1990 Volvo 240 Question: Can a mechanical distributor be used in lieu of an electronic distributor?
Daughter blew up the original engine and when trying to drop in a used engine, we discovered that the newer engine has an electronic distributor. The old one was mechanical. Since my wiring harness has no extra wires for the electronic distributor, can I swap them out and use my old mechanical distributor? - anglehead
Take out both distributors and compare the way they are "driven" static time the distributor and make sure the advance curve for the ignition is OK and does not cause "pinging/detonation" best to use components designed for the original engine. Recheck that the cam belt timing marks are OK then get number one cylinder up on compression and static time the engine so spark arrives a few degrees before TDC. Alldata won't cover the basics of static timing the engine but is great for all other information. Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online - patrick mannion
