Hi Everyone I have a 1982 camper based on a 2l Transporter with electronic ignition. Haynes manual and another source states ignition timing to be 4 - 6 degrees ATDC with the two plugs from the idle stabilisation unit joined together and vacuum pipe connected. When I set the timing to this spec using a strobe light it is quite obvious that the ignition is retarded to the extent of backfiring. Anyone have any ideas - is this the right spec? Also if i advance the ignition until the vehicle appears to be running properly idle speed is too high even after adjustment at carburettor. (I started fiddling in the first place because of bad hesitation under pressure - could this all be connected?) Any suggestions very welcome please. TIA Brian
