Brand new MT won't start at all:(

[thejones]

I did everything by the book and it won't even give a hint of wanting to start at all. Don't know what else to do.

If you did everything by the book, I take that you have

- fresh mixed fuel at a ratio of 25/1
- carb at factory settings: 1-1/4 L 1-1/2 H
- primed the bulb on the carb
- choke on until engine pop (2-3 pulls) then choke off to 2-3 pulls to start

If you have done the above, do you have a spark?

 

[thejones]

No idea. How do I check for a spark?

 

[designed2survive]

Before checking for spark have you done what I mentioned above?

 

[thejones]

Yes I have.

 

[designed2survive]

@thejones Try what he does between 1min 20s and 1min 45s

 

[thejones]

I got the exact same spark plug tester. The cord makes the tester spark. So then I decided to try and make the spark plug spark and it sparked also. I'm at a loss.

 

[designed2survive]

That's good news! At least your coil is good and spark plug are good!

Now let's make sure you carb is set properly.

1- Locate the HSN (high speed needle) and LSN (low speed needle) on your carb. Fully close (clockwise) both needles. Do not tighten them. They just need to sit closed, not tighten.

2- open (counterclockwise) the HSN to 1-1/2 full turn.

3- open (counterclockwise) the LSN to 1-1/4 full turn.

After that try starting the engine.

1- prime bulb on the carb

2- choke on, pull 2-3 times until the engine pops. Do not pull too many times or you will flood the engine.

3- choke off, pull 1-3 times to start.

I need to ask if you have pulled too many times before, when you were trying to start it on your own. If you did, the engine is probably flooded. It will not start if that's the case and we will need to take care of that first.

 

[thejones]

I did the needle thing last night. I pulled the cord a bunch of times. Hurt my shoulder.

 

[designed2survive]

Alright

1- take out the spark plug
2- cover the spark plug hole with a rag
3- flip the car upside down
4- pull until you have cleared all fuel from the cylinder.

Then follow start up procedure.

If you have already done so, please let me know.

I beamed a flashlight through the hole and didn't see any extreme wetness, only dampness. Does that still mean that it could be flooded?

Sounds familiar..... I had the same issue as you when I got mine. The carb was junk. Bought a real Walbro and fires every time now. Then told Redcat it was the carb and they sent a new one... too little too late

 

[thejones]

I looked up Walbro on Ebay and found a bunch of them. Which model did you get? Did it just fit onto the engine without any mods?

I would be careful with ebay ones as they could be clones like the redcat one. I'll find the one I got

best price I found was here...

Gizmomotors, WT-990 (it has no choke but I've never needed it) It starts 2-3 pulls everytime.

Buy a WT668 with a choke.
The 990 is the same carb without a choke and is a pain to start.
I'm giving one away to anyone willing to pay the postage

Doesn't hurt to do it still.

If you choose to get a different carb, do not get the WT 990 in your case. Chokeless carb start up is not a big deal but it will be one less thing for you to deal with if you get a Walbro WT 668.

Check this link for the carb. You might wanna bookmark the site too. That's where most people get their general 1/5th scale parts.

It can be frustrating, but don't give up. Once you get it up and going it's rewarding.

Customer support suggested removing the gas cap and if it hisses at me to make the hole a little bigger. It hissed and I made the hole bigger and still nothing. Is there a way to tell if the engine is flooded by looking at it without tipping the truck up and making a mess.

 

[Phill]

Spray a bit of starter fluid in through the air filter.
If it's flooded that should start it and clear it out

 

[thejones]

But how do I know if it's flooded? Is there a way of visually telling if the engine is flooded?
