I bought this older model and would like to know if it is 4 stroke engine that uses gas rather than mixed gas. There is no model or serial number. The air filter needs to be changed but I don't know where to buy it from. Thanks for your assistance.

DO NOT mix oil in the gas on your four stroke engine. You will foul the spark plug(s), build up deposits on the valves and head, and make a smokey, smelly mess. A two stroke engine uses the fuel/oil mix to lubricate the engine before being used as fuel. A four stroke engine has a separate lubrication system and does not normally burn any oil. As the name implies, a two stroke engine works in two strokes. The first stroke is downward, where the fuel/oil mix and air are drawn into the cylinder. The momentum from the crankshaft counterbalance or force from the other cylinder(s) drive the piston back up compressing the mix, and the spark plug sparks at or slightly before the top of the stroke. The rapid combustion of the fuel/oil/air mix drives the piston down, which is the power stroke, and then the cycle starts all over again. A four stroke engine has an intake stroke down taking in the fuel/air mix, a compression stroke up, a power stroke down as the fuel/air mix is ignited at or before the top of the stroke, and a exhaust stroke up before starting all over again. A four stroke is much cleaner and more reliable than a two stroke, but it is heavier and has less torque. A two stroke engine is much lighter and has more torque, but takes more maintenance.
SOURCE: What mix of oil and gas do i use?
I have that exact same saw. The mix you need to use is 40:1. That is 40 parts gas to 1 part oil. I have tried finding a handbook for mine and have had no luck at all. Not much out there for McCulloch saws. I will try again to find one for you though. It is a very good saw! I have had very good luck with it with not many problems. One problem I did have though, is that they put really cheap fuel lines in them that will crack on you after a couple of years. It's an easy fix, but it will leave you baffled on what is wrong with it.

Remove the Carb Bowl and on the bottom of the bowl clean the center of crust gas....
It blocks the gas from getting from the bowl to the inside of the carb.
Caused when gas dry's up in the bowl leaving deposits behind plugging up the works.

A 4 stroke motor does NOT have Oil in the Fuel. There is NO fuel mixture. Just use regular gas. The only place you need oil is in the sump, and regular 20/30 motor oil will be fine.This only needs to be replaced when low on dipstick in crankcase.
