If you have all your vacuum retard connected your time should be 4 ATDC, not
10 BTDC. If the vacuum retard is disabled then 10 is about right.

Subject: TR6 Misfire (here we go again!)
Hey All,
OK, I took the TR6 out last night to get ready for an inspection. Let me
remind everyone that I have just finished a rebuild on the engine, and all
other mechanical parts on the car. The car has about 10-15 miles on it
since the rebuild.
I put new Champion spark plugs (Y12NC?) in, gapped at .025 in. Car has a
slight misfire at idle, but that is not what is worrying me. When I try to
accellarate the engine mis-fires badly. I had driven it once since the
rebuild with BOSCH plugs in it gapped at about .045in, and I don't recall
this problem. Once I have the car going at about 20-30 MPH, if I let up on
the gas the mis-fire isn't as bad. Hoiwever I can't see the car being able
to do more than 40MPH the way it is right now!
I checked the points and they are gapped at .015in. Timing is set at 10
degrees BTDC
I'm going to puy the Bosch plugs back in and see what if this is a new
problem or just something I didn't notice the first time I drove it.
If anyone has any suggestions on what to look for please foward them. And
yes I haven't adjusted the carbs on it since the rebuild, no balance and
there needle adjust is set at half a turn from full lean, so if it is not
the plugs this is were I will start.
Later,
JHD IV
