Go to the Archive indexAs with all small two stroke motors, it is recommended that during restoration and renovation, as well as attention to the magneto and compression, the oil seals and bearings are also changed. Due to the technicalities of the two stroke engine and the ‘sump’ acting as a pressure vessel, it is necessary for the ‘sump’ to be gas tight. Crankcase seals therefore are most important in this respect.
To help fellow Mini-Motor owners, since ours has recently received the bearing/bush treatment after the Stowmarket run on which it performed less than satisfactorily (it now performs admirably), the following are the items obtained from our local dealers (Bearing Services Ltd—but Edmunds Walker are probably just as good and I am sure there are other similar places).
Total cost about £20—for a world of difference.
