Mikuni PHH44 jetting

Recommended Posts

It was suggested that I come here to seek advice for jetting because you all have more experience with Mikuni PHH side draft carbs. I have a PHH 44 S5.

The car isn't a Datsun, but is a '76 California spec MG Midget with a stock 1500cc engine. This carb hasn't been on the car yet.


Currently set up with:

Venturi: 34
Main jet: 150
Main air jet: 200
Pilot jet: 57.5
Pump nozzle: 40

Just one carb. I haven't installed it yet, so no idea on how it runs. I need to replace the exhaust system as well at the same time I install the carb and intake. The exhaust manifold is cracked. Gonna use a Maniflow system from the UK.

The jetting sounds like stock baseline Mikuni jetting.


I'd try it first and see how it runs.


I have a single PHH44 on my 1275 Sprite and it runs great. I could check that jetting and let you know what it is. I've got a built motor though with a huge cam and a giant header. Might be an apples to oranges comparison.
