I have to agree with Bennie! HAve you check the pick-up line in the tank, it may be getting sucked up against the wall of the tank. Also check the breather on the fuel tank, it may be blocked or too small. These are typical signs of fuel starvation. Please advise the following: Total operating time ...

to Greylingr Before we jump to tearing the engine apart, try using something blunt, you want to be ale to push onthe ring adn ti return with a slight spring action, the movement is less than 1mm. DO NOT DAMAGE the ring in any way, be careful! If there is absolutely no movement, get your tool box out...

First to answer kb's question: I assume you're asking about signs of detonation - 1. While operating in the high range (5800 - 6500 rpm) you may feel a slight flat spot/jerk, this may be accompanied by a spike in the EGT readings if you have gauges to measure this. 2. Melt droplets around the spark ...

With exh manifold removed, you will be able to view the piston walls and rings through the port. Remove one sprak plug on each cylinder to make turning the crankshaft easier. You want to push on the rings to ensure that they are not stuck inthe ring grooves on the piston. Inspect the piston walls fo...

New engines are supplied with these rubbers loose, they are fitted at installation of the engine.

If you suspect that there may be a defect in that particular one, please return it to me for investigation.

Lead has been used in fuel to boost the octane rating and with the phasing out of lead, some fuel companies started using MMT which contains manganese to boost the octane. This was also phased out as it's also a 'heavy metal" and manganese is just so unstable. Almost all unleaded fuel contains alcoh...

Remove the RAVE valves and clean them. The stud between the vlave and the plastic cup should be turned in to it's maximum on both ends. Check the diaphragm and replace if necessary. Remove the cables use to actuate them, they do no work, just leave it alone. One you've done this and you still experi...

Morpheus, Well Done! and I must say that you have installed and wired it very professionally, May I use your wiring diagram for training courses? I'm not a regular "Picasso" I would also like to add that electric pumps must always be installed in series to the standard Rotax fuel pump and NEVER in p...

The most comman cause of failure on these rubber sockets is over-tigtening of the clamps. The clamps should be tightened until you hvae a gap of approx. 7mm between the clamp ends. Although your picture is not very clear it appears to me that the clamp is over-tightened. I have found that these sock...

Before I confirm that you should block off part of your radiator, lets try and determine if the gauge and sender are in fact giving you the correct information. It is very important that a gauge is calibrated to the sender unit being used. Therefore it is important to always purchase the gauge and s...

The cooling circuit on the new 582 mod 99 with the blue cylinder head works very differently to the older engines. The thermostat in the older 582 would restrict the coolant flow when the engine was cold and would start to open at around 60 degC in an attempt to maintain the temperatures between 60 ...

What is the total hous of operation? How often is the aircraft flown? When last were the needles and needle jets replaced? Have you checked for water in your fuel? Carb icing is a reality, but if you are flying with others and you are the only one experiencing problems, very unlikely. Try using AVGA...

The unit has been used in the US on Rotax engines for over two years without any reported problems. It has been mentioned to me by several acquaintances in the US for some time now, but I have been reluctant to release it until Rotax released a Service document about it, send me a message (niren@avi...

the change is not yet finalised, It has been a result of one person asking for this, however, I will look at the list of participants and discuss individually. I will keep you informed.
