New here and to RC cars. Bought a new Matrix and I'm having some problems.

1. Got the car running and started driving around slow on pavement. The car started stalling at about 1/4 throttle.......it would just shut off like you had hit a kill button. The car did this several times. I assumed it was a problem with the plug. Checked plug....looked good..... but I put in a new one anyway. Same problems with stalling occured. The car became harder and harder to start a which time I realized I had run my igniter down ending my day. VERY FRUSTRATING!
Any ideas?

2. What should the needles be set at for break-in? The manual (if you could call it that) doesn't have this info...or much else for that matter. It doesn't even tell you which of the 4 srews on the carb do what. CENs website has a general FAQ but nothing specific. VERY FRUSTRATING!

3. With the engine not running and the radio on, my throttle servo keeps twitching. Is this normal? Can I fix it?

4. I noticed air bubbles going through the fuel line. Is this normal or does this mean I have a leak somewhere? Maybe causing the stalling?

I've had this car for a month and it's only run 1 minute. I first had to order connectors to make the battery....reciever.....and charger match. All three were different. Now the troubles with stalling. Again you guessed it...VERY FRUSTRATING.

Any help you folks can give would be much appreciated. Thanks.
