Guaranteed Carburetors….Established in 1980

Guaranteed Carburetors, the premier provider of automotive and marine carburetors has roots dating back to 1976 in a small shop in Old Bridge, New Jersey. 

Our founder, Bob Hartzell worked alongside his dad before opening his own location in Largo, Florida in 1980 and quickly earned a reputation as an expert carburetor rebuilder and specialist.

Through the years, a highly skilled team was established and today, we can proudly say that our team have worked together for many years and in some cases, decades.  In that tradition we are dedicated to serving our valued customers with the same exceptional quality and service first established way back in 1976 in that little shop in New Jersey.

Guaranteed Carburetors provides:

  • Large stock of OEM and Aftermarket Rebuilt Carburetors
  • All carburetors are carefully disassembled, cleaned and re-manufactured to industry best quality assurance standards, for over 40 years
  • Thoroughly tested and adjusted for your application to allow for years of smooth operation
