RE: Blowing plugs after every flight 56LX engine
I'll try to help.
I went through this with a SJ60LX.
1.Check ground rpm and fatten it up, drop it down about 800 rpm from peak. It is better to error on the rich side.
2. If this does not solve the problem. Remove it from the plane and set it up on a test stand. Adjust as neccessary. You could have fuel foaming in the air so dial it in on the ground and get it running right. Then if after flying if you pop plugs you are too lean (sucking air,foaming).
Jett engines turn high rpms and they need fuel to be there so leaning them out just over heats them and pops plugs. Remember when they are flying through the air the engine becomes unloaded at some point and rpm go up higher than ground rpms.
Hope this helps
