"Three cyclinder volvo penta,

"Three cyclinder volvo penta, The battery is OK when start is pressed the engine turns for a long time. Compression is good. Eventually it fires off with plumes of white smoke 1200 rpm. It will wind up to 2200 rpm - still smoking. Return to idle - engage prop and open throttle under load. Smoke disapears and engine runs quite normally when warmed up. Can any one help me find the start up problem please?"

I would check the fuel injecto

I would check the fuel injectors- it sounds like at least one of them is sticking open until the motor runs for awhile. Remove them and have them checked at a shop. The white smoke is unburned fuel.
 
"I have same problem 3 year ol

"I have same problem 3 year old MD2030D, thick white smoke on starting improves with warm up. Noisey uneven tick over. Since new it has blown 3 sets of glow plugs and has needed injectors servicing. Checked timing of injector pump and it seems to be fuel cut-off at 16 degress - some 4 to 5 degrees late. Why? What could have changed. Can anybody help please?"
