On many dual systems you start on the magneto and then switch on the second ignition system (as it has no starting retard). Will, would we be able to borrow the head with second ignition holes?...We have a spare set of heads that we want to get re-engineered to include dual plugs cheers Rob

Modification of a 6mm (?) - long handle alen key is required to make it very easy and take off the RH air filter along with throttle and choke assembly rods and bob's your uncle. Have taken ours out 3 times now with no real difficulty. I sent ours to Ian at Aviation Intrument and Electrical Services, Building 2, Second St, Moorabin Airport, Mentone, VIC, 3194 - 03 95871652. There have been a couple questions asked about dual ignition - we have a dual ignition setup which is merely a back up and I think it cannot be certified as it is an automotive unit and I am not sure you can retard the spark like an impulse coupling on a mag for startup - hence mag still required? (Dimona expert needed here to confirm). Also people want to drill new holes in the head and we will have a spare head off our old engine that we will send to Nigel Baker and people could use as a template. Our engine had the exhaust valve head fall off in cylinder 4 and upon landing cylinder 4 was not in the engine! Hence we are buying a new engine and have a spare head with no pot.

The L2000 is single ignition, so flying to the nearesr airport may not be an option following a mag failure! In a single ignition engine the mag needs to be inspected also at 250 hours. It is supposed to be possible to change the mag without removing the engine, but don't know how.

A good magneto (especially with a jet of cool air onto case) is TOTALLY reliable and that is what you want. Our Sauer manual says "if magneto fails fly to nearest airport and have it repaired but if electronic ignition fails then flow to your home airfield and repair then" Also I think you would loose your certification with electronic ignition. It might be old technology and heavy but it is reliable That is my thoughts Ian McPhee On 21 June 2011 06:22, Lasse Schmidt <[email protected]> wrote: Hi all! I´m just about to do a 500hr service in my magneto. Whilst looking at this big heavy piece of sparklemachine the idea stuck me that it would be more fun to use electronic ignition. Is there any available for the Limbach L2000? Also - is there any easy way to remove the magneto or does the engine have to be removed? Thanks!
