Hey guys i have 2 sh.18 one is brand new in the box the other one about month old with a week old carb, both of the carbs are locking up this is my 3rd carb that has locked up! the sh.18 brand new haven't takin it out of the box the carb was nice and loose just like the one i order from yall about 2 weeks ago, with end 5 tanks more or less i have had 2 carb lock up they still move but there not loose enough for the servo to move them? i dunno what else to do!! i have adjusted the servo i have replaced the carb once all ready and they still just keep locking up, thats 24.99 a carb this is my 3rd one!! i also talked to mike about my lightning about the idle screw not working!! the lightning was brand new not even 2 tanks of gas threw it, i worked with it for about 30 mins and got it working but now its doing the same as the sh.18 carbs its not as tight as the sh.18, all in a summary so when i adjust the servo and i adjust the carb the thottle still sticks and runs high rpm intill i press my brake on all 3 of my redcats the lightning and my 2 volcanos

and one more thing is i do use after run oil in all my cars!!

Justin : the only things that oculd make the carburetor stick are : dirt or lack of oil. It's possible your fuel may be bad.. sitting in the sun, or heat is bad for fuel. If thats not the case its possible something got in there. Take the carb apart, clean it and put it back together with a little after run oil or 3in1 oil.

If both of these are not the case, its possible the tension on your throttle return spring isnt set right. If you move the collet forward to increase the tension of your spring, it may help with closing the carb when you go back to neutral.

i have tried to move the spring forward about far as it can go and on the sh.18 will the carb break all the way down like the .16 on the lightning i have cleaned both carbs the lightning is better than the sh.18 but just seems to be still hard for it to move

Lightning fixed

no luck on the sh.18 carbs can they be totally brokin down like the .16 carbs

got some 3 and 1 oil still hanging up is there any way to break them all the way down?

Justin have you been running air filter oil?

yup got that too!! i dunno whats the deal with this thing but getting tired of them it will be my 3rd one!!

you think that maybe your servo is going too far and thats why its getting stuck.

nope adjust everything much as i can sick of my volcano am am selling it !!

you can pull the sleeve out of the carburetor, have you gotten it that far apart? You may need to spray it out with some electric motor cleaner, or brake cleaner before oiling it.

i can not pull the sleeve out wish i could or i could fix it i got it pretty loose then 1.2 throttle it got stuck and wreacked it bent up my exhast.. pretty good i have tried the brake clean and 3 and 1 still can't get anything to work very disapointed

know the .16 sleeve will come out but no luck with the .18

You have to remove the idle screw to get the sleeve to come out.

i finally got one part and its nice and loose now, but as for the other carb its shot can't get it to free up!! guess just have to buy another one.

For all the money you have spent on these carbs you could of bought a better motor.Throw them motors away and look on fleabay for a hpi 15or18 much better motors than the sh or vx.I have had both and both are nothing but problems.

yea going to upgrade my motor soon in my lightning prob will try out the hpi!!
