First time starting the engine after rebuild

Post  RobBFG on Fri Oct 29, 2010 8:56 pm

I tried starting the Elf's engine today. It seems willing but isn't firing.

I haven't put the air cleaner box on yet. When I tried starting it the first time I got a puff of grey smoke from the inlet of the right carb, and the second and third were from the left carb.

I'm guessing it's a timing issue, but I've never had to deal with that before. Where do I go from here?

Re check the static timing and the distributor cap wiring. The static timing must be on the Compression Stroke of the #1 cylinder. Both valves on that cylinder should be closed during compression.

IT'S ALIVE!

I'm a bit scared though. When I put it all back together I set the distributor where it was when I took it apart thinking "If that's not right, it'll be not far wrong". I've just turned the distributor about 30 degrees anti-clockwise to get it set right. The vacuum advance was pointing to the coil above the alternator before, it's almost vertical now. I can't help thinking that something went back wrong somewhere now. The distributor drive shaft in the engine is set at the correct angle according to Haynes and I didn't dismantle the distributor itself.

Screw haynes's instructions. I'd just move the distributor drive to a better position for timing, that's what I did on mine and it ran like a good one. Very Happy

Despite what's said about Haynes at times, the information on this subject from them does match my 1961 Mini and 1969 Elf / Hornet BMC workshop manuals. I thought I'd check just in case.

Regardless of how the distributor drive was installed the static timing routine will get the timing set. It is just the orientation of the distributor that will be affected. Re set the drive so that the distributor is oriented the way you want it, regardless of the manual.

I believe the rotor arm should be in line with number one plug. That is a straight line through centre of the R/arm to the plug using a ruler. Hope this helps?

As BMCELF has said, setting the timing has nothing to do with where the vacuum advance or rotor are pointing. The rotor could be pointing anywhere just so the cap and wires are set to match. The timing all starts with where the distirbutor drive is set. It is nice, however, to set it up as the workshop manuals suggest!
