success starting & floored accelerator

[Mercedes Fred]

after a bout of cold and a frosty engine, i got the car to start once the battery got recharged, although i had to actually put the accelerator to the floor and hold it there, as the engine would not catch as well while turning with foot off accelerator...perhaps flooring it either i) solves a flooded engine (lean) or ii) enriches the gas/air mixture or iii) something is seriously wrong with my 88 300e

comment?
