The Saga Continues - Primer
Posted: Fri Feb 17, 2012 11:15 pm
Well, I checked out my carb and didn't find any
problems. Put it all back together and did some ground
run-ups, and everything worked good again.
I then took my primer off to have a look. The two O
rings on the plunger seemed fine. When I looked into
the tube, though, I saw some crap at the back bottom,
what almost looked like the remnants of a gasket. So my
first question to ask, is there supposed to be a gasket
at the back that the plunger backs onto to seal the
end? I cleaned it out, but couldn't tell if it was just
plain dirt or not. Or maybe this was just a collection
point for dirt, that would then work itself into the
little hole where the male ball end goes into and not
sealing like it is supposed to, and thus allowing fuel
to get sucked by into the cylinders.
The primer brand is Essex Engine Primer.

Thanks to everyone again for all your advice. I still
have a few things to check and will be working on it
again tonight. I've got my carb off now, so
will have a
good look at the float and valve there, even though I
really don't expect a problem with it. My best guess
currently is the primer as Wayne describes, primarily
because it matched the symptoms when I applied primer
in flight. However, I don't like changing too many
things at once without testing it, so may not get to
the primer right away.
Wayne, below you asked what altitude. It has now
happened at any altitude from just above sea level to
5000.
I will let you guys know what I find next. Thanks.

Walter start with the easy one, since you
are running rubber eating car gas,
and pull your primer assembly apart and
check the O-rings, or at least
borrow a vacuum pump ($60 item at CTC) from
a car mechanic and start sucking
on the outlet line to see if this is a
possiblity before disassembling.
Something has changed quickly on you and I
suspect your primer inards may be
kaput.
