gq running bad ~ load it missfires

[narns1mav]

hi just havin a problem when i take off from a intersection in 1st gear or say put it into say 5th gear at like 50kms to create a load it missfires / breakes down and slightly jerks

its a gq / mav its doing it on gas its a carby model with extractors and snorkel

any suggestions would be great

thanks

Plugs, points and leads will cause this as well as a bad tune of gas.

If its running too lean it will backfire though the carby

for a gas vehicle with points i recommend converting them to pointless ignition systems like a crane cam. simple, easy and they are optical sensor driven, no hall affect crap that i don't like

what do you think about a


PERTRONIX IGNITOR KIT

this kit works off the six flat lobes on the shaft.

Typically they run lean at high load low rpm, I change the secondary converter spring and retune to rectify it. Also electronic ignition on top of whats been mentioned, quality plugs, leads, cap, rotor.
The Petronix is OK as a points replacement but you can only run a points coil or one with high primary resistance, a HEI coil will burn it out due to the higher current draw. I fit an ICE module and coil raising the output from a potential 30 kV to 65 kV with over twice the burn time. The result is a noticable increase in power and low down torque with improved economy as well.

yeah what sort of thing, this forum is for learning not just fixing your problems. so.............. tell us what prob was it

[narns1mav]

changed plugs and it was fixed 1 plug was not the best looking very strange considering i only changed them about 2000kms ago must have been a dud
