I changed the engine in my s1 recently because the old one lost all compression. I had a spare s2 block and head which I knew where fine so I gave them a clean up and bolted them in. Obviously with all new seals and gaskets, I also fitted new plugs, leads, cap, and rotor arm.
After a few attempts it fired up, it was running a bit lumpy and idleing at 2k revs, I saw sparks coming off the leads so they were changed but eventually it cut out and wouldnt start. The reason was fuel had stopped leaving the metering head. I changed this for a s2 item and it fired up again but still idled high. So I screwed in the idle screw on the base of the throttle body, had no effect, screwed out the mixture screw to run it lean, still no effect and now I cant turn the thing off!!
Ive checked the timing and it is spot on, checked all the plugs on the inlet manifold and theyre fine, checked for air leaks and all seems fine so Ive run out of ideas now.
Any help and ideas will be greatly appreciated, cheers
Sorry for rambling lol
