How will this carburetor kit affect engine starting and idle?

Replacing a worn or clogged carburetor and its associated filters often restores crisp cold starts and steady idle speeds. Fresh internal passages, a new fuel pump and a clean air filter improve fuel mixture consistency and reduce stumbling or stalling at low RPM.

• New diaphragms and jets for steady fuel metering
• Included fuel pump ensures consistent fuel pressure
• Air and fuel filters prevent contaminants from disrupting idle
• Gaskets and clamps secure leak-free installation
