Yes they are when you put your finger over the exhuast the fuel will go about half way and you can see bubbles in the fuel tankAre the fuel and pressure lines hooked up in the correct places?
Gasket is good for sure and I didn't take the lines off the tank just from the exhuast and carburetorPossibly air leak check the seal on the fuel tank.
Were so good that you just have to look at us and it's fixed itself. Or you've scared them away and they've read the manual...Yeah, but it's working now, right? We're good. We're REALLY good.
I have the same problem but I'm building a nitro sled and I can't figure out y My fuel won't feed this is the Rc I builtI have an associated 8.2 with a werks b5 and I took everything off the other day to clean it good....when I put it back together it will not get any fuel its sucking air somewhere and won't prime up any suggestions
This is my project an rc snowmobile and I have the same issue my fuel won't primer be stay feeding, tried 3 Differnt fuel tanks and replaced lines, if u look in the picture my header is twice as long as normal to fit my application would that have an effect ?I have an associated 8.2 with a werks b5 and I took everything off the other day to clean it good....when I put it back together it will not get any fuel its sucking air somewhere and won't prime up any suggestions
That is one mental exhaust try replacing it back to stock and I reckon it'll workI have the same problem but I'm building a nitro sled and I can't figure out y My fuel won't feed this is the Rc I built

What could cause the fuel not to feed? Like do u think cause the header is longer the pressure back to the fuel tank is not as high? I think if there's not exhaust leaks it should be fine?That is one mental exhaust try replacing it back to stock and I reckon it'll work

Try going back to stock exhaust, but its probably pressure and a combination of other things, and the problems won't end here- you'll never get the engine to run or tune properly either...What could cause the fuel not to feed?

Y wouldn't I be able to ever get it to tune properly?Try going back to stock exhaust, but its probably pressure and a combination of other things, and the problems won't end here- you'll never get the engine to run or tune properly either...
Nitro engines are very sensitive, the slightest temperature changes can cause a complete retune to be necessary, the same applies to exhausts. Changing header lengths, stinger lengths, amount of bends, amount of chambers, angle of deflector on the end of the exhaust- loads of things, some being negative, effect performance. If you go changing things like header lengths, bends and all that, your decreasing performance, that's why all nitro engines and exhaust follow pretty much the same format, and any changes that have been done would of had hours of planning and tests just to alter a minute lengthY wouldn't I be able to ever get it to tune properly?
Well I'm not to worried about the performance like she should still rip decently, this morning I tried priming and it primed but I didn't try and start it, had to leave for work but will it continue to feed is the question, I've had it run in and it sounds mean and like its idles nice but it's always the fuel that is either stopped feeding or is leanNitro engines are very sensitive, the slightest temperature changes can cause a complete retune to be necessary, the same applies to exhausts.

If its too lean, the carb will heat and you'll get vapour lock- where the fuel evaporates in the carb causing fuel to back up, so are you saying with the stock exhaust it ran? And the performance issues may be quite bad, you may have to end up damaging the engine just getting it to run- that's if it will run...Well I'm not to worried about the performance like she should still rip decently, this morning I tried priming and it primed but I didn't try and start it, had to leave for work but will it continue to feed is the question, I've had it run in and it sounds mean and like its idles nice but it's always the fuel that is either stopped feeding or is lean
