 |
|
The engine ran fine when it was removed from the aircraft. It was
prepared for storage according to Rotax operating instructions about 4
years ago. I can't get it to restart when remounted on an aircraft.
There is fuel in the float bowls. The A and B mag switches ground the
mag circuits at the junction on the engine. The starter provides 250 rpm
and maximum fuel pressure around 5 psi. The throttle is at minimum and
the choke is on maximum.
The carburetor throats are dry after cranking the engine enough to get
50 psi of oil pressure. (The filters were removed)
I would like to verify that the ignition is working before I rebuild the
carburetors. Is there a safe/recommended way (Propeller avoidance) to
verify the spark at the plugs?

Ron, Yes there is. Get an inline ignition spark checker and plug it into a spark plug wire between the wire and the plug. The checker has a nice bright light and is easy to see in all but the brightest mid day sun. Harbor Freight has them (pn 36258) as does Sears, Snap On, Matco, etc. HF sells them for about $3. Snap on for about $20. The rest are some place in between.

Dang, hit the send button while my brain was in neutral. I did my 582 up with misting oil and followed the directions for all the rest. The idle passages in the carbs still plugged up with gelled fuel. Once they were cleaned out the engine started and idled like a champ.

There was no mention that you removed the plugs and cleaned them after storage. Every time I've stored an engine according to manufacturer's instructions, I had to clean the plugs thoroughly to get it started. AND that is all I had to do if it was running fine before storage.

Thanks for the info. I thought there was something like that.
Tom
I pulled a plug and it was Carmel colored and dry. I will clean all the
plugs and see if it works.
Thanks
Ron
