My Jato has a clog somewhere in the fuel lines or the carb. I fill it up with fuel try to start it up but no fuel is moving, how do I take apart the carb and clean it out?

BTW I resetted the HSN and LSN to stock settings and that wasn't the problem either.

I'm also using Blue Thunder 20% for fuel if that helps at all.

Check the fuel tank for leaks. That might be the problem.

BTW what hobby shop do you go to? I see you are from New Orleans. I'm not too far away.
 
I'd check the tubes and make sure they are not obstructed, or just replace them and forget it. Does it start if you prime the carb directly?
 
Samrsnow I don't go to any hobby shops I usually went to Westbank Hobbies but they don't like me coming around since I bought my Jato off of tower hobbies and they think I ask too many questions. I'd go to Hobby Hut but it's quite a distance from where I live since I live on the westbank I say N.O. cause I'm only 10-15 minutes away. It's bone stock, I check the fuel tube and don't see any obstructions, I can remove the end by the carb but the other end gives me problems so I can't check that end. How do I prime the carb directly? I usually prime with my finger on the exhuast pipe and doesn't do a thing.

Try taking off the pressure line and blow into the line and see if fuel goes to the carb. I find that it a better way of priming the engine.

And man those guys at westbank hobbies don't sound so nice if you ask me...

i wish you could bring that jato over to me so i could take a look at it but i guess i'm too far away....I'm only 2 mins from the hobby hut.

I can meet you at hobby hut on saturday if you wanna take a look at it. I work from 8am - 430pm mon through fri and I'm dead tired after work. I agree with you about westbank hobbies I'll have to take visits to hobby hut once in awhile to do my glow plugs and fuel shopping.

Draggo, I can't meet you at the hobby hut on saturday because I am going to a LSU baseball game.

But when you get the chance. Take out the fuel line off the tank (not the one from the pipe) and put you're finger over the little nipple and then blow into the line. If you cannot blow any air into it then there is no leak. So when you prime it next time blow into the line and fuel should shoot into the carb.
 
If you're willing to deal with a little mess, do this. Take it outside. Remove the fuel tube from the carburetor only. Then remove the pressure line from the exhaust pipe only. Point the fuel side away from anything. Then blow into the pressure line. If fuel shoots out of the fuel line easily, then you know the problem is most likely in the carb. If it doesn't, you know the issue is either the fuel and pressure lines. Or it's entirely possible that there may have been some plastic flakes left in the fuel tank from the manufacturing process that may have blocked the fuel outlet in the bottom of the tank.

Let us know what happens when you try some of these tests and we'll see if we can pinpoint it better.
 
hey, you should probably check the filter inside the tank to make sure that it is not blocked
 
ok I blew into the pressure line and fuel came out of the fuel line. I attached the fuel line into the carb and tried to start it by blowing pressure into it and it started trying to start up. I attached the pressure line to the exhaust, filled up the tank and got it to fire up. Jato is back up and running, thanks alot for the help guys.
 
You can. That'll minimize the chance of a leak at the fittings. It's just a pain the ass when you need to pull the lines for maintenance.
 
Great another problem arised, when I start my Jato it automatically floors it even when the reciever and transmitter is turned off. I messed with the HSN and LSN nothing changes. I tried different settings on the transmitter and it still does it, Anybody help me figure this out?
 
Sounds like you are not getting enough fuel, first you have a problem getting fuel. And a lean condition will cause high revs. So it sounds like you only solved half of you problem, instead on no fuel you are only getting half of what you need! I would replace your fuel lines and fuel filter, and see where you are.
 
Ok, this time, start by returning the LSN and HSN to factory settings. Then, unhook the throttle linkage because you'll want to manually manipulate the carb. Remove the air filter. Manually close the carb. Adjust the idle stop screw until there is only a 1mm gap in the carb body when the throttle is completely closed. Then start the engine and see how it responds to manual throttle control. That way, you're ruling out the radio as a source of the issue and by returning the needles to factory settings you're ruling out mis-adjusted needles.
 
You could have a transmitter or reciver problem. When that happened to me it was because the batteries in my jato were dead
