shizzl Posted December 8, 2008 Share Posted December 8, 2008 what would cause a engine to start backfiring through the carby? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted December 8, 2008 Share Posted December 8, 2008 bad ignition timing normally or the wrong firing order Quote Link to comment Share on other sites More sharing options...
mikuni Posted December 8, 2008 Share Posted December 8, 2008 have you just slammed a new carb on or has it just started doing it randomly? sometimes new carbs take a while to equalise or what ever you would call it. if its existing setup check timing Quote Link to comment Share on other sites More sharing options...
Jase Posted December 8, 2008 Share Posted December 8, 2008 missing half an inlet valve?, generally timing dude, but if you've stuck a valve open or mashed one it could come back through the inlet, is it your stockie? Quote Link to comment Share on other sites More sharing options...

KKtrips Posted December 8, 2008 Share Posted December 8, 2008 check for condensation inside the distributor cap.. dry it out and also spray a tonne of 5.56 over the sparkplugs and HT leads Quote Link to comment Share on other sites More sharing options...
MACKAZ Posted December 8, 2008 Share Posted December 8, 2008 Check your rotor boe. Common fault with falcs in stockcars. Its prolly spun the tab off. Stockcar fact no3 Always always always have 3 spare rotors in tool box if you run a 3.9 or a 4.0.....only takes one good hit and bam fuckzord Quote Link to comment Share on other sites More sharing options...
shizzl Posted December 8, 2008 Author Share Posted December 8, 2008 does the rotor actually touch the little knobby things in the cap? also is the rotor supposed to be "winged" tip?my one seems to sit about 3mm from the little knobby bits... no.6 plug was wet,all others were bone dry... i dont know now ae..dizzy is definately spinning too. fuel pump is working fine. power to the coil..

MACKAZ Posted December 8, 2008 Share Posted December 8, 2008 pull the rotor out of the dizzy and look at the locating tab, can almost guarantee thats what it is bro......I know its a cunt getting the cap off but, just fucking do it ok.......dizzy will spin, but the rotor wont be pointing where its meant to be.
