A puzzle of carburettors..

[sarran1955]

Hello,

Killing time in the warm sunshine......

Before going ski ing this week end...

I attended to my red single seater with 24 " wheels....



With his 1953 Solex 22mm carb..



and 'Tuning' air filter..



and so we turn to the next 80-90 project...

A puzzle of carbs...

2 Solex Pist 34/4's.. with a heap of new bits.. including (at the top of the image) a rebushing kit...



I think there will be a video here..

That Massey Harris is a classic. Enjoy your skiing weekend John and keep those videos going.

Have you sussed out that heater yet or have the big toys taken precedence?

Hello,

Have you sussed out that heater yet or have the big toys taken precedence?

I have to confess.... the Eberspacher is sitting on a trolley..

heating the workshop...

The van is 'as was'..

and I have some new (to me) lightweight touring skis to try..

This week end the Parisians have gone home from 1/2 term holiday..so things will be a lot quieter..

As I've said on Camping.. it only takes too many people at once to swamp small tourist sites..

So it will be 'les Crouzets' Camping municipale (13€) for me..

Hello,

Well, I had my few days off ski ing..

As usual..one Kombi amongst the white buses..



Here is the 'dammeuse' going to tidy the pistes..



there is a great view from the volcano..



and so....back to the workshop....

Where I have been solving..a puzzle of carburettors...

Here is my 'spare' Pict 34/4 carb..



These were excellent carbs.. used mostly on California spec beetles around 1974..

Basically an uprated 33, with a 28 mm venturi and different mountings and throttle control..

(not inter changeable)..

By the time VW dusted their stock off in 1979.. to fit to the CT 1600 engine.. they made 2 modifications..

First ..the cold weather accelerator pump booster..seen below..



Which in California was a 'heat slug' device.. like this..



sadly NLA, but on the CT they decided to to use a vacuum operated switch powered off the aircleaner..

it increases the 'dose' of petrol when accelerating from cold..

Secondly the 'anti VW throttle blip syndrome' damper..



This 'wheesey' artifice will also only work if the whole air box system is in good condition..

And so to the puzzle...



One would at first look..say..this is great, there is enough to build 2 carbs here..

Not so simple..



As indicated by the pointer..the choke butterfly is jammed open by the simple means of.....

twisting the mechanism out of shape....

Notice the new gasket and aftermarket float valve..

On one body.. the vacuum switch screw threads are ruined..great place for a fuel leak..



It gets better.. to try to 'rebush' the throttle spindle the screws have been 'got at'..



So..looking at the rest of the overhaul kit..(Empi Chinese)..

There is not much I can use..the gaskets are all for other models..



The replacement mixture screw is not well made..



There is no new 'emulsion tube'..and the old one is a bit crushed..



Needs a new 'pilot jet'...the ball bearing is jammed..



Main jet worn out.. and attacked by a mega screwdriver..



So...

I have been in touch with Jeff Carter at Gower and Lee..

The good news is that all the needed parts are available

Service kit £26.50
Standard main jet £5.50
Larger 130 main jet £5.50 each
Pilot jet £5.50
Air corrector/emulsion tube £6.50
We also stock floats, choke units & fuel shut off solenoid.
However, the thermo switch is no longer available from Solex/Pierburg in Germany.
Prices subject to carriage & VAT.

Tomorrow I will check out the 12 volt bits...shut off solenoid and choke...

Then we make a shopping list..
