back fireing out of carbs

(1/1)

bobtail 2 6:
help needed ive got a 3.5 v8 on su carbs which runs fine at low revs but when you rev it it starts to back fire and fart out of the carbs

Range Rover Blues:
Check the timing then do a compression test.  A V8 will happily idle on 6 cylinders or with numberous faults that only show up under load.

dod51e:
Check the mixture as it may be running too lean.

bogie:
If it was running fine before its most likely electrical.Check each lead on 2 the plugs.Could b knackered plug,lead,points ,condensor (if u have them) modual on elecy dizzy.

solihull-mick:
hi mate make sure theres oil in the dash pots on top of the carbs as this can cause over fueling and popping back :wink:
