we had a long weekend so I managed a few more hours in UDT

Hi Paul The carb is on top. The oil feed to the manifold is also from the top, whilst the oil cooler feed is from the pump at the front (prop hub-side) of the engine. It seems to me that I should be able to link the inverted system (Chirsten valve) to the in-flow side of the pump (can i do it by way...

Hi Paul Certainly The engine is a 2.1 Aerovee The original Zenith KLP Dual ignition - top spark plugs fire on the Surefire electronic ignition which is fitted on the distributor drive shaft; the bottom plugs on a Le Burg (single) system (Tom Heaslip at the time of fitting the electronic ignition cou...

Dear Niel and Paul Complex :shock: I am putting together my shopping list. Niel, am dead sure to fit the breather system - i am just getting to much oil on the outside after every flight :? So may i ask if you could please take you up on the offer for a breather system? I have many more questions bu...
