My TR6 ran well. I parked it in the garage. 2 weeks later it would not start. After alot of monkeying around I measured the fuel level in the jets, both were 1 plus inches, much too low for fuel delivery. More monkeying, I found the fuel pump pressure less than 1/2 psi. Rebuilt the pump, now it's 2 1/4 psi(right in spec.) The fuel level in jets went to approx. 1/2" now, still too low. I measured the float levels, they were 17mm, I reset the floats to 16mm. The fuel level in the jets is now about 3/8". It runs OK now but both needles are set to full enrichment. I can not understand what happened, why the fuel level dropped just sitting in the garage for 2 weeks.
BTW: the math. conversion mm to inches in the Triumph shop manual and Haynes manual is incorrect. The authors flunked 3rd grade arithmetic.
