The inventive device includes an ignition assembly support for mounting an ignition distributor on a combustion engine and further including a drive assembly for transferring the rotational movement of the camshaft of the combustion engine to the ignition assembly. The ignition assembly support is mounted on the exterior of the combustion engine and has a sleeve member for receiving the cylindrical mounting portion of an ignition distributor so that the distributor is supported external to the engine. ## Claims ### Claim 1 An Ignition Assembly Adaptel System permitting the use of an ignition assembly on a combustion engine having a camshaft, said ignition assembly being of the type having an ignition distributor with a cylindrical mounting portion housing a rotor, said adapter system comprising: an ignition assembly support for supporting an ignition distributor in a position external to a said combustion engine, said ignition assembly support comprising an adapter base plate and a sleeve member fixedly united together for mounting on the exterior of a combustion engine at a location adjacent to the camshaft of said combustion engine, said sleeve member having an interior passage for receiving the cylindrical mounting portion of an ignition distributor, said adapter base plate having an annular aperture therethrough and opening into the interior passage of said sleeve member, and a drive assembly for transferring rotational motion of the camshaft of said combustion engine to an ignition distributor received in the sleeve member of said ignition assembly support, said drive assembly being mountable to an end of said camshaft for rotation therewith and being connectable to the rotor in the cylindrical mounting portion of said ignition distributor such that said drive assembly transmits rotation of said camshaft to the rotor of said ignition distributor. ### Claim 2 (depends on 1) The Ignition Assembly Adapter System of claim 1 wherein said drive assembly comprises a drive rod having a threaded end portion for being threadably received in an end of the camshaft of a combustion engine. ### Claim 3 (depends on 2) The Ignition Assembly Adapter System of claim 2 wherein said drive rod has a hexagonal shaped end portion opposite said threaded end portion, said hexagonal end portion being for engaging the rotor of said ignition distributor. ### Claim 4 (depends on 3) The ignition assembly adapter system of claim 3 wherein said drive rod comprises a threaded drive bolt member and a hexagonal drive shaft member, said drive bolt member having a head portion with a recess therein for receiving an end of said drive shaft member. ### Claim 5 (depends on 1) The Ignition Assembly Adapter System of claim 1 wherein the combustion engine includes an oil pan for receiving engine oil, and wherein said ignition assembly support additionally comprises a drain conduit in communication with the interior passage of said sleeve member and also in communication with the oil pan of said engine to permit any engine oil entering said interior passage to drain from said interior passage to said oil pan. ### Claim 6 (depends on 5) The Ignition Assembly Adapter System of claim 5 wherein said drain conduit comprises a drain tube fixedly united to said sleeve member and a flexible drain hose connected to said drain tube and connected to the oil pan of said engine. ### Claim 7 (depends on 1) The ignition assembly adapter system of claim 1 wherein said ignition assembly support additionally comprises a hold down bracket mounted on the sleeve member thereof for attaching to a hold down tab on the cylindrical mounting portion of said ignition distributor.
