[@saisubhranshumohapatra9795]

Which size 170 or 190 for the 376/215 carburettor kindly help me to purchase

[@MyRestoration1]

Hello my friend. My bike in built and in storage but I found the original service manual and it clearly says the main jet size for the Redditch made 59’ 350 Bullet is 190 (with air filter) needle jet 106 needle position 3. Pilot jet 30. Hope that helps!

@@MyRestoration1 thanks my friend 😊😊

[@daveco1270]

So that bike doesn't have a heat insulator block between the carb and the manifold?

[@MyRestoration1]

Not that I’ve ever seen?

Good video. I have a 376 - 25 on a Bultaco. Cleaned and all new jets and cable but slow to return to idle after revving. The float, slide and choke are original. Any ideas? Thanks

[@MyRestoration1]

Hi. It’s a simple carb so not much else to look at as you describe it then the last part of the cable return. One of the errors I see is not having enough slack on the throttle before you engage revs. The tendency is to set the tension of the cable so that there is no play. It’s a natural tendency because we like a tidy bike! There must be as much as a quarter turn of nothing before the cable engages. Why? Because when you rev up and drop off the cable must be absolutely free at that last bit of the drop because the spring is so slack any tension will cause this slow drop in revs. If it’s not that then you could have a sticking point to find. Basically the needle is not closing off to stop flow back to the idle jet. There isn’t much else to look for I can’t think. Good luck 🤞

Was that Time Out in the background? Great video!

[@MyRestoration1]

Spotted! Indeed. Mr Brubeck!

[@daveco1270]

the monobloc is a lovely looking carb but it seems like a flawed design with the opening of the bowl on the side. When I bought my 1964 Triumph TR6 the monobloc had been replaced with an Amal Concentric carb, which works great. I still have the original monobloc, but it's sitting on a shelf as a display piece for now. I wouldn't mind putting it on the bike at some point to see if she runs any different with the original carb.

I found a lot of negative stuff written about these carbs. If you set them up right they are solid and dependable. Very little to go wrong. If seated correctly with a new gasket, as I show in the video, then no problems. On occasion the pilot jet might cause the engine to die after a rev up. Not sure you can fix that other than raise the idle a bit. Someone will surely comment. 🙏
