Some times it is quite violent. Almost as if the prop stops immediately when the key is turned off. Idle RPM is set at 1800. I turn off 1 mag prior to shut down to achieve approximately 1650RPM. Any comments/suggestions??

Ferg You need to apply a constant pressure supply to the top of the tank which will force the oil through the system to the pump. It relies on this header pressure to push oil through the cooler and onwards to the pump. The pump will not suck this oil supply until it has adequate oil without "Breaks" in the oil circuit . Once the oil circuit has been flushed of all air bubbles you can only remove the tank or filter once you have clamped the out going pipe from tank to cooler . Neville Eyre does this all with a bike pump and a non return valve.

I don't think he meant he was turning the prop without a filter. At least I hope not. He pre-filled it at the beginning and let it soak through the element. I think that is all he meant by saying "don't put it on". He just meant right at that moment. Fergus let us know. -------- Roger Lee Tucson, Az.

Making sure the carbs are synced at idle. Then sometimes it is normal due to a couple of things you have no control over and like you siad is intermittent. -------- Roger Lee Tucson, Az.

The entire procedure I attempted to follow is: 1. Drain engine/tank. 2. Fill filter half full, don't put on 3. Put 3 litres in tank 4. Turn prop till oil comes out of oil ilter base boss 5. Install filter 6. verify oil pressure by propping or motoring engine without ignition before putting back in service Kevin - I am filling for the first time - obviously wrongly. I will watch the ROAN video you suggest - thanks Roger - I seem to be out of it when it comes to routine. As above, I DID turn the prop with the oil filter off, and so have probably got air into the system. So as you say I have just earned the opportunity to do an Oil Purge. I'll get on that now. Now I see there's a new filter.... SO much to learn, so little time. Graham - I think you're right and thanks for the attention. Bob - You are in agreement with the consensus and so I will do as above what Roger suggests, once I have purged the air. Your explanation has made me understand the system and the routine. I'm fascinated to see how Neville uses the bicycle pump. Thanks.

If you do #4 you are locked into an oil purge. #4 is a bad idea. -------- Roger Lee Tucson, Az. Light Sport Repairman - Maintenance Rated Rotax Repair Center - Heavy Maint.
