76 MGB - with Weber DGV with Allison Electrical Ignition
I bought my MGB last November and have been working on it through the
winter. It was drivable when I got it and it is licenced, but has not had
a emmission inspection yet.
I have tried to use it and drive it around for BCW and have seen a few of
our friends, but not as many as I thought I might 3 RBB and a Triumph.
Anyway, this week has seen the longest drives and I am beginning to notice
things that need to be straightened out. The most troubling has been a
loss of power when trying to accelerate. This has been accompanied by the
tachometer acting weirdly. Usually goosing the accelerator has cleared up
the problem, but I still have an occasionaly back-fire.
Today, I tried to look at the distriutor to see about the gap, but I can
find no adjustment in the Allison setup (the externals looks like it should
be the lucas eletronic distributor, but the innards do not match the
manuals and it is connected through a Allison black box). Though on a short
drive last week I did see a midget and a Triumph. I also disconnected the
vacuum advance from the distributor and then took it for a test drive. It
still has some hesitation when the accelerator is stomped, but the real
missing and the backfires are gone as well as the tach works right through
the changes. I realize that the symptons indicate a timing problem, but I
have yet to find the TDC mark on the crank so I have not been able to do
either a static or dynamic timing. ANy suggestions would be appreciated.
On another note, the PO had rebuilt the engine shortly before I bought it.
He did not reconnect the cable to the heater control. Could some one tell
me which way the control works so I can be sure that I can turn it off. I
do not need it on now that the weather has warmed up.
TIA.
