Hey Guys,
First let me say that I went to check my plane over tonight after
last nights engine stoppage. I found nothing of concern so I took it out
and it started right up. I warmed up and ran normally. I still believe
that it was vapor lock and subsequent flooding trying to restart that was
the problem. I don't believe carb ice or the lack of using carb heat. I
had given it a little goose on short finial and it responded quick and
strong, no sign of trouble not more than 10 seconds before it quit. The
only thing that I did change tonight was idle was a little low at 650 to
680 rpm. 750 is where it was supposed to be. My fuel lines in the cowl
are all fire sleeved but the gascolator is unprotected. I am just about
finished making a box and blast tube for it and it will be installed
before she flies again. Really after thinking about it some more it may
have just stalled from low idle and hot air in the cowl making her go
lean. For the record I may be stupid , but I do have carb heat and
believe I know how and when to use it. I am trying to share all my
experiences to save some one trouble I may have had. Fro the most part
this discussion has been good and beneficial.
For my parting bit of wisdom for tonight "When I tell newer guys
at work not to do something I let them know it is because I already tried
it and have the scare some where to prove it"
Thanks for the help
