We are really glad you are asking for hel= p, and I suspect someone who understands this motor may give you a hand,&nb= sp; but we really want to keep you around.  

 

Please be careful.   I know tha= t you have to figure out what is wrong, but perhaps there is a way to do th= is that doesn=E2=80=99t put you in excess danger?

Subject: [LML] Engine "sur= ge" issue

 

Whenever my GAMI injected IO360 powered L= ancair 360 is really heated up, following a flight and only a short time to= cool down (less than 30 minutes) and restarted, the engine will surge duri= ng idle and taxi.  Again this only happens when the engine is hot, has= been shut down and restarted.  The issue never occurs when the airpla= ne (engine) is started for the first time on any given day (super hot day o= r super cold day).

 

Since I feel the issue is fuel related I = tried leaning and use of the electronic fuel pump during idle and taxi with= zero improvement.  The engine runs very badly with a pronounced surge= .  If I get on the runway and give the engine full throttle, the engin= e will develop good power and lift off as if there were no issue...that is = until yesterday when the engine just about quit 2000' into my takeoff roll.=  I aborted the takeoff, did some high speed taxiing and then took off= 3 minutes later (no shutdown).

 

Today I took off, climbed aggressively to= get the engine good and hot and landed.  I shutdown, let the engine s= it for about 10 minutes, restarted and once again experienced the surge dur= ing idle and or taxiing.  I removed the upper and lower cowl but am st= ill not able to identify the cause of my issue.

 

Clearly I have an issue that is caused by= heat affecting fuel.  All of my fuel lines are heat shielded.  C= an anyone offer suggestions or ideas that I can try?
