ignition timing wtf
Car - JDM ae86
motor -AE92 100kw smallport
use - daily atm
problem - ignition timing out, misfiring
occurs/started when - when i changed the dizzy o-ring
well i changed my dizzy o-ring and now i cant get the fucker back in time... i was so careful to mark everything but i turned it over and it misfires like a bitch. i have bridge T and E1 and set TDC 0" (crank and cam gears all line up) and the dizzy accordingly but i cant seem to find a happy medium, it is either too advanced or too retarded.
so any ideas? anyone in brisbane done this before? really could use a fresh set of eyes and thoughts.
the crank timing is as follows: 20 15 10 5 0 5. if its right of 0 it misfires and splutters and left it won't rev past 5000rpm.
You are supposed to set it at 10. Read the manual.
i understand that and have set it at 10 BTDC but i am still having problems. i used this as a reference:
You are using a timing light right?
lol yes... i know it seems odd to still have a problem after following everything properly but i just can't work out what is going on.
You're in the same boat as me then. We set ignition timing to 10 with check connector bridged. Car was so slow as all hell so we set it to what we thought felt about right which showed up as like 25 on the gun unbridged.
You have original crank pulley? I got some aftermarket thing. We suspect that's the reason it's being so goofball.
Yeah I'm pretty sure mine is original, and it is doing the same as yours, 20-25 unbridged. It's really starting to do my head in to be honest...
maybe you have put 2 leads on teh wrong way round or something like that......
it would explain the missfire and not revving
also a good thought, but they are on the exact way they came off. this does raise the question though, should the number one lead plug onto the dizzy where the number 1 is embossed?
i would pull the dizzy out and start again.. if u are even a tooth out where the dizzy gear meets the exhaust cam your screwed.
u should also notice - looking at the cam gears they should line up with the 2 markings on the rear cam covers. - 1 dot on each gear and risen line on the rear cover above each cam gear.
then re check the crank... and also check the valve position on cyl # 1 - all 4 valves should be closed
if all from the above diagram is good and what ive mentioned above is good.... the stuff i have no idea...
