The fuel won't reach the engine so the combustion isn't good, so you get dirty thick smoke and the engine may stop.
It is possible that it is related with altitude too, because on high altitude is less oxygen, so the combustion will be different.

I could be wrong but in reading Black Cross and Red Star the accounts mention the fact that when the Bf109 would be put into a dive the Throttle Command system would enrich the mixture thereby producing trails of smoke out of the stacks. The Russians would think they had gotten kill when in fact they had not. More conjecture, story telling?
Would this happen at max throttle settings, with MW injection, the mixture would be enriched automatically prevent pre-detonation and produce the smoke trail?
