I went to check the ignition timing on my 82 Gl wagon(EA-81). I hook up the timing light and then open the Haynes manual...

paraphrasing... "Look at the sticker under the hood for the correct timing figures"

Some bastige has repainted my car at some point and very thoughtfully removed any signs of a sticker under the hood on my car. Hence I have no idea what degrees from TDC +/- I might need and at what revs/idlespeed this needs to be.

Right now the car is dieseling, running quite hot, backfiring, refusing to idle at a reasonably low RPM, and just generally seeming to be telling me it's out of whack in the iginition dept. If my guesstimates are wrong I'm more than happy to hear anyone elses. I just thought the timing was a good place to start

What idle speed and timing setting do I need ??

cheers in anticipation ! :)

My sons 84 Brat with EA-81 engine is 8 deg. BTDC. Idle speed I think was 600-700

I will have too look at the other stuff when I get a chance. I hope this will give you some info at least....

went out and adjusted it and yes... huge difference. I haven't had it that long and it seems that someone negelected to tighten the dizzy adjustment bolt, or its worked itself loose in the last few weeks, which would make sense, because it got steadily worse.

for the record I had 10 deg ATDC.... suffice to say that probably fixed all the ills previously mentioned, though I'm still looking for more reasons just in case. I've had too much experience with cars that have been 'fixed' by shadetree mechanics in the past.... the things people do to cars ! :)
