Yes, the taper section is visibly longer. (Estimate 0.5mm.) Inspected both under magnifying light thinking that shorter one may have tampered with but appears to be original. There are at least 3 versions of the PHF/PHM mixture screw, 2 of which you can find on Bevels - see the picture below, with ...

As suggested i then swapped carbs front to rear. Still backfiring on front cylinder. Good! That's progress, Mark :) You probably know this already, BUT DON'T DISTURB the pick-ups unless you absolutely have to. If you do, they will need to be re-positioned using a special tool, and even then it's no...

Oh, and maybe this will help.

If your choke piston looks like this, change it.

Further thoughts: 1. The idle on a PHF depends on a clean air feed as shown below. Idle air passage.jpg Now, as you can see, that drilling narrows within the carb body. As you can imagine, it can easily get partially blocked at this point - and stay so, even after an ultra-sonic clean. So be very fu...

Initial quick thoughts/questions: 1. Have you checked for air leaks around the intake manifold, both where it bolts to the head - did you fit a new gasket? - and where the carb clamps on? (Don't over tighten the clamp). Hold the engine at a low idle and get someone to spray something inflammable lik...

Hi Brad, Yeah, they can be a little difficult - me too, SSD owner. The oil change is a good 'first idea'. You should be running a synthetic 10-50 anyways - or at least that's what Ducati told you to do :-D (ref. last page of the owner's handbook). The only problem you may encounter is a little clutc...

I was stripping more paint on the frame today and found a faintly stamped 350GT in front of the frame number. Interesting! I have found no reference in any of the published sources to this "350GT" frame stamp*. However, I see there are 2 registrations (ref. 1025 & 1031) of bikes with it on the Beve...

Good one, Eldert - thanks!

As Bob: not a Mach 1. Both engine and frame are wide-case. But interesting because ... The homologation number (IGM 1985 OM) is the old narrow case, 250 'Type B' code, that was first issued in November 1964. When the wide cases came in (late 1967- early 1968), this code was initially carried over, u...

Hi Julien and welcome to the Forum, An interesting challenge :) . Frankly, IMO, given where you are in the world, you cannot do better than to ask advice from Steve Allen, the owner of this Forum. With his experience and knowledge of all the people he has dealt with over the years, I feel he will be...

I didn't think it likely that the float valves would have aged and hardened. You could be right; but every spring I have to replace float valves in Dell'Orto carbs, float valves that have stopped sealing in less than 4 months of inactivity. And judging from reports on other forums, I'm far from bei...

What should I do next? Thanks. Very, very simple. Buy a new float valve from Steve ... https://store.bevelheaven.com/Dellorto/Float-Needle-Valve-250/ ... and install as per the instructions above. A wise man would do this with both carbs. You might also consider buying one of Steve's float height g...

I think you can sleep ok. The Goldline range never had any covers in the first place, and I haven't heard of anyone having had problems (and I haven't had any either ... )

Ok, let's start by going back to basics :) . Why do carburetor manufacturers install accelerator pumps? Pumps are fitted to provide the temporary shot of additional fuel that is required under rapid acceleration. Without pumps, the engine may starve and falter. This Wikipedia description is pretty g...
