Looking at the pic, it appears the box has adjustment to go back at least an inch. Failing that, and assuming a usable mag is either not available or hugely expensive, I'd either alter the engine plates to tilt / raise the engine slightly or alter the box mountings to give sufficient clearance.

Hi Jools,
What about a short chain and sprockets to a mag on a platform mounted outside the timing case? Mag fore and aft
I have seen some photos of other Howard's but I believe the engine is a low rpm unit so don't expect to break any speed records *smile*
BTY, i have a Howard with a 600cc sv J.A.P

Wico/Wipac made some short magnetos.

Here’s one on a Wolseley engine.


Or, perhaps you could mount the magneto behind the gearbox, driven by a shaft passing over the top of the box.

TT - got one of those mags on my Ransomes pump (sv 600cc japanese engine). The impulse starter device really helps starting, but not aware if they made twin cyl versions.

I see the spellchecker has done it again. despite writing Joseph   Arthur  Prestwich  it got converted to 'japanese'.
