TR6 Misfire (here we go again!)

[John Duhart <duhart@symbol.com>]

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
