Düsenflugzeug Haupt #85 NON O.E. ALTERNATIVE

Main jet 85 for Keihin-type carburetors used on Honda’s small four-stroke engines. It meters the main fuel flow and has a direct effect on mixture strength at higher throttle openings. Many older Cubs, Scoopy scooters and ATC engines show signs of wear or blockage in this jet, often from long storage or poor-quality fuel. Fitting a fresh 85 restores clean running and steady throttle pick-up.

Made to the same thread and orifice pattern as the original, it drops straight into the stock carb body with no adjustment needed. Commonly used across C70, C90, SH50 Scoopy, CH80 Elite, ATC110 and NH-series engines. A small part, but vital when bringing an old Honda back to life.
