When using the single-vacuum distributor, the vacuum hose runs from the vacuum port on the left side of the carburetor to the vacuum canister on the distributor. In that case, the vacuum port on the rear of the carburetor must be plugged.
For most cool season grasses and for folks living in northern climates, the best time to plant grass is in late August, early September. Depending on exactly the climate you have and the type of grass seed you're planting.
Plantings of warm season annual grasses can be made in the spring as soon as the soil temperature (at a two-inch depth) warms to 65Âº F and can be planted as late as July without a yield penalty (Table 3). Seed can be broadcast or drilled in narrow (more than 15 inches) or wide (up to 36 inches) rows.
