Never file point contacts! just use a fine grit emory cloth. plugs fouled?
Hi Art,
old maggies need all the help they can get.
My usual trick is to reduce the plug gap to around 0.012"-0.014" and see what you get.
Got 2 recalcitrant Ponies to fire off this way at a recent Cat Rally here Downunder.
If you still have no joy then you may have moisture in the Mag.
As said above use fine wet/dry paper folded over to clean both closed point faces at once.
Do not pull the paper all the way out or grit will embed in the points faces and cause problems.
Open the points by hand or by rolling the engine over and remove the paper keeping the points open.
Next use a piece of clean non-shiny paper---edge of news paper is good --to then draw thru the closed points to clean off any grit, oil etc. Do the same method as above re the points, and do not pull the paper all the way thru and out or fibres from the paper will stick on the points and insulate them from working.
Have used this method, as taught to me by my Dad who was an old biker from way back in the 30's, and it works.
Hope this helps.
Cheers,
Eddie B
