AIPICO Points and Condenser Kit for Onan B-Series Engines (BG/B43/B48) — Restores Ignition, Improves Starting & Idle

AIPICO's 160-1183 / 312-0246 points and condenser kit restores reliable ignition timing for Onan B-series twin-cylinder lawn mower engines.

If your Onan B-series engine (models BG, B43E/G/M or B48G/M) is misfiring, hard to start, or running unevenly, worn ignition points and a degraded condenser are often the cause. This aftermarket kit from AIPICO supplies replacement contact points and a condenser engineered to match the factory fit and function for many Onan twin-cylinder engines. It’s a straightforward repair that can bring back crisp ignition, smoother idling and more predictable starting behavior without replacing the whole magneto assembly.

How will replacing the points and condenser improve starting and idling?

Old points can develop pitting and improper gap, and condensers can weaken, both of which disrupt spark quality. Installing fresh components restores precise contact timing and consistent spark energy, improving cold starts and steady idle.

• Renewed contact surfaces for stable spark generation
• Correct condenser capacitance to prevent misfires
• Reduced hesitation during throttle changes
• Better engine response right after cranking

Will this kit fit my Onan BG or B43/B48 engine?

The kit is designed for Onan twin-cylinder B-series engines, including BG, B43E, B43G, B43M, B48G and B48M. Verify part numbers and engine family before ordering to confirm compatibility with your specific model and production year.

• Compatible with Onan BG and listed B43/B48 variants
• Aftermarket replacement matching OEM mounting points
• Fits engines commonly found in commercial and residential mowers
• Check engine paperwork or existing part numbers to be sure

What should I expect during installation?

Installation typically requires basic hand tools and some mechanical familiarity. The job involves removing the magneto cover, swapping the old points and condenser for the new parts, and setting the points gap per Onan specification for correct timing.

• Simple screwdriver and wrench work for removal/installation
• Gap adjustment and timing check recommended after fitment
• Replacement usually takes under an hour for experienced DIYers
• Refer to engine manual or a service guide for exact specs

Are these parts durable and worth choosing over a full magneto rebuild?

AIPICO manufactures these components for long service life and reliable performance, making them a cost-effective alternative to replacing the entire magneto assembly if the armature and coil are in good condition. They provide a targeted fix when ignition problems stem from wear in the points and condenser alone.

• Aftermarket quality aiming for longevity and consistent operation
• Ideal when only points/condensor show wear or failure
• Lower cost and quicker turnaround than full magneto replacement
• Good option for routine maintenance or restorative repairs

Who this is for: This AIPICO points and condenser set is intended for lawn care professionals, equipment technicians and DIY enthusiasts who maintain Onan B-series twin-cylinder engines. It’s a practical purchase if you need a dependable replacement for worn ignition contacts and capacitor without investing in a full ignition overhaul—especially when you want fast delivery and parts matched for common Onan BG, B43 and B48 models.
