If you need to block off the Oil Metering injection bungs in the rotor housings, such as when running premix with the gasoline, these plugs are the answer. While they are hard to find Metric plugs, they screw in hold securely, without causing damage to the threads. We have been using them successfully for many, many years.

DO NOT install on any vehicle lacking a means to lubricate the combustion chambers and associated seals. You must be using premix in the gasoline or running some alternate metering oil lubrication for the chambers & seals.

We recommend using Red Loctite to secure the plugs in the housings to prevent seepage.

Price is for a PAIR.
