[QUOTE="Gerry Jenkinson, post: 5106, member: 432"] I am replacing the very worn original Carburettor on my '52 Comet with a new Monobloc. I would like to use the new 229 but the Monobloc is affordable. Concentric is cheaper still but I am used to monoblocs as the D has them and parts are interchangeable. I have heard the monobloc is a tight fit under the tank. Question is what jets. Riders Handbook and Richardson say Main 200 Slide 29/3 KTB on "D" Monoblocs "Pilot Standard was 30, but 20 or 25 may give better tickover." "Main can usually be increased to 270 from 250" FYO 1950 Comet with Monobloc. R Swannick Main 280 Pilot 30 Needle 106 He reports better acceleration and 75 miles to the gallon I have also heard an increase of the main to 210 is recomended, all advice welcome Gerry Jenks [/QUOTE]
