Thanks for the tips. I searched the model and couldnt find the starter via Parts Tree but I found a very similar one which confirms the position of the second washer similar to the advice provided by mark.

Can anybody confirm if the washer that goes under the retainer is a special type. Gagde I think you mentioned it was a friction washer. I just want to make sure I havent got things mixed up. I have a feeling the friction washer is so warn the starter wont engage.

Lastly does anybody know the best place to purchase friction washers, if thats in fact what they are.

Thanks
Peter
