Re: which carb?

NH350 Carburetters 1946-54.jpg This is the carb spec for a 276AZ/IJ. You don't need to get a 276AZ/IJ as such, just a 276 with a 1" bore and a 15deg float chamber. The correct jets are relatively easy to get and it's not a bad plan to fit new needle/needle jet anyway as they are often worn out...

Re: Solex AHD26 carb jets

I wonder how hard it would be to make one... Luckily the un-numbered jet in my spares box was a tad under 1.5mm so I have enlarged it to 1.5. The air jets have parallel holes so they ream out nicely unlike petrol jets which appear to have sharp bevelled edges. Does anybody know where I can get gask...

Re: Solex AHD26 carb jets

Many thanks everyone for the comments. Simon's photo of the jet appears to have a 150 stamped on it confirming Paul's information. Now all that I need is to locate one.

All the best, Pete

Solex AHD26 carb jets

I've got hold of an old AHD26 with the correct body and I am looking to re-jet for use on a SQ4. AHD26a.jpg Does anybody know what the jet (circled in picture) does? It seems to be part of the pilot jet feed but the jet list for the SQ4 doesn't mention it. It's marked as 84 on the parts diagram but,...

Re: GB Gearbox

The SQ4 GB pushrod length should be 10-1/4" according to my records.

Did you fit the ball bearing at the clutch end or the adjuster end of the pushrod?

Re: Correct number plate for 1949

PM me if you need the info to use a single filament bulb in the MT110 as both Stop and Tail light - both the Red Hunter and 4G use a well tried system for this.


Paul

I am intrigued by the idea and have PM'd you.

Pete
