Comments Primer engine manufactured by this firm, designed exclusively for racing. It became a favorite choice in pattern flying. Provides the beginning of the pressurization of the fuel tank and a flow regulator to supply a large diameter carburetor. Steel jacket, with deflector piston and ring, on two bearings and crankshaft carburetor with flow regulator. Rear exhaust can be fitted with manifold pipe and tuned exhaust.Because of the delicate membrane after run oil cannot be used with this engine without serious damage.
This engine has a higher compression ratio than most model engines and consequently is very hard on glow plugs under hard running it will finish a plug in a couple of flights. I have even witnessed something that I have never seen in all my 50 years running model engines. I have landed an XLT pattern plane on at least two occasions dead-stick with the engine and propeller turning over. Once where the plug was completely missing and another occasion where the center was blown completely out leaving an open hole.

  1. Hi there I have one of these engines, have got a new glow plug and fresh fuel but still having trouble starting it. Any recommendations?

    1. Based on my experience this engine easy to start when properly adjusted. Possibly your engine is either getting too much fuel or not enough. This condition can be corrected by making small adjustments to the fuel pump setting screw found under the crankcase. Another possible cause could be deterioration of fuel pump seals. This can happen by using after-run oil which is a no-no with this type of engine. The only cure is to replace the seals with new ones. I know this because it happened to me, I purchased a used engine that wouldn't start, from a hobby shop that treated it with after-run.

  2. Where can I get a manual for these engines. I have an older version that has an additional (third) port nib at the base of the carb, but on the opposite side from the fuel/pressure lines.
