This is a genuine Tecumseh OEM ignition condenser, part number 30548B (also listed as 30548-B). This condenser is used in breaker-point ignition systems found on many vintage Tecumseh engines.
Unlike aftermarket replacements, this is original Tecumseh factory stock (NOS) designed to provide the correct capacitance and spark control needed for reliable starting and smooth engine operation.
Commonly used on Tecumseh engine families including:
TNT
H70
HS
HH
HM
TVM
and other point-style Tecumseh ignition systems
The condenser works with the breaker points to prevent point arcing and ensure a strong, consistent spark. A failing condenser can cause weak spark, hard starting, misfiring, and burned points.
This part is increasingly hard to find in genuine OEM form, making it the correct choice for restorations and serious small-engine repairs.
