Where can I order poulan 2150LE parts at California?

Rick, easiest just to order a coil by using make and model # of the chain saw.
MA 15 does show up a replacement Walbro coil.
Check the attached links,instruction and guides, Good luck

Use and impact wrench. It will turn fast enough to turn the nut.

Because the cat that is approved for California is "finer tuned" than the other 49 states. California emission standards are the toughest in the country, so many engine and emission parts are made just for those standards.

Order part no. 128774. My poulan mower takes the same mandrel as your.

146527 is the part number, you can order it from mowerpartsweb.com

You can use this site to find a Poulan service center or order parts:
http://www.poulan.com/

American Yard Products (AYP) is the manufacturer and the part number is: 142829 the part the part description shows sub= 145775.

A few days ago i would have you here:

They have locked the site to non dealers. Please go here:

To register your displeasure. They should be willing to help you with their product.
It used to be fairly simple to find parts. This new system will hurt their sales IMO. Tell them that! HTH

Your model is a 2150LE. There is a Type 1 and 2. The linked IPL is a 2150LE Gas Saw Type 1. Click the "View the illustrated parts list [Go] button here:

What little detail there is is on the "Handle, Chassis, & Bar" drawing.
A blunted, hooked piece of wire can be used to pull the hose in the oil tank out. I recommend the filter be replaced. Work your way through the linkage cleaning and replacing any defective parts as you go. The oil pump (52) is often behind the clutch. The saw can be operated without the bar and chain to verify oiler operation. GL

Have you tried to order direct from Poulan at Poulanpro.com if not they have a toll free number that you can call to get in contact with one of their dealers and that should get you up and running again.
