So I have an HSP 1/10 scale warhead buggy and I haven't used it for about 5 months. I tried to get it going but I couldn't prime the buggy to get fuel into the carb. The only way I could move the fuel to the carb is by blowing into the tube that is connected to the exhaust. When I do this I am able to start the buggy and it runs for about 5 seconds with barely any smoke then dies down because no fuel is getting to the engine. It also gets VERY hot. To get it going again I would have to blow into the fuel line to move the fuel so it can run for another 5 seconds. My fuel lines are fine but it is quite loosely attached to the exhaust pipe due to the way the whole is structured. My exhaust gasket is broken but I tightened it pretty tight so I think it should be fine. Does anyone know how to fix this problem so I can prime my car and also get fuel flowing to the engine?
Thanks so much for your help.

You likely have a blockage from fuel that's turned to gel somewhere in the tank, tubing, or carb.

You may want to put small zip ties around your fuel inlets and outlets and check to see if your gas tank is ok, ( no cracks, good seals and no leaks when full) make sure your fuel lines are good, one crack can hurt suction to the carb. Good luck and post up results so someone else can ,learn from this as well, also see if you have a filter in the tank or outside the tank and or replace both

Also I can get the fuel to flow if i over the carb hole and full the trigger without putting my finger the exhaust hole. So I think the main issue is that my exhaust isnt creating enough pressure to push the fuel into the carb. Any further tips?

I went through this today with a car that had been sitting for over a year, I just kept blowing into the carb, I did the same as you and put fuel into the carb and it started up. Check your fuel line. I even put a little fuel in the line leading to the carb and I blew into the carb. Like others said, make sure the tank lid has a good seal.

That's possible. It's best to replace the 2 rubber gaskets in that case.

I think you answered your own question in your original post. You said your exhaust gasket is broken. That can cause major tuning problems. Years ago I was having all kinds of trouble getting my truggy to run. In the end it turned out that I just needed to replace the rubber gasket between the head pipe and the engine. Once replaced, the engine ran great again 😎
