This has me baffled.


I changed the timing belts and the cam indicators were set correctly before and after installation (12'oclock on the valve cover seam, one rotation of the crank and then 12 o'clock on the other) with the center valve timing hash mark. I tried setting the ignition timing to 0 and #1 TDC and then installing the distributor with it pointing at the brake booster. No start. Set it at 8 deg, no start, The only way it will start is to set the timing on the flexplate attachment bolt  beyond the 20 degree mark. It starts and runs pretty well (especially once warmed up).


What gives??


1985 GL EA81 1.8 SOHC,Carb, Auto (for now) and AC.

You've got me baffled as well.  How did you change timing belts on an ea81?  Did AZ ea81s come with timing belts?  Pictures please.  Sounds more like you've got an ea82.

Sounds like you have an EA82... I haven't rebuilt one of those but I'd put money on a simple thing you missed.  Do you have a manual you're working from?  If not I would recommend picking one up they're cheap and the and the answers are in there.

You set the rpm at about 800 rpm and disconnect the vacuum line to the distributor.

I've followed all the instructions in the How to Keep Your Subaru Alive and the Haynes manual and the Miles Fox videos, and a number of years of previous Subaru experience,  but if I time it per the instructions it won't begin to fire off. Time it beyond the marks and it runs very well and had lots of power and re-starts well. Cold starting is troublesome but I think that is a choke related issue. Every critical pulley has a pin or key to ensure it can only go one way, so I don't see how I could have gotten them out of time, and I never removed the cams from their carriers, so I don't think I got left and right cams mixed up.

Sounds like you have the distributor installed one gear tooth off.

I've tried installing it at the proper position and moving it 1 tooth ahead (advanced) but the ignition is still too retarded there. I am setting it about 30 degrees ahead in  order for it to start and run smoothly. I thought the plug wires were all off by 1 position, but that's not the case either.

try to feel for an 'in-between' gear on the dist. Mind you that the rotor will rotate some as the gear engages the crank
