Engine not getting fuel

[adumm]

Hi

I'm a noob when it comes RC's I had a problem where my car (Thunder Tiger Tomo BX 2WD) would start but then die as soon as the glow starter was removed, later found out my fuel tank had a small leak.

So today I bought a new one fitted connected up the fuel leads, and can I hell get the nitro to travel up that tube
I've tried putting my finger over the exhaust and pulling the starter motor, nada nothing, zip no suction at all .

So i thought what happens if i blow up the exhaust fuel line , nada nothing & zip no fuel moving at all and no air blowing out the tank so its tight,
I then while blowing up the fuel line loosened the HSN until I got fuel moving and its practically 1/8 of a turn before it comes all the way out which can't be normal.

Since then I have removed the whole engine and exhaust and checked for cracks leaks etc can't find sign of any at all.

Reconnect & zip tied the exhaust on still nothing.

I know I am probably missing something obv any ideas?

Try cleaning your carb and needles.

Sounds like you may have the lines backward. It's not suction from the engine that moves the fuel,it's pressure from the exhaust. Make sure the line from the pipe goes in the top of the tank and the bottom from the tank goes to the carb.

They deffo the right way round,
But to check you mean the one on top of the fuel cap goes to exhaust and the silver one lower down on the corner goes to engine?

does fuel go through if you remove the fuel line from the engine and blow through the exhaust line

Yes, fuel should flow when you blow through the ex. line. If it does not, there is a blockage. Something is funky with the carby. I agree with an earlier post. I'd try taking the carby apart and clean it. Make sure your fuel filter is clean too. The needle should not come all the way out at 1/8 turn. Does fuel flow if the line is removed from the carby and then blow through the ex.? If not, that will localize the problem to the fuel tank and components associated with the fuel tank. If it does flow, then you'll need to do something with the carby... Clean it first and go from there.

Help

Try check if the exhaust is pumping the fuel:\
