Engine overhaul - video 05 install the distributor drive shaft This is the continuation of video 04, we are now going to install the distributor drive shaft, both on an already rebuilt Volkswagen Type 1 engine and on a split Type 1 crankcase. We pay a lot of attention to the correct positioning of the drive shaft at the beginning of this video series, because it is crucial to be able to adjust the ignition properly, later, when the engine is overhauled.
HPMX carburetors The most famous double carburettors are the Weber IDF and the Dellorto DRLA. Since a few years there is a new player on the market, namely the HPMX carburettor. This is marketed by EMPI and is also sold as a complete set, including manifolds, air filters, linkage and mounting material.
Engine diagnostics - video 02 BONUS defective rockers arm parts In video two of this series, we measured the rocker arm parts, and compared them to the wear limits listed by the VW workshop manual. In this video, we will show examples of rocker arm parts that are in less good condition than these of our AB 1300 engine from video two. This should help, to better diagnose the rocker arm parts.
air filter preheating It seems to be a natural part of your air-cooled engine, but the air filter plays a crucial role, it's like breathing in a human being. The carburettor is tasked with mixing petrol with air to deliver a flammable mixture. Petrol alone is not a good fuel. That requires oxygen and not just a little bit of it.
Engine diagnostics - video 04 part 2 valves and valve springs In the second and third parts of this video, we will measure valve spring pressure. We begin in part 2 by measuring the valve spring pressure at open valve. Also known as the valve spring pressure at maximum valve lift. In part 3, we will measure the valve spring pressure at installed length.
Engine overhaul - video 08 ignition time of cylinder 1 In this video we will determine the ignition timing of cylinder 1. This mark will be needed to correctly position the distributor drive shaft during assembly, as well as for ignition advance adjustment once the Type 1 Volkswagen engine is rebuilt.
Engine diagnostics - video 03 pushrods In video fourteen of our series on engine overhaul, we disassembled and reassembled the rocker arms and pushrods. In this video, we will inspect the pushrods. The result of this diagnosis, will tell us if we can reinsert the pushrods, or if we need to replace them.
