    RE: just a quick question

    I agree, does sounds like you've got a leak. First place I would check would be the little blue rubber coupling between the exhaust header and muffler. It shouldn't have any holes or tears in it. It should two tie-wraps, one to clampit to the header and one to clamp it to the muffler.

    Also check to make sure the header flange screws are tighten down.

    but the header flange screws? im not exactly sure what those are? ive only been in this hobby a year but im obsessed lol getting my next RC this monday also could a bad manifold gasket be the cause aswell?

    RE: just a quick question

    There are two small screws that attached the exhaust header to the engine block, your manifold gasket goes between the header manifold and the engine block, so the two screws I'm talking about also hold the manifold gasket in place.

    RE: just a quick question

    Missing pullstart screw won't cause the leak, but should be replaced. Sounds like maybe you should retighten all the nuts and bolts. Get yourself some blue locktite and use it on the screws to help hold them tight for a longer period time. Go thru the entire car and remove one screw at a time, put blue locktitre on it, and reinstall snuggly. Be careful not to over tighten and strip out the hole.

    Remove the muffler, hold your finger over the exhuast pipe, and blow into the end with the rubber coupler. It should not leak air.
