Do not use Slick-Fifty or other oil additives in a Rotary Engine.

Spark Plugs

Use only NGK or Nippon Denso brand plugs.

Oil Metering Pump

All Rotary Engines have one. It's located on the front right hand side of the engine. It constantly pumps a small amount of oil into the intake manifold to lubricate the rotors and rotor housings. This pump must be working properly. The two hoses that run from the pump to the intake manifold must be in good condition.

Break-In Period

Rebuilt rotary engines have a break-in period of about 150 miles. Rotary engines have many internal seals that are made of metal (Apex, side and corner seals). It takes about 150 miles for these seals to wear in or seat. Fine tuning to the timing or the intake should be done after the break-in period.

Smoking

During the rebuilding process, oil is used to lubricate the engine parts as they are being assembled. This oil along with oil left behind from your old engine can cause some smoke during initial startup. This should stop completely after the first 10 minutes of running.

Warning!

Do not remove the 19mm main pulley bolt from your rebuilt rotary engine. This may result in damage to the needle bearings and/or oil leakage.
