Sthil BG55 blower - carb?

This blower will run low but not with throttle. Gas is comming out the backside of carb. Too rich and I can't seem to solve it by the adjustement screws. Any suggestions would be most appreciated.

Thanks in advance,

Lance

If the carburetor is flooding it could be caused by a bad needle/seat, sticking fulcrum assembly, or bad stiff diaphragm. In any case the carburetor needs to be disassembled for inspection and most likely will need a repair kit installed as well a through cleaning.

Check the muffler for blockage. Some mufflers have a screen, others have a stub (tube) with screen and BG 55 Series 4229 has a catalytic converter. Each of these can become clogged with carbon creating blockage restricting exhaust flow resulting in the symptoms you describe. Clean as required and only use Stihl 50:1 oil mix.

Other than the muffler you may have a carburetor issue.

I think your blower has a Zama C1Q carburetor. Here are some helpful links if it is carburetor related.
