Reg's Air-cooled Engines March 1991 Service Bulletin

Time again for the start or continuation of a new flying season. So be prepared and give your engine a COMPLETE check up. There is a lot YOU can do reduce the chance of an engine failure.

One WORD OF ADVICE  (I know I keep harping on this) but a possible 60-70% of engine failures can be attributed to fuel related problems. Some of these include, STALE FUEL MIX, remember once oil is added to gasoline it tends to reduce its pump octane and hasten its degeneration. I hope the following will be of help.

STALE. FUEL; If left in the tank for more than a month, GET RID OF IT. Any sign of water or dirt remove the tank and clean it OR BE SURE ITS CLEAN. Why  take a chance on old or contaminated fuel mix. 

To clean your tank a suggested method would be to go to a automotive car wash where they have a power washer with a soap solution and clean the inside of the tank, then wash it out with clean water without the soap solution) and let dry thoroughly.

CHECK FUEL LINES; for tightness at ALL CONNECTIONS, especially on the intake side from tank to fuel pump). Remember it is easier to draw air than it is to draw fuel. Reg's Air cooled Engines stocks a good quality fuel line so if your in the market for fuel line give us a call. 

Always use a good quality inline fuel filter. BEWARE of some of the automotive gasoline filters, they are as they say gasoline filters not oil filters. and some types of two stroke oil can start the filter element to break up and plug the fuel system. 

Also some of the screw on bowl type can cause a problem especially if you drop the seal on the ground and don't see it or forget to tighten it. Remember always try to reduce the chance of potential problem. KEEP IT SIMPLE. 

Always use a fine mesh screen funnel when filling your tank from an outside source e.g.; jerry can or barrel). MAKE SURE you use the correct pump octane fuel for your particular engine. 

Its listed in you engine owners manual and if you don't have one get one, there cheap and full of good sound information. We stock these if you need one. If you are not sure of the octane requirements give us a call and we'll try to help you out.

ALWAYS USE A 3O-I RATIO MIXING OIL in the 185's; also make sure it is for high performance - severe service operation. Don't go cheap on oil it could cost you a lot more than the little extra you pay for good quality oil. NUFF SAID.

We have tested Castrol Super Two Stroke and it appears to be quite satisfactory. Be very careful of synthetic oil, some of these tend to draw water. The plus factor of these oil however are that they are very consistent. We have yet to be convinced they give longer life and better fuel consumption than a good quality petroleum base two stroke oil. 

However if your not sure on the type of oil to use give us a call. One more suggestion on fuel, BEWARE OF ADDITIVES, some claims are really wild. Reg's Air Cooled Engines or Rotax dose not recommend them. Snake oil and magic elixir may be okay for the body however I have not seen much proof as to its usefulness in a Two-Stroke Engine under U/L conditions. SO BEWARE.
