Check and installation of ignition are carried out by a stroboscope.

On a wreath of a pulley there are adjusting risks caused at an interval of 5 °. The first risk is located in 20 ° to VMT, and the last – in 5 ° after VMT. Risk, the corresponding VMT, is noted by yellow paint. The arrow noted the index on a forward cover. |
Check and installation
| PERFORMANCE ORDER |
| 1. Warm up the engine, check idling turns, switch off ignition. |
| Carburetor engines |
| 2. Disconnect a hose from the vacuum regulator (or a pressure sensor hose on engines with converter), muffle a hose. |
| 3. Connect a stroboscope according to the instruction of the manufacturer. |
| 4. Start the engine and direct light to a crankshaft pulley. Idling the lit tag has to be opposite to the index. |
| 5. In need of adjustment release bolts of the distributor and turn the distributor case before combination of a tag with the index. |
| 6. Tighten bolts and again check installation of ignition. |
| 7. Check operation of the centrifugal regulator for what be convinced that at increase in turns of the engine the scale on a wreath of a pulley is as if displaced concerning the index "forward", and at decrease in turns to idling the lit tag has to be opposite to the index again. |
| 8. Attach hoses and be convinced that ignition became earlier and the corner of an advancing meets standard. |
| 9. Otherwise the vacuum regulator is faulty (or the pressure pressure sensor) or there is a leak in a hose. |
| 10. Stop the engine and disconnect a stroboscope. |
| Injector engines |
| 11. Disconnect the socket from the gate sensor. |
| 12. Check and adjust ignition (see subitem 3-5). |
| 13. Stop the engine and disconnect a stroboscope. |
| 14. Attach the socket to the sensor of a butterfly valve. |
