Thank you. Engine runs cool and timing and carburetor mixture are spot on. That leaves carbon as the likely culprit tho I may try cooler plugs as well …<br><br><br><div class="yahoo-signature"><a style="font-size:12px" href="https://apps.apple.com/us/app/aol-news-email-weather-video/id646100661">Sent from the all new AOL app for iOS</a><br></div><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: rgb(132, 115, 255); padding-top: 15px; margin-top: 0px;">On Monday, September 2, 2024, 8:25 PM, Michael Oritt <michael.oritt@gmail.com> wrote:</p><blockquote class="iosymail"><div id="yiv0857949366"><div><div dir="ltr"><div style="color:#3333ff;" class="yiv0857949366gmail_default">Running on may be the result of several different factors including incorrect timing, carbon in the combustion chamber and high engine temperature.</div></div><br clear="none"><div class="yiv0857949366gmail_quote"><div id="yiv0857949366yqt84453" class="yiv0857949366yqt8389481143"><div dir="ltr" class="yiv0857949366gmail_attr">On Mon, Sep 2, 2024 at 4:34 PM Robert Markovich via Healeys <<a rel="nofollow noopener noreferrer" shape="rect" ymailto="mailto:healeys@autox.team.net" target="_blank" href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br clear="none"></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex;" class="yiv0857949366gmail_quote"><div>
Wonder whether today’s ethanol fuel contributes to the run-on (dieseling) many Healey owners experience. If you’re lucky (and have set carbs and timing correctly), you can solve the problem by flooring the gas pedal after turning off the ignition and inundate the cylinders with air, especially on a BJ8 with its larger HD8 SUs. Otherwise, as on my BN7, you must stall the engine by lifting the clutch pedal in fourth to keep it from running on. Am trying Techron combustion chamber/fuel system cleaner on the chance removing built up deposits will do the trick, but we will see …<br clear="none"><br clear="none"><br clear="none"><div><a rel="nofollow noopener noreferrer" shape="rect" style="font-size:12px;" target="_blank" href="https://apps.apple.com/us/app/aol-news-email-weather-video/id646100661">Sent from the all new AOL app for iOS</a><br clear="none"></div><br clear="none"><p style="font-size: 15px; color: rgb(123, 106, 246); padding-top: 15px; margin-top: 0px;">On Monday, September 2, 2024, 1:01 PM, Bob Spidell via Healeys <<a rel="nofollow noopener noreferrer" shape="rect" ymailto="mailto:healeys@autox.team.net" target="_blank" href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:</p><blockquote><div id="yiv0857949366m_6777466826901163723yiv8790107236"><div>
Living in California, I have been running 'gasahol' in all my cars
longer than some. Best we can usually get is 91-octane; I was able
to buy higher-octane--93 and 100--fuel at times but, guess what: the
octane was boosted with ethanol (added water to some and measured
before and after; don't recall the exact mix but IIRC I figured it
was 10% ethanol; standard from the pump seems to be about 8%).<br clear="none">
<br clear="none">
I have about 140K miles on my BJ8 running mostly 91-octane gasahol,
and there have been no negative effects save some 'vapor lock*' on
starting when hot. I replaced the hard line to carburettor flex line
that had been on the car for a couple decades and, except for it
being a little stiff there was no visible degradation. About 8 years
ago I put a new carb jet in pure/denatured ethanol and there is also
no visible degradation. Rubber components sold since the
introduction of gasahol are impervious to the stuff. Theoretically,
due to its oxygen content gasahol could cause an engine to run a
little lean, and at least one knowledgeable person recommends
changing to rich carb needles, but both my cars have long since been
tuned to run on it with std. needles. The BJ8 was rebuilt to
standard 9.1:1 compression ratio, the BN2 is a 100M and has the
'high compression' 8.7:1 pistons. I've been told Healeys will run
fine on 91 up to about 11:1 compression, depending on the cam and
timing. <br clear="none">

Good luck trying to 'steal' from an airport--when I owned airplanes
I would occasionally get some--but the fuel providers aren't likely
to be enthusiastic about selling it to you. Technically, you would
owe 'road tax,' and the stuff is full of TEL and highly toxic (don't
breathe any of it and don't let it get on your skin). <br clear="none">

* not technically 'vapor lock,' but the alcohol vaporizes and
cavitates the fuel next to the exhaust manifold, causing some
stumbling for a mile or so.<br clear="none">

A message from Canada. For the last 30 years I have been running
my 100/6 on 93 gas with no alcohol.

<div>Other than stealing gas from an airport any recommendations
