Out of the blue my vitesse 1600 lost power and stopped. Had one start with full choker on hot engine. Very high revs and a supecious synthetic smell. Ignition okay, compression okay, fuel okay. Have to had it towed to my garage. It was raining and dusk had settled on. Suspected the diaghrams and when I lifted the top of the carbs the front one was jamed. I.e, I had to use a soft hammer to get i loose and had to use substantial force to pull it of. The piston and needle was jamed. I replaced the piston, centralized and all, and have the piston to run alright. Enhine wont start, no fuel through front carb - at least three dry front plugs , compared to vissible wet three rear plugs. I checked both floath and replaced the needle valves. I blew air through visible holes, cleaned up and reassembled and fitted. Still no fuel to the front three cylinders - dessert dry plugs. When I blew air into tthe carb it pull up fuel fron the float chamber al right, meaning no cludging here. How can the carb get in a state like this? Fire? How come there's no fuel passing through the carb? Will a sufficient big leak in the inlet manifold take all suction power out of the carb?(I did saw some unusual smokw when the engine was running for a few seconds full choked and with very high revs.) Any comments most welcome.

I was just perusing Triumph's owner's handbook for my 13/60 whilst trying to get the hang of the ignition timing process – sorry, I've only had the car since early August, and stuff like this is still a bit foggy for me. Anyway, I turned a page and noticed that the diagrams for the carburettor include a 'coil spring' between the top cover and the diaphragm/air valve (Fig. 95, p. 56, item 15 in the owner's handbook, if you have a copy). I'm guessing the diagrams are generic for the CD150, in that the carb was used for different applications, so maybe some had this coil spring and some didn't. Point is, mine doesn't. Should it? While I'm here, none of the manuals seem to mention the 'spring-loaded pin' that lurks below the top of the carb, that can be used to check the mixture: am I right in thinking this only wants a light touch when in use, rather than being pushed up as far as it'll go? The same diagrams seem to show that its head actually pushes against the air valve when it's lifted. TIA
