Subject: Re: M45 Distributor Skew Gear
Like so many things in life I think there are a number of factors that often work against you. I firstly tried to get the original Rotax to work but there is a shortage of reliable consumables and I suspect the distributor cap is a weakness. Marin Jay's advice was to go with a new distributor complete where the cap, condenser, points are all known to be good, I agree with Mark that as the shaft is in constant drive you would anticipate little variation but in practise I wonder. Anyhow the result is the key, and I am delighted, and the predicted 20% performance drop was not evident and even under load "distributor only" was not a problem. The other aspect that need some work was to make sure the advance and retard for thew magneto and distributor was matched, in my case taking all the slack out distributor cables and levers. What you need to achieve is a reliable stop when fully advanced. I do think all the effort was worthwhile. Regards, Stephen
