Paslode Nail Gun Spark Advice

[JBASport]

I have had some intermittent firing with my Paslode IM65 Nail Gun. I stripped it down and gave it a good clean & oiling. Before I completely reassembled it , I thought I would check the spark. I noticed that although it sparked on every trigger operation, sometimes the spark arced between the tip and the lug above it, but often the sparked would arc horizontally to the case. Is this normal only I cannot seem to find any detailed information on troubleshooting & sevicing Paslode Nail Guns. Thanks

I would guess that any spark is good, perhaps reassemble and try it out now you have serviced it.

Maybe you can 'train it' a bit by sticking a bit of insulator on the case where you don't want sparking.

 

Try with electrical insulation tape and then use a bit of polycarb sheet if that works? See e.g.

Are these 2 points electrically the same point. Do you have a multimeter? 

If so, is there continuity between the two. 

And if that is true then it almost certainly doesn't matter.
