check that your air cleaner is clean

i put new gas and a new air cleaner ??

Carburetor is gummed up with varnish from old gas. Need to disassemble carb, soak metal parts in carb cleaner, blow out dry, and reassemble.

Because of blockage and restriction, you are running lean and choke lever is compensating.

Post the Briggs Model, Type, and Serial Number then myself or someone else can tell you specifically which carb you have, and what steps need to be taken.

Can someone tell me what carb I need and where to get one for my giant-vac leaf blower.

Serial: J-500478
Model: 170402
Type: 2015-01
Code: 83053110

Thanks in advance for your help.
