Congratulations on getting the engine running well. Now, good luck with the Electrical stuff. Boy, I hate electrons. Regards, Tim Engel ...   05-20-2024 01:54 am

The baseline question is, "What do you want the engine to be?" Asking others what they want or like doesn't answer that question. ...   05-03-2024 01:17 am

5325 P, and 5326A ?? If so, then those carbs were originally for the Sunbeam-Talbot Lotus rally cars... the 'street' homologation version. The engine ...   03-11-2023 04:56 am

I wasn't objecting to Dellortos... I much prefer Dellortos over Webers or Strombergs. There are several variations on the 'DHLA 45' theme, designated by a alpha ...   03-01-2022 08:59 pm
