A tuning note on this: If you choose to run straight manifold vacuum to your vacuum advance in order to gain the additional timing advance at idle, you must select a vacuum advance control unit that pulls in all of the advance at a vacuum level 2â below (numerically less than) the manifold vacuum present at idle.
To avoid these diseases plant only healthy cloves, manage weeds in the garden, and take care not to injure garlic bulbs while working in the garden. Plant garlic in an area where no onions, chives, leeks, shallots or garlic have been planted for the past 4 years.
Purchase bulbs from mail order suppliers, garden center, or other local source. Break bulbs apart at planting time, keeping papery husks on the individual cloves. Plant with tips up, 2 inches deep and 4 to 6 inches apart in rows 15 to 24 inches apart. Plant elephant garlic varieties about 3 inches deep and 8 to 12 inches apart. Mulch heavily after planting to prevent soil heaving - particularly with less-hardy elephant garlic varieties.
