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.
Usually planted in the early fall, cool-season grass seeds prefer daytime temperatures ranging from 60 to 75 F. With this temperature range, the soil itself is usually between 50 and 65 F -- the right environment for germination.f your seeds remain at their ideal temperature range and are planted no more than 1/4 inch deep, you should see germination after three weeks. It is critical to keep the top 1/2 inch of soil moist with a misty spray so the seeds continue to absorb moisture as the seedling grows larger.
