{"product_id":"the-single-port-vw-beetle-carburettor","title":"The Single Port | 30\/31 PICT-3 Air-Cooled Carburettor for VW Beetle","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eAn Air-Cooled Engine Tells You Everything Through Its Carburettor. A Beetle that hesitates off idle, hunts at a steady cruise or refuses to settle to a clean tickover is usually describing a worn throttle shaft, a perished diaphragm or a float that has drifted. Replacing the unit is often faster than rebuilding one that has been apart twice already.\u003c\/p\u003e\n\u003cp\u003eBuilt for the single-port manifold. This is a 30\/31 PICT-3 unit intended for the single-port manifold configuration, supplied with the gasket so the installation is a straight swap rather than another parts order. Interchange numbers 113129029A and 113 129 031 are the references it is built to, which is what matters when you are matching a part to a car that has been through several owners.\u003c\/p\u003e\n\u003cp\u003eSpecified as a complete replacement rather than a kit of pieces. The body is a high-performance replacement casting, weighs around 2.5 kilograms as shipped, and measures roughly 20.5 centimetres long by 17.5 wide by 15 high, so it matches the manifold footprint the original occupied.\u003c\/p\u003e\n\u003cp\u003eFitment on an air-cooled engine is a mechanical job, but the setup is not. Tell us the engine displacement, the distributor and whether the car runs a mechanical or vacuum advance, and we will confirm which variant suits your build before it leaves.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eA carburettor is not a part.

Restoration shops use it when the original casting is beyond economic rebuild and the customer wants to drive this season rather than next. Kit car and sand rail builders choose it because the 30\/31 PICT-3 unit is the known quantity in the air-cooled world, with a jetting baseline that a competent engine builder can work from. Owners who have chased a running fault across ignition, fuel pump and valve clearances often find the carburettor was the one component never properly replaced.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq\" style=\"margin-top:32px;\"\u003e\n\u003ch3 style=\"font-size:20px;margin-bottom:16px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:16px;\"\u003e\n\u003cp style=\"font-weight:600;margin:0 0 4px 0;\"\u003eQ: Which part numbers does it replace?\u003c\/p\u003e\n\u003cp style=\"margin:0;color:#555;\"\u003eA: It is built to the 113129029A and 113 129 031 references for a 30\/31 PICT-3 single-port application.
