The lawn mower uses to much gas. The air filter gets dirty.

Recently when I was mowing I noticed the gear shift to low and saw a plastic bag wrapped around the drive shaft and blade. After removing the debris and adding a new spark plug the problem remains.

Can I Use 5W-30 Instead Of SAE 30? Both oils have a “30” hot viscosity rating. This means SAE 5W-30 oil has the same flow rate as SAE 30 at operating temp. So, technically it`s fine to use SAE 5W-30 oil in place of SAE 30.

One of the biggest advantages of using 10W30 oils is that they can sometimes be used in place of SAE 30. While it is not recommended, doing so will not cause damage to the engine. This is due to the multi-grade oil properties that make this particular oil flexible enough to use in various temperature conditions.
Yes. 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature.

I have a Poulan 550 158cc Push Mower. Two Model #’s 96132004200 and PR0550N21RH3. Two Serial #’s 0901075421770 and 011309M001762. The mower will run if primed then dies. The carb. is on the tank. I took the tank and carb. off and blew through all openings. Air was coming out all the openings. Still no fix. Can someone please help?
ANSWER : Does it have fresh gas in it, If so time to rebuild the carb, even though you blew through all holes there is a diaphram inside the carb that pumps gas to it, so I suggest you take the carb apart and clean inside out and replace the diaphram, the way you describe it only runs on primer, tells me the carb is not getting fuel. Good Luck
