2+2 Carburettor

[Nigel Plant]

Hi folks
Two questions, weber 32 dft 1985 XR2 CVH 1.6:
1) I am suspicious that the main jets have at some point been confused. The primary is 160 and secondary 150, going by numbers stamped on top. My understanding is that primary should be the smaller one. Can anyone pse confirm.
2) What is the live source for the wire going onto the choke please. Having a few choke woes.

Regards
Nigel

The electronic choke and fuel cutoff solenoid are both feed from the same
ignition feed as the ignition coil.

Thanks Jim. Interesting, fuel shut off os fine but choke wire as dead as a dodo. Any reason I shouldn't just branch a wire off the fuel shut off? We are talking about the carburettor fuel shut off aren't we?

[Jim Hearne]

Interesting.
They should just join into the black ignition coil feed wire inside the loom
where it runs along the bulkhead.

So could I just branch another wire onto the choke from the fuel cut off. Seems basic, but can't find any info on my Haynes wiring diagram for choke.

Hi Nigel.

The Haynes manual has the numbers you state but doesn't define which is which - I would assume the main jet was first, but you never know.

Anyway I've attached a scan of the bit from the manual - hope it helps.

Thanks Dave.

This helps. I hadn't  spotted this in Haynes.  I  was getting confused between air and fuel jet sizes.  I combined all sources of info and concluded mine are correct.  All problems now solved.

Have live to choke, reset it and it now works fine.

Was not getting full throttle, adjuster screw/ clip where cable outer attached to carb was crackered. Temporarily fixed with novel use of cable tie.

Thanks all for
