Just being able to order the parts from one place and know that they were the correct items for the generator saved a lot of time and aggravation trying to find them at automotive parts stores. I would have liked it if they provided the 5 qts of oil also. The biggest problem is how to pour the oil into the filler cap with only about 3 inches of clearance. I solved that by using a 2 ft length of 1 1/4 in copper pipe with an elbow at each end - one facing down and the other up; putting a funnel in and pouring the whole 5 qt container in in about 3 minutes. It could also be done by buying 5 1 qt containers and laying them sideways.
