mis reading speedo

[1300dolly]

The speedo on my fwd misreads, at 22mph it reads 30. at 29 mph it reads 35/36 mph. at stand still it reads about 5 mph but blipping the throttle sometimes makes it drop!!. at faster speeds (approx 70/75) it waves between 85 and 100.<br>
could this be a stretched cable? <br>
apart from that its running great (carbs need adjusting slighty) and maybe a service as i havn't done anything to the engine yet.<br>
<br>
all help and advice gratfully received

Justyn..Do you have the right final drive. Not sure this is a triumph problem but in the olden days (ahhh) it used to make a difference on minis. Also, dumb as it seems, do you have the right size wheels?<br>
<br>
I guess I'd change the speedo as well, just run one inside the car (ie out of the dash) and see what readings you get ..<br>

Probably the speedo head, if it's a 1300 FWD I've a couple of spare speedo's knocking about, usual question, where are you in the country, or are you going to TDCIR??<br>

.. you have something from your speedo! Mine isn't reading anything at all as the gearbox end seems chewed. New cable and still nothing!<br>
<br>
Must sort that out as I'm sick of working off the revs only!<br>

If the needle is fluctuating between 85 and 100mph, the head of the cable is knackered. Shouldn't dance around like that.<br>

More likely gearbox end. New cable either way I think.<br>

Hi there,<br>
<br>
I had the same problem when I fitted a Dolly 1300 gearbox in my Toledo. Remedy, fitted a Dolly 1300 speedo!, hey presto, 30 mph on the clock at 30 mph.<br>
<br>
Sorted!.<br>
