    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.
