I've just replaced the timing belt which broke whilst on the M5.
All is back together Idles great the best it's been, but wont go over 30 kms (45 downhill).
It's a 90 model 2 litre Econovan
Can anybody tell me what the timing should be and whether the air/fuel mixture screw allows more fuel in or restricts it when wound out.
The valves are fine, the belt looks to be in the correct position with everything at TDC.
Plugs and leeds are good.

If anyone thinks they might know another problem i'm open to all options.

Cheers
Steve.

I have done the timing belt on my dad's econovan before, but i just cant remember those details lol. I suggest you find yourself a similar year Telstar/626 manual as they shared the same engine. this should tell you those details. are the points alright?

Didn't leave a rag in the air intake??? Don't laugh I've seen it done by very experienced techs.

sound to me as if you didnt line the timing marks up

once you set the belt up did you wind the motor over twice to see if the marks lined up again

sounds to me if it were running fine before that u might have the cam timing out a tooth or two. it happens, it's just a pity that it's a van and a prick of a job. hope this pic helps. i've left it big deliberately just in case u wanna print it out. if it's the wrong setup let me know what engine it has. i just went on 2.0L 90 econovan. another really quick way to tell if the cam timing is out is poke a timing light at it. if the cam is out then the distributor and igntion timing will be out also as the dist is driven off the cam.

Thanks guys,

No rag in the intake, all marks are lined up (just checked it), and the timing is set at 8 deg BTDC but i'm not sure where it is sposed to be.
think i may have to for out for a manual.

ok i tracked down some information for you. this is from my dad's econovan owners manual.

Ignition timing at idle: 6 +- 1 BTDC
Spark plug gap: 0.8mm+-0.05mm
Breaker point gap: 0.50+-0.05mm
Distributer Dwell angle: 52 +-3
