Hi all,

can anyone help me with the correct gap setting when adjusting points for a rover P4 80.
Any advice on correct setting for the carburettor would be greatly appreciated.'

Regards,

Pete
 
.014 to .016 inches is correct but the metric equivalent is not as stated but is 0.35mm - 0.4mm . Most people set them a little narrower, say 0.012 inches, to allow for a little eccentricity in the shaft motion caused by worn bushes

my response was figures from pdf of manual for p4
 
Symes : your pdf I'm afraid is misleading you . It is a matter of simple arithmetic . 1mm = 40thou ( actually 39.37 thou to be absolutely accurate ) . Therefore 14 thou = 0.355mm and 16 thou = 0.406mm
 
are you also aware of the guild forum , also on facebook , http://roverp4dg.org.uk/ , the same engine was used in the land rover ,im sure you would also get help there , i think the original carb was junked quite often and replaced by a weber if im not mistaken
 
Looks like you have the points gap info, so to carburettor. I don't have specific '80' info., as I run a 1950 75 and a 1959 100, both of which use S.U's.

I would suggest contacting the Rover Car Club of Australia and/or the Rover P4 Driver's Guild. Members in both clubs have a wealth of Rover information readily available to fellow members.
Good Luck,
Dane.
 
Thanks for the advice, P4 is much happier..
I do have another question, with regard to the electric overdrive, recently has stopped working. However, have noticed since this has stopped working there is a high pitched squeal coming from somewhere under the vehicle… Would appreciate any thoughts comments anyone may have, as i'm sure will save me a lot of time.

Much appreciated.

Cheers,
 
Make absolutely sure that the OD has disengaged, by taking off the side cover of the solenoid - usually on the lhs of the OD unit, and seeing that the vertical lever is in a near enough vertical position with free play between it and the solenoid plunger which runs horizontally . If the OD has got stuck , under no circumstances must the car be reversed , as it will probably destroy the one way clutch, which results in a complete loss of drive
 
I definitely agree with Christopher's suggestion, and also check your gearbox oil level. G/box and overdrive should be interconnected for oil. The squeal worries me, so examine and check everything before trying to drive anywhere.

Dane.
