I have a nitro Rustler with a Fantom .12 engine and just got a Team Associated low end tuned pipe for it, but I'm having problems getting the truck to prime (the finger-over-stinger method) and I have to disconnect the fuel line from the exhaust and blow in it to get the truck to prime, but that's a pain in the butt. What gives?

Try replacing the fuel line with the clear kind so you can see it enter the carb. Then turn the engine over a couple more times. then try to start it. That's what i do to my maxx and it starts everytime.

I already have clear blue fuel lines, so I can see through the lines to see the gas flowing. Also, the only way I can get the fuel from the tank to the carb is if I blow on the tank-to-pipe fuel line, but then it will start then die after a couple seconds. I think the problem is that gas isn't getting sucked out of the tank at all. I've checked the manifold screws, which were a little loose, so I put thread lock on them and tightened 'em up. I checked all the fuel lines to make sure they are connected to the tank, pipe, and carb well. I checked to make sure my fuel filter wasn't dirty. I looked at the L-coupler (it's a peice of crap, but the hobby shop I went to didn't have the exact manifold I want, so I had to use the stock coupler) very well for cracks. I can't think of ANYTHING that could be making it not suck up gas, and it's making me mad. HELP![sm=confused.gif]

How is the engine. Does it still have decent compression.

It's a BRAND NEW engine. I just got done breaking it in the last time I drove it.

hey slacker..i had the same proble last weekend and found a small crack around fill neck of my fuel tank...it looked like it was just a scratch but it was a crack...look the tank over and see if it's not cracked..hope it helps you.

That may be it, 'cause I've pretty much ALWAYS had a problem with the truck priming. It's only worked properly when I first got it and maybe a couple months afterward.

you might also check the cap seal too

Yeah, I've already replaced that before (like, half a year ago) and it didn't help too much.

i think the problem is that your fuel filter inside your tank is cloggled. just go to your lhs and get a new filter

C'MON PEOPLE! I have a NITRO RUSTLER! There is no fuel filter in the tank, and, jkdv8, there is no primer bulb (PM message)! Work with me here.

take the tubes off fill em up with water and chec and see f there leaking

I'll try right now.

Nope, no leaks in the fuel lines. Next test.

I fiound out what was wrong with the truck. I was blowing through the tank-to-pipe line to prime itand I noticed some gas bobbling out of the place where the carb goes into the engine. How do I fix this leak?

first try tightening it, then if that dont work take the carb out, check the o rings you may need to replaced them.

I switched the seal out with the one from my old TRX Pro 15 carb and it fixed it. Now it primes REALLY well (so good that I keep flooding it), and now I just have to work on the tuning and getting used to tuning again, since I haven't driven my truck in about 5 months or so.

Nice, good luck w/ the tuning.

glad to here we all helped again...lol[sm=lol.gif]...glad you found it and got it fixed...let the bashing begin....

P.S. thanks for letting us know what else to look for in that situation..

yeah good luck with it

Weel, of course as soon as I get one problem I run into another problem or two.
