The OS LA series
Bill, I've read your comments before on the MDS engines, I'm glad you've had a good experience with them. It seems that both MDS and the OS LA series provoke strong arguments with many users.
I've not owned a MDS so I won't comment either way on that, but I think the LHS (local to me) that did sell them is going to stop based on comments from customers.
I could have quite justifiably thrown my engine in the trash and not bought another LA based on my experience with the 65. But I didn't, I perseveared with it and have been pleased with the other LA's that I have.
In future, I will try to buy what I believe are 'quality' engines. This leaves both the LA and the MDS out of the scope (no favoritism).
Hence my next choice of Irvine...
