Yeah but also has the standard B20A map. I am using the B18B, like it better than the Amazon cars map.

I did confirm that the hose was connected to the correct nipple with the restriction orifice. Also add that I have a new break booster, NRV and hose. My 123 distributor is the preset type from Skandix. I confirmed the correct setting for B20A. The car drives okay, easily cruses at 55mph anything over that the wind noise is unbearable and its returing 26-27mpg(UK). Rough idle maybe something I have to live with. |

Check your oil filler cap and the gasket. It should be airtight.

How have you set the idle mixture? Did it idle nice after you rebuilt the carb and reinstalled it? Did you replace the seal and bushes on the butterfly throttle shaft? What oil have you got in the dash pot?
My 71 B20A specs are 21 to 23 deg at 1500rpm for ignition. My isolation plate between the carb and manifold was cracked and my spare was also cracked. It idled nicer after it was replaced. It should idle lovely. I think they will always fluctuate a little with the Stromberg with the carb piston but nothing too much.

It appears that 10 deg timing is for B20B, and 21-23 deg is for the B20A.

I also found a service bulletin 20-16 issued in '74 for timing adjustments for the different octane ratings of the day. There is some interesting documents on this webpage with the help of google translate from Swedish. http://www.240.se/litteratur/sm20-16.pdf http://www.240.se/ Last edited by bdhurley; Aug 2nd, 2021 at 17:45. |
