engine won't rev

[hibbo]

Hi Hibbo

If you take 1934 box saloon with standard gearing and can get the engine to do 4000 RPM (about the realistic maximum), the speed in gears will be 13 in 1st, 22 in 2nd, 35 in 3rd and 59 in top.

It sounds as though your car is power limited rather than RPM limited, which suggests insufficient fuel or air flow rather than an ignition problem.  There's little to go wrong with the air inlet side (assuming the choke flap is working properly), and a blocked exhaust seems to have been ruled out, so that leaves a restricted fuel supply to investigate.  This is consistent with the choke use having a beneficial effect, as it will counter the mixture weakening by restricting the air supply to match so at least you have a decent air/fuel ratio even if there isn't much of it !

Look for blocked jets, blocked carb passages, blocked pipes and blocked filters.  There is a gauze filter in the bottom of the petrol tank over the inlet pipe, but many have been poked through in the past.  There are also gauze filters in the petrol pump and the inlet banjo on the carb.

Thanks for your suggestions I will work though them.

Graham

Another question-- How old is the fuel? . I had this problem years ago and after I tried fresh fuel all was well.

Thanks Ken but the fuel is fresh.

Sounds like a definite restriction in fuel supply.  As you've already cleaned the carb many times, i would do As John Cornforth said and make sure there is no restriction in the fuel pipe gauze.

Modern fuel gels terribly and we found that after just a few months, the top of the fuel pump (with the 1-way valves) was completely blocked with crud. Give that a go

Thanks, will do.
