Product details
PMO part PM-O136-3 is a size 130 idle air jet for PMO Induction carburetors, the replaceable air bleed that tunes the idle and low-speed circuit on these Porsche 911 carburetors. EMPI, which now builds the PMO line, lists the 130 as the stock idle air jet size in every PMO carburetor. Owners usually buy it to replace a jet damaged or lost during cleaning, to undo an earlier tuning change, or to keep spares. Fitting the 130 returns that circuit to PMO's factory calibration.
PMO carburetors carry two kinds of air jet, and the names get mixed up. The main-circuit air correctors are IDF-type jets in EMPI's 43-5410-0 to 43-5421-0 range. This idle air jet, sometimes called the idle air corrector, affects only the low-speed circuit, and PMO also offers it in 90, 100, and 110 sizes. Note where each jet came from before cleaning a set of PMOs.
Technical Details

Fitment & Compatibility
Fits all PMO Induction carburetors, sold in 40mm, 46mm, and 50mm sets for Porsche 911 engines from 2.0 to 3.6 liters. It does not replace the main air corrector in a PMO, Weber IDF, IDA, or DCOE carburetor.
Installation & Tuning Notes
A change here alters idle and transition mixture, so recheck the mixture screws and carburetor balance afterward. A larger idle air jet leans that circuit and a smaller one richens it.
Common Questions
I lost one idle air jet while cleaning my PMOs. Is this the right replacement?
If the carburetors were at stock calibration, yes. EMPI lists 130 as the stock size in all PMO carburetors.
Can I use this as a main air corrector?
No. It belongs in the idle circuit.
