have been trying to figure out why my car was running so bad (if at all). When I checked the linkage it wasn't even moving the slide AT ALL. I sprayed WD on both sides of the slide and it seemed to help a little but now it is back to sticking shut again. Should I pull the carb apart?

Thanks

been there done that....I'm assuming your talking about the 2.5 (peice of crap). It wouldn't fully close until I hit the brake and then it would "click" back to neutral. Keep putting WD-40 on it. Thats what solved that particular problem. But I've had so many problems with this engine (Keeps stalling), I'm ditching it for the Sirio .18.

This is the Savage motor. It is really hard to tune now that this is happening.
Maybe if I pull it apart....

I am bummed that people are having problems with the 2.5 since I just got a new T maxx 2.5. Now I am wondering if I should sell the motor on EBay and get the Sirro instead.

Thanks PO Jack. Even soaked (on both sides) with the WD I can still feel the stiction. Do you think it is a dirt issue?

I've talked to many people regarding the 2.5 and they all say that it's hit and miss. SOME are great, but others are hard as hell to keep from stalling. I personally think traxxas had a bad batch of them produced and unfortunately, I think mine was included in that batch.

That really sucks. Are they going to give you a "trade in"?

Try working the oil in...with the engine turned off, keep on hitting the throttle then the brake. If it sticks, manually place the throttle arm where it should be....continue doing this for a while. I did this for about 15 minutes and it eventually went away on mine.

Honestly, I don't know if they will or not, but I am pretty sure I'm going to go with the Sirio set up. I've tried everything for the past 4 days trying to get this thing to run right, and it still stalls non stop. Tomorrow is the last straw...If I can't get it running properly tomorrow, I'm buying the Sirio set up.

Didn't work. It feels like the slide gets bigger at the closed end and then seizes in the bore. I used a river of WD on it. My thumb hurts from manipulating the linkage
May have to dig deeper.

I had the same problem with my 21BB slide carb.You gotta make sure you oil it after each run.I had to pry mine loose with a screw driver a couple of times it was stuck so bad and then tap it back in with a small hammer(not recamended).Take the linkage off and twist the slide to the left or right(like a screw) and push it in at the same time.It has a spot that it gets hung up on and when it does it is really hard to get loose again.Also remove the rubber boot and spray some wd40 on the shaft and just keep working it back and forth bye hand and maybe try some after run oil instead of the WD40.Hope this helps it did with mine.

Thanks Rex!
What is funny is that I was using after run oil (down the piston bore) and I just switched to WD (down both bores) due to my T maxxes DVD. If I get it working I will start using on both carb and piston bore. I like the WD cause it seemed to be easier to start vs the oil.
