High Altitude Carburetor Kit
Treker vehicles shipped from the factory are stocked with
carburetors designed to operate efficiently between 0
and 4,999 feet. Carburetor change over kits for different
altitudes may be purchased from your nearest Land
Pride Dealer as follows:
Elevation
Carburetor Kit No.
0’-4999’
99201-ZG8-1050
5,000’-7,999’
99201-ZG8-1020
8,000’ & up
99201-ZG8-1000
IMPORTANT: The air-fuel mixture in carburetors
modified for high elevation is too lean when
operating at elevations below 5,000 feet. Operating
engines with modified carburetors below 5,000 feet
can result in engine overheating and serious engine
damage. Return carburetor to original factory
specifications when operating at low elevations.
