Motor Issue
Hi guys ive got a motor problem and would love some suggestions on how to fix it
When i over prime my motor it starts up no problem and once the fuel in the carby has gone the motor stalls.. there are no blockages that i can tell and ive check my exhaust back pressure already.. so im very confused!!!
Any help would be appreciated. Even the same things ive already checked ill re-check if someone feels confident thats the problem
Thanks!!!

We had a simular scenario at my local offroad track on the weekend, The engine would run when primed but would soon run out of fuel... We started to check for leaks (fuel tank etc) and tried for ages re tuning it, After i had spent half an hour on it another three or four guys looked at it and eventuly one bright spark found that the pressure nipple on top of the tuned pipe where the pressure hose connects was blocked.. after running a small driver thru it and cleaning it out the buggy ran fine
Funny thing is that it was a brand new rtr hyper kit
Anyway you said you checked your backpressure so i guess thats not your problem... Try checking your fuel tank/lines for leaks, put the tank under water and blow into it and make sure no bubbles escape etc

after going through everything with the most care ive ever taken in my life.. there is the smallest most tiny little impossible to detect leak in my fuel tank right up the top where there in no fuel... could this little thing make a difference?! its soooo tiny it makes no difference when priming though!!

Is this a new motor ? Was anything done to it before this issue started ? When i had an issue like this, it was a piece of the oring from on of the carb needles block in the fuel path.
