Howard Gem 360 twin plugs

Hi All,
Looking for a recommendation on suitable spark plugs for the Gem twin 360 degree engine,
close to finally getting it to run.

Regards,

Hi there
Howard recommended KLG F50 or equivalent with a gap of .025″

Hope this helps.

we always used L10s in ours for work, they seemed to do the job.

I use champion L10’s also, she will run well on them, the only snag is getting hold of a pair. I have also found that champion L86c and NGK B5HS are very similar more modern plugs and they both work well too.
