 Posted: Mon Jul 06, 2009 5:59 am Post subject: Idling problem... |
 |
|
Flew yesterday.. Everything normal on the taxi out, run up, and throughout the flight..
Landed after 30 mins, throttled back to idle... and the engine wanted to stop!
Had to taxi with a fair amount of power to keep the engine running.
Back at the hanger throttled back to Idle.. and she quit!
Any ideas as to what might cause such a sudden change??? Water??
Thanks in advance

M14P or Huosai??????
Sounds like a fairly large intake manifold leak.

Check to make sure your primer was/is locked in the closed position.

M-14, and the primer was locked... first thing I checked.
I had a water in fuel problem a few hours ago... wondering if there might be some residual?? Vladimir and I thoroughly drained the tanks and the fuel filter... Might try that again today.

Some thoughts:
Yes, check for more water.
Is this known good fuel?
Take a look at fuel pressure at idle.
Pull both fuel filters and check them.
Run on one mag at a time at idle and make sure it does the same thing on
both mags, running on one at a time.
Check intake tubes to be sure they are tight at both ends.
If you get desperate, and nothing else seems to help, and you are using
automotive spark plugs, consider replacing them, and make sure they are
gapped correctly.
Find a good mechanic. I am not one of those. Vladimir is one of the
best. Tell him I said hello.

Thanks Mark... I chatted with Vladimir.. he advised the same... There was about 20ccs of H2O in the main filter, and a little in the fine filter!.
She now runs like a dream. We think the water came from a faulty seal on one of the tip tanks.
Thanks for the advice.
