Okay, I get my car runnin pretty easily, but when I accelerate it dies? Ive never had this prob. before. What is wrong? what should I do?

now, the engine doesnt die, but it putters down, loses speed and makes a real wierd puttering sound

.

If it bogs when you give it gas, it's more than likely running overly rich.

lean out the engine 1/8 of a turn to the right until it gives you smooth accelaration. The engine bogs down and is dying because by setting the main needle to rich you are flooding the engine.

Okay, I ll give it a try. I will tell you what happens. thanks

leaning it out, only made it worse. I richened it a little though, and its running now, but isnt going as fast as it did

what kind of engine you got?
did you buy kit new?

its an OS 12 cv-x I bought it used, but it was pretty new when I bought it. Why do you ask?

ow i had the os cv-x and i had the same problem, it has to do with the third needle. when i had this problem i just took it to my local hobby shop and they tuned the third needle correctly from its stock position and it ran just fine. i suggest that you do the same thing.

just wondering what the heat sink was.........I have an OS CVX with stock head

Let them tune it? Were talkin about a hobby car.. not his daily driver!!

Whats the fun in him doing it for ya? LEarn it the hard way! You cant break anything..

My engine was giving me hell.. but I am starting to understand it pretty well and nw I can listen to it and tell if its rich or lean.

Practice is the key! Dont let other do it for you!

Thats my approach anyway

ram

im just saying let the hobby shop guy show him how to do it, so the problem can get fixed, then he will know how to fix the problem if anything like this happens again.

my engine did the same exact thing it continued doing for a week
does the motor not want to start after dies?

yup, almost like I have to wait for it too cool down!!

my motor doing the same thing im not sure what the problem is but my motor wont start at all ive tried taking it apart and siliconing the carb the back plate nothing works so im gonna
send it to hpi with $100 and get a ss motor meanwhile i'm gonna
buy xtm18.

Jsswcks,

It you want to save yourself a little bit of money, keep the motor you have (I assume it's a 15FE) and buy HPI's stage 2 upgrade kit for $60.00. You get the 5.5 2 needle carb and the ABC piston/sleeve/rod combo. With those upgrades, the 15FE becomes a 15SS and you save $40.00 in the process.

You know, I don't really think that the HPI exchange program is as hot a deal as it appears. You send them your motor and for $100.00, they send you a 15SS. Spend and extra $20.00 or so and you can keep your current motor as a backup and still buy an OS or something like that. Just something you may want to consider.

ok thanks

how long has it taken for you to get your .15 SS because i've been waiting for about 7 days and it still hasnt showed up in the mail.

i just sent it off but it probably take 3to4 weeks from the time u sent it.

If it is not responding to adjustments, start fresh by
cleaning the carb. Its either fuel or glow, thats all these are.

Have patience and avoid overheating.
