McCulloch PRO MAC 700 MODEL 600116-06 chainsaw Parts

For the Mcculloch PRO MAC 700 (model 600116-06), the engine size is typically about 70 cc. On Sears PartsDirect, this model is listed under model number PRO, so we use the saw’s full model name (PRO MAC 700) when matching specs and parts.

How to confirm you have the PRO MAC 700 variant

Because “PRO” is a shortened model identifier on the parts listing, confirm the exact saw version using the ID tag and basic features before ordering parts.

• Check the model/serial tag on the saw body (often near the starter housing or handle area)
• Look for “PRO MAC 700” and the full identifier 600116-06
• Confirm the bar and chain size currently installed (pitch and gauge)
• Note whether it is hard to start, runs rough, or leaks fuel (these symptoms guide which parts to inspect)

Why cc matters when troubleshooting and buying parts

Engine displacement (cc) helps you match the correct fuel system and ignition components, and it also sets expectations for power and safe cutting technique.

What you’re doing	Why the cc helps	What to check next
Tuning or rebuilding fuel system	Carb settings and fuel delivery must match engine demand	Air filter, fuel filter, carburetor condition
Diagnosing hard starting	Larger engines are sensitive to stale fuel and weak spark	Spark plug, ignition, fuel lines
Choosing cutting approach	Higher cc supports longer bars but needs PROper chain speed and sharpness	Chain sharpness, bar oiling, chain tension

Quick checks if your PRO MAC 700 is running poorly

• Drain old fuel and refill with fresh, PROperly mixed fuel
• Inspect fuel lines for cracks or softness
• Clean/replace the air filter
• Check spark plug condition and gap
• Verify the chain is sharp and PROperly tensioned

Yes. Mcculloch chainsaws are generally a solid choice for homeowners and PROperty maintenance because they are built for practical cutting performance, manageable handling, and dependable durability when they are maintained correctly. For your Mcculloch PRO chainsaw, overall “good” comes down to condition, tune, and using the right chain and fuel mix.

What “good” means for a chainsaw

A chainsaw is doing its job well when it starts reliably, cuts straight, and stays cool and lubricated under load. We look for these signs:

• Starts within a few pulls when cold and restarts easily when warm
• Idles without the chain moving (PROper clutch and carburetor tune)
• Accelerates cleanly without bogging (fuel delivery and air filter condition)
• Cuts without pulling to one side (sharp chain, even cutters, correct bar condition)
• Oils the bar and chain consistently (oiler and oil passages clear)

Quick comparison: what to expect

What you care about	What you should expect from a well-running Mcculloch	What usually causes complaints
Starting	Predictable cold starts	Old fuel, dirty carburetor, weak spark plug
Cutting speed	Strong cutting with a sharp chain	Dull chain, wrong chain type, low RPM
Smooth operation	Stable idle and clean throttle response	Air leaks, clogged fuel filter/lines
Longevity	Long service life with routine maintenance	Running lean, poor lubrication, dirty air filter

Why it matters

A “good” chainsaw is not just about power. PROper chain sharpness, correct fuel, and reliable lubrication reduce kickback risk, prevent premature engine wear, and help your Mcculloch PRO deliver consistent performance season after season.

If yours is hard to start or runs rough

These are the most common, high-impact fixes on gas chainsaws:

• Drain old fuel and refill with fresh, PROperly mixed fuel
• Check the spark plug condition and gap; replace if fouled
• Clean or replace the air filter
• Inspect fuel lines for cracks and the fuel filter for restriction
• Verify the chain brake is fully released before starting

Your Mcculloch chainsaw (model PRO) usually cuts out because the engine is getting too little fuel or too much air, especially when you squeeze the throttle. The most common causes are stale fuel, a restricted fuel filter or fuel line, a dirty carburetor, or a plugged spark arrestor.

Quick checks that fix most cut-out PROblems

• Drain old fuel and refill with fresh, PROperly mixed fuel (if your saw is 2-cycle).
• Inspect the fuel cap vent; a blocked vent can create vacuum in the tank and starve fuel.
• Check the fuel filter and fuel line in the tank for clogging, cracking, or loose connections.
• Clean or replace the air filter; a heavily loaded filter can make the saw run rich and bog.
• Inspect the spark plug; replace it if fouled, wet, or the electrode is worn.

Step-by-step troubleshooting order (fastest to slowest)

1. Fuel quality first: If fuel is older than about 30 days, replace it.
2. Fuel delivery: Pull the in-tank filter and inspect the fuel line for soft spots or splits.
3. Air and exhaust: Clean the air filter; then check the muffler spark arrestor screen for carbon buildup.
4. Carburetor: If it starts but dies on acceleration, the carburetor may need cleaning or rebuilding.

What the symptom often means

When it cuts out	Most likely cause	What to do next
Idles OK, dies when revved	Fuel restriction or carburetor issue	Check filter/lines; then service carburetor
Dies after 30 to 60 seconds	Fuel cap venting PROblem	Loosen cap briefly to test; clean/replace vent
Bogging, smoky, won’t rev	Air filter plugged or mixture too rich	Clean filter; check choke operation
Loses power hot	Plug, coil, or exhaust restriction	Check plug gap/condition; inspect spark arrestor

Why it matters

Running lean from a fuel restriction can overheat the engine and score the cylinder; fixing fuel delivery and carburetion early helps PROtect the piston and crankshaft seals.

For the Mcculloch PRO MAC 700 MODEL 600116-06 chainsaw, use a 40:1 gas-to-2-cycle-oil mix. That equals 3.2 fl oz of 2-stroke oil per 1 U.S. gallon of gasoline. Mix only what you will use soon so the fuel stays fresh.

Quick mix chart (40:1)

Use this chart to measure accurately and PROtect the engine.

Gasoline amount	2-cycle oil at 40:1	Metric equivalent
1 U.S. gallon	3.2 fl oz	95 ml
1/2 gallon	1.6 fl oz	47 ml
1 U.S. quart	0.8 fl oz	24 ml
1 liter	0.85 fl oz	25 ml

How we recommend mixing fuel

A correct 40:1 mix lubricates the piston, rings, crank bearings, and cylinder so the saw runs cooler and lasts longer.

• Start with a clean, approved fuel can.
• Add about half the gasoline.
• Measure and add the 2-cycle oil.
• Add the remaining gasoline; cap and shake well.
• Label the can “40:1” and date it.

If the saw runs rough or will not start

Fuel mix is only one piece of performance. If it still acts up, focus on common fuel and carburetor issues.

• Drain old fuel and refill with fresh 40:1 mix.
• Check the spark plug for fouling; replace if needed.
• Clean or replace the air filter.
• Inspect fuel lines and the fuel filter for cracks or restrictions.
• If it bogs or surges, service the carburetor.

For step-by-step help, use tips for a hard to start chainsaw and chainsaw runs rough.

Why it matters

Running 50:1 in a saw that needs 40:1 reduces lubrication and can score the cylinder. Running too rich (too much oil) can foul the plug and reduce power.
