Post by: chaz on 05 Apr, 2020, 18:58
looking for a couple of sizes for the A10 Dyno and mag screws
E3L dyno , the screw that holds the  200902 cover on, mne is too long and not holding tight
and
the countersunk screws that hold the round alloy cover on the magneto one missing

those threads are normally 2 BA . if the threads strip you could try a metric tap and m5 or m6 screws

thanks Eddie
the cap looks like 2BA but the two countersunk look smaller.
will have a closer look and nip up the unit to get some gauges.  8)
