Those old Quadra are a very good engine although very heavy for the power out. It is almost impossible to wear one out. You do need to have the carb serviced, most lawn mower shops have the repair kits for about $10 and they are easy to install. Just pay very close attention to the disassembly so that you can do the reverse when you put them back together, maybe the lawn mower shop will do it for you. You will find the number of the carb stamped on the carb itself . they like to start wet, choke the devil out of them before flipping the prop. I've always started mine with the spring starter but the 24 volt helper would be appreciated. I've never used the electronic ignition (all mine are the old fashioned type) but those I've seen with electronic ignition are sure easier to start, well worth the conversion if you can afford one.
