VW1834 and Slick 4001 Mags

Dear All,

Have recently purchased an homebuilt that has an 1834VW with twin Slick 4001
impulse magnetos. Nice.

I know that a manual used to be available for this magneto, but I have been
unable to get hold of a copy. Does anyone either have a copy that I could
have a copy of (if you see what I mean) or know where a pdf copy is.....just
wondering.

Actually, what I would like to know is some service information, like what
is the correct points gap and 'e-gap' setting?

Also, what plugs/plug gap do you recommend for this engine/magneto
combination?

Any and all help most gratefully received.

Thanks in advance,

Michael.
