I only realised when I rejetted my DGMS.
Are the jets definitely size 45 because when I took the jets out of my new
carb the idles were 50s and mains were 135s?
The carb was supposed to have 142 mains and 45 idles.
would be better checking all the jets, the emulsion tubes and the air correctors ..
idle jets 45, main jets 142 (145 up to 1976) air correctors 185, tubes F50.
your original DGAS will (should) have been set-up properly, so investigate that, then if the parts are different then order correct sizes for your new carb .. I suggest a known weber dealer, not just any eBay gamble .. http://www.fastroadcars.co.uk/store/index.phphttp://www.webcon.co.uk/
hope that is of help to you
