Carb jet setting for high altitude
Posted: Tue Nov 14, 2017 10:25 pm
Hi every one .
Please can some one tell me where to get specs on the sizes of different jets for high altitude? I am at 1500m but do intend traveling at the coast now and then, probably a 50/50 scenario. Southern Africa is my playground
Have seen a choice of the following jets available to purchase for the Zenith 36;
Idle Jet 55 Carburetor Zenith NDIX 36 7001084051-55
Idle Jet 60 Carburetor Zenith NDIX 36 7001084051-60
Main Jet 125 Carburetor Zenith NDIX 36 7001084041-25
Main Jet 135 Carburetor Zenith NDIX 36 7001084041-35
Main Jet 140 Carburetor Zenith NDIX 36 7001084041-40
Idle Air Jet 110 Carburetor Zenith NDIX 36 7001084071-10
Idle Air Jet 130 Carburetor Zenith NDIX 36 7001084071-30
I have also noticed the following concerning my two carbs;
Are both carbs supposed to have the same jets? Because one has Idle Jet 55 and the other Idle Jet 60 , Main Jet 135 the other Main Jet 140 and the choke disks are also different, one is a No.2 and the other a No.6 i.e. one has small holes and the other bog holes (one of each circled in red).
Thanks in advance
