G'day BenK,

Info on the old Kirby engines is a bit scarce these days, but there is an exploded diagram of the HK25 [from the Victa 'Green Book'] in this thread: https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=72511 The part numbers given are Kirby, not Victa, FWIW.

And the basic ignition settings

Of the commonly replaced carby parts the float, bowl seal and bowl drain are available as Tecumseh parts. The needle and seat seem to be a bit more difficult to find equivalents for.

But as BB says, it's easier and probably cheaper to get a new carby nowadays. Look for a Tecumseh H25 carby, if you have a HK25.

Cheers,
Gadge
