MG TD TF 1500 - MK II Carbs
|Decided the other day it was time to install those carbs I rebuilt last summer.... We got them installed but just couldn't get them running right....(seemed to be running on 2 cylinders and doing a lot of popping)... nothing we did seemed to help, so off they came...old ones on and ran smoothly again. Am going to replace the needles and do a thorough check for air leaks.... certainly looked good however.....
|Are you sure each carb is getting fuel? Are they Balanced? Is the mixture nut backed down the same number of flats on each carb?|
|Yep...we did it all, and matched them as per specs.... we don't think however that the right needles are in them....they were running so lean we couldn't get enough turns to richen them up....still mulling over the problem...|
|I suspect this isn' t the answer, but worth a thought anyway!|
The MkII has a direct feed to each of the carbs from each of the two pumps, and a balance pipe between. Is is it possible that, with a higher air/fual throughput rate, the radiator end carb is not getting enough fuel? More likely to be a problem at higher revs, but ... .
|I don't think that's a likely culprit, Ian, as I have seen Mark II cars run with a single fuel pump for years, with no discernable difference in poerformance. The second pump seems to have been intended to ensure sufficient fuel during sustained high-speed runs.|
