To determine which one is right for your engine and carburetor, first determine the type of carburetor flange you’ve got. There are plenty of carburetor base plate gasket options available. For instance, you may need to raise your carburetor body up a bit to provide room for vacuum ports or, conversely, opt for a thinner gasket to ensure proper hood clearance. By creating more isolation between those two mating surfaces, a good carb base plate gasket can mitigate a lot of heat soak coming from the engine-which can go a long way to prevent nagging fuel delivery problems like vapor lock.Īnd while carb mounting gasket thickness is often associated with its ability to block heat, there are a few other factors that need to be considered when selecting the thickness of your carburetor gasket. A leaky carb seal also makes it really difficult to properly tune your carburetor and can contribute to a ton of other engine issues, including things like a poor idle, hesitation upon acceleration, and a loss of top-end power.Ī carb mounting gasket can also act as a thermal barrier between a baking-hot intake manifold and the carburetor flange. A proper seal is very important here, because even a small leak can greatly affect the way your carbureted engine performs. For starters, a good carb mounting gasket will ensure an airtight seal between the carburetor body and the intake manifold. The tightening sequence is usually from the centre of the manifold outwards to the ends.While it may look relatively simple, a carburetor base plate gasket does a few very important jobs. ![]() Tighten the nuts on the manifold, using aĪdjusted to the setting recommended in the car service manual. Reassembly is in the reverse order of removal. On each side of the gasket, because the larger water passages are more prone to leakage. Some water-heated intake manifolds, particularly on On someĪ gasket may be in two or three pieces, or inserts may be fitted be sure all parts are properly aligned. If it is, replace it.Ī new gasket, making sure that it is the right way round, with all holes lined up. Do not allow particles to fall into the manifold or the cylinder head.Ĭheck the manifold to see that it is not cracked or damaged check its face with a straight edge - such as a steel ruler - to see that it is not warped. With the manifold off, carefully scrape all gasket-mounting surfaces clean of dirt and bits of the old gasket. If any manifoldĪre broken or damaged, remove them using self-locking grips, two nuts and a spanner, or stud remover. When the nuts or bolts are removed, the remains of the old gasket may cause the manifold to stick: tap the manifold with a rawhide hammer to loosen it. To all nuts or bolts which have to be undone, including the Has a V-configuration, there will be exhaust manifolds on the outer side of eachīank, but probably just one intake manifold located in the centre of the V. , or they may be combined or bolted close together. The intake and exhaust manifolds may be on opposite sides of the A 'blown' exhaust gasket can be detected by excessive noise from the exhaust, and by white burn marks around the ![]()
