 |
|
As followers to the OCC Youtube channel may have spotted already, this is the newest addition here at HQ, replacing the Dodge tourer that went recently.
I wanted to get something in decent condition that was also interesting to me, and liked by the rest of the clan. This British-assembled 4CV, or technically Renault 750 as it was known here, seems to fit the bill. It was registered in 1954 although the chassis number suggests that it probably first broke cover, in knocked-down form, in 1953, before coming to the UK for assembly at Renault's Acton facility.
Overall it's in presentable condition and drives well, bar a tendency to cut out once warm when coming to a halt. Giving it a touch of choke cures it so I assume there's a blocked jet somewhere, it has a Weber carb which I don't think is standard so I'll need to find notes on it before I delve too deeply.
The following vid walks around it before we head off to a car meet.

Its weird being the same age as old people.
You are either part of the problem or part of the solution |

Well done, Rick. You know a good car when you see one! I didn't know they did a RHD version.
Lovely! |

Can only be a handful of Acton cars left. !
I noticed that the late John Bolster's 4CV is up for sale; that is an Acton built car. |

| The first car I worked on in Australia was to change the engine in a Renault 750 for a reconditioned short motor. It went well until after I installed the reconditioned motor and found there were no cam followers in it. I rang the Renault dealer in Melbourne and they told me I should have taken the ones out of the removed engine. When I asked for the old ones they told me the engine had already left them and they were not interested in pursuing the cam followers but sold me a new set!! And it was not even my car, I was doing it for a friend who had no mechanical knowledge, after being ripped off by the dealer who sold it to him with the dodgy engine. I found it to be not a very comfortable car to drive. |

That looks really nice.
I believe the original carburettor was a Solex and either of these:
22BIC, choke 18, main jet 100, air corr. 165K, slow run 40, starter 95
or it was 22ICBT, 16, 82.5, 160K, 35, 95

I have noticed a number of different old cars that have changed their downdraught original carbs for a more modern [easily available new, I suspect?] carb from the Weber ranges.
Original? They 'work!'
Weber? They work, 'better?'
Is the engine the old 'Ventoux[?]' engine? Or is the ''one-two'' engine a later incarnation?
I once briefly had a Dauphine...What a difference the ride was when compared to my previous bunch of Morris Minors!
I've also had a 5, a 14[cheap n nasty]...and a 4 [TL] The 4 was by far the best French car I've ever owned.

I could see what was happening with Austin Sevens. Owners found they could improve the performance slightly by fitting a later manifold and side draught carb. I made a conscious decision to keep everything original which I believe puts me in the minority.
I achieved some additional performance by tuning the engine and matching the ports. I found a restriction in the up draught inlet tract that could usefully be relieved but basically "trundles" is original.
Once you get the originality bug however...... |

Fortunately the jets on the carb are nice and easy to get at without having to remove anything.
Last time we had the car out, it had a tendency to conk out when coming to a halt, only using a bit of choke kept it running.
Today I removed the idle jet and gave it a blow through, touch wood it now idles better although the only real test is to take it down the road. However the gritter came by twice earlier today, so that plan has been put on hold for a while.
