Your old tank must of had a small hole in it causing an airleak.

So your old tank had a primer on it but your new one doesn't?

To get fuel to the motor, put your finger over the stinger and turn the motor over a few times (before installing the glow ignitor). You should be able to see the fuel in the lines. Install the ignitor and fire it up.

What happens if that doesn't work?

Someone suggested sucking up the fuel with your mouth and blowing through the pressure line. The pressure line method was unsucessful.

Any ideas how to pump that fuel to the carb? Im lost on this.

Sorry - but the tank with the primer is pointless. The primer is spposed to make it easier to get fuel to the carb prior to starting the engine. Unfortunately, it also allows air to get into the fuel line and causes problems. They all do it.

The thing is - no one needs a primer! Just blow down the pressure pipe and fuel will get to your carb. Then, a quick dab of a finger over the exahust (whilst spinning the engine) helps draw some more fuel if need be. This method primes any engine quicker than with a cheesey priming pump and it doesn't risk troublesome air leaks.

Even tramps know better than to try putting nitro fuel into their mouths!!!

Assuming you have fuel in your tank, just blowing down the pressure pipe will force the fuel in the tank to travel along the fuel line and into the carb. If your carb is set right, your engine will start.

DONT PUT NITRO FUEL INTO YOUR MOUTH!

It's highly toxic and can cause blindness.

I remember i blew the fuel line that hard my head turned into a tomato.

Anyway i've since found the problem though. The engine was worn down to the nickel inside the sleeve.

Thanks

If you have to blow so hard your ears pop, chances are that your LSN (or possibly your HSN too) maybe completely closed off. This will prevent fuel flow and make the engine impossible to prime or start. It will also make your head turn into a tomato.

With the correct needle settings, blowing down the pressure pipe should quickly prime the engine. If you use clear fuel tube, you can easily see the fuel travelling down the tube into the carb.

Another interesting thing you can do to check the carbs needle settings is the 'blow test'. Disconnect the fuel line from the carb, and put a spare piece of tube onto the carb. Blow down the tube, with the throttle in the closed position. Assuming all is well, you can feel resistance as you blow and can hear a slight hiss. Manually open the throttle as you blow, and you should be able to hear the hiss get louder and the resistance should reduce until you hit full throttle.

This can highlight some typical carb related problems, such as needles that aren't set correctly, blockages in the carb - such as dirt etc and O-ring seal type problems too.
