Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing DVG 32/36 overhaul

No, not jetted the same, the original carb should have the marking 5A stamped on the base flange, this denotes its set up for 1600 crossflow (and also the 1600 Pinto)

Thanks for that. I'll have a look. No idea what may have been modified in it's 48 year life. Some engine work must have been done as there is no engine number on the top of the block.

I'd be more surprised if you actually find an engine number!

My 1971 4/4 doesn't have an engine number and as the car was bought new by my Dad we know he engine has never been changed!

There's a stamping on the bonnet flange which matches the engine number in the logbook so presumably the engines were supplied with a dispatch ticket by Fords Industrial Engines division!

I've got a number stamped on the rear of the block just above the bell housing. Always been a bit of a mystery to me.

I have stripped a 32/36 DGV several times and also the earlier 28/36 DCD which I am currently using. The Haynes book on Webers is a useful read. There are two good Weber agents who sell kits and parts - Southern Carburettors and WebCon; I have no connection with either company. Google for address.
I queried the E5 v E10 question with them, and was told that Weber has done extensive E5/E10 tests on their Carbs and kits with no effects of degradation. Stripping is easy and cleanliness essential. The jetting of the carb is specific to the engine model it is fitted on. I hope this helps.

Guilty of another thread drift..sorry. Arwyn, I had an old TR block out of a Flat Rad/Twin spare on which it seems the habit at the time was to stamp ME as a prefix to the engine number, which I think related to Morgan Engine. I also had a Mangoletsi modified (1500cc?) Ford in a boat I once owned which was devoid of engine numbers in the usual place. Perhaps just muddying the waters again..?

Re: Engine number and number on bonnet flange. The stamping on the Ford engines (mine is a 1971 4/4 also with 711M 1600 block) is rarely a good clear stamping and quite often gets machined away if subsequent work has been done. My understanding is that because the bonnets were manufactured specifically for each car, they had the last few digits of the engine number stamped to ensure they were returned to the correct car after spraying. The engine number ticket label was the most visible number to the MMC build team. The chassis number at this time would have been covered by the seats and not so visible. The wooden body also had a number which was stamped on the inner face of rear wooden body frame
and/or spare wheel area; & also the rear of the dashboard.
I hope this helps.

With regard to engine number on the bonnet flange, mine reads 1964 1694. The latter number being the last four digits of the engine number on the V5. No idea what the first number is unless the guy got the digits reversed and didn’t have an X to cross them out! Thanks for pointing out where the number is as I thought that the bonnet had been replaced as it doesn’t fit well.
Regarding the carb I’ve just found the pipe to the distributor has a massive split in it where it fits to the carb so probably a weak mixture.

Where will I find the jet sizes for my ‘74 4/4 documented if they are application specific.

I suggest the MMC fitter was having a bad day.
The jetting for your carb will be (should be) the same as the Ford model that used the engine at that time; probably the 1600Gt version of Mexico, Cortina or Capri. Unless of course your car has been modified or perhaps rolling road tuned which may then have had a jet size change to suit.
Send me an email offline (malvern3104@outlook.com) and I will let you have a copy of the standard jetting used.
The 32/36 carb has fixed Venturi chokes, many carbs allow these to be changed.

Just started to strip down the carb. Found the full power valve was assembled with the diaphram/gasket folded under so was totally useless for it's purpose. Having to order another one of those as not included in the service kit.

Having looked at the jetting I'm a bit confused.
Listed in 1600GT then my carb order

Primary main jet 140. 140
Secondary main jet. 135. 140
Pri. air corr. jet 165. 175
Sec. air corr. jet. 160. 185
Pri. Emulsion tube. F50. F6
Sec. emulsion tube. F6. F6
Pri. idle jet. 55. 45
Sec. idle jet. 50. 50
Pum jet. 50. 45

Has someone just fitted any old DGV (part number only says "32/36 DGV")?

Can anyone suggest where I might get some insight into these values?
