Outer Limits 4x4 Board

my dual fuel gq shorty has bein playing up lately. first the tacho starts to drop slightly then it drops and bachfires. all the conections have been cleaned and its still doing it.
any ideas?

It is your points. Put a new set in and problem will be gone instantly (for about 10000kms until it needs another set)

Change the condensor as well as points. Get a genuine condensor about $25.00.
