Thanks Roland and Jim, Since Jim brought up fuel and ethanol, I should =
add that I only use Shell 91 which has zero ethanol. Ethanol will =
marginally reduce gas mileage. Also, I run my tyres with 30lbs of =
pressure.
=20
I did a Google search on fuel consumption in Healeys and it seemed that =
it should be around 18-20 mpg (imperial), however a poster from Germany =
reported getting about 10.5 in the first 1000 miles after rebuild but =
after a few thousand miles and more carb tuning he about doubled it. =
Maybe I ought to be patient. I have been driving it gently, certainly =
for the first 500 miles. Perhaps I need to thrash it a bit! Mike =
=E2=80=93 do I have you permission?
=20
When I was 20 and had just bought it I could fill the tank with Esso =
Extra at the station where I worked for under $7 (cdn). I filled up =
yesterday with still a quarter of a tank left and it cost me $97+. Damn =
scary.
=20
I=E2=80=99m looking forward to more comments =E2=80=93 I still think it =
10.1 is exceptionally low, even taking into account the rebuild.

I would suggest that you put another 1000 miles on the car and then do =

Hi listers, As you might recall, I just had the engine rebuilt on my =
BT7 last year. I only have 670 miles on it so far. My fuel consumption =
seems exceptionally high. I have just checked on one fill up, and need =
to repeat to be more certain, but on the last tank I got an awful 10.1 =
miles to the Imperial Gallon (14.8 miles/US gal). I used to get about =
double that.
I have checked the tune on the carbs using the usual method and checked =
it with a quick plug check (I have yet to do a proper plug chop), and =
if anything I think I am running a bit on the lean side. The exhaust =
seems good, just rich when the choke is on, however the engine does =
=E2=80=9Chunt=E2=80=9D a little when at idle. It runs beautifully =
otherwise. No fuel leaks at all.
=20
My questions: 1) what are others getting for fuel consumption? And 2) =
any thoughts on how to improve it?
=20
Thank all - Mirek
