Quack Posted April 20, 2022 Report Share Posted April 20, 2022 My idle has always been 1000rpm, however it’s now sitting 300-500 higher and my temp gauge is nearly halfway! Engine also starting to sound a bit more sluggish to start, the motor takes a bit more whirring before it kicks in. Not sure if related but any ideas about the temp gauge and rpm??

Iain T Posted April 20, 2022 Report Share Posted April 20, 2022 Could it be a throttle issue? Something not returning or stuck? I remember when I first bought my car the tickover was high and I tried to reduce it at the carb but discovered the cable wasn't snagging! The first of many many problems.............

Quack Posted April 20, 2022 Author Report Share Posted April 20, 2022 Is this likely to be causing the temp gauge issues as well? It’s bad. Was fine yesterday but now I can’t even get up to 30mph in 3rd gear before it goes above 2000rpm, needing to change up to 4th Link to comment Share on other sites More sharing options...

Check, oil, water for levels discolouration. Does the temp gauge rise to halfway straight after starting from cold? Link to comment Share on other sites More sharing options...
Quack Posted April 20, 2022 Author Report Share Posted April 20, 2022 I’ll check temp gauge tomorrow morning again from cold. And the engine runs but like I say the revs driving are higher too. Yesterday I could get to 30mph at 2000rpm but now can’t reach 30mph before 2000rpm Link to comment Share on other sites More sharing options...

So what exactly do you mean by the above? Do you, perhaps, mean that the tacho is now overreading? Link to comment Share on other sites More sharing options...
Quack Posted April 20, 2022 Author Report Share Posted April 20, 2022 Ignore the temp gauge stuff for now, i'll check it out tomorrow. It's the revs im concerned about. And what i mean is what im saying, i always idled at 1000rpm, now it's started idling higher, and when i drive it's also 400ish higher than it normally would be at each speed i go. This changed in the course of a day...surely that can't be normal? And as i mentioned at the start, the engine struggles more than it normally does to turn on, sometimes clicks out and need trying again, whereas before it would always start on the first turn, even if it took a while. Again im not sure if this is related but still thought i should mention. Link to comment Share on other sites More sharing options...
Iain T Posted April 20, 2022 Report Share Posted April 20, 2022 Mmmm, as I said check oil/water. From what you say about the engine struggling I may be serious. The higher rev counter reading may be wrong? Does it sound as though its revving higher than yesterday? The varying reading could suggest the counter is having a mental breakdown! They don't call them worry gauges for nothing! Link to comment Share on other sites More sharing options...
dougbgt6 Posted April 20, 2022 Report Share Posted April 20, 2022 Yeh, My thoughts too, what do your ears tell you? Doug Link to comment Share on other sites More sharing options...
Quack Posted April 20, 2022 Author Report Share Posted April 20, 2022 I’d say it definitely sounds like it’s straining more but I could of course be biased by what I’ve seen on the rpm counter. The fact that the arm is stable though tells me it’s not the counter, it sits very still at 1400 every time I started the engine today, there’s no jumping about.

Pete Lewis Posted April 21, 2022 Report Share Posted April 21, 2022 looking this is a 13/60 ??? so this is obviously an aftermarket add on electronic tachometer question where does this electronic unit get its impulse from ??? the HT coil or the alternator/dynamo i would think this is just mis reading giving you the wobbles as Rob says you cant change the driveline ratios being south how close are you to some who can help just seen you have on another post fitted an alternator. and are having other electrical problems Pete Link to comment Share on other sites More sharing options...
Wagger Posted April 21, 2022 Report Share Posted April 21, 2022 (edited) Disconnect the rev counter and drive it by ear. This definitely appears to be a fault with pulses to the Tacho. It is fooling you into driving at too few RPM making your car appear gutless. Edited April 21, 2022 by Wagger Typo 1 Link to comment Share on other sites More sharing options...

Good to know that it's likely just a misreading though...the tacho must be messing me around, i'll have to take a look at it and let you know where it gets it's impulses from today/tomorrow. It was just strange that it has always been fine up until now. I'm currently based in salisbury, wiltshire. I'll report back on here with pictures & videos of the where the tacho is linked up to, and my alternator wiring too. Cheers Link to comment Share on other sites More sharing options...

Just measure the voltage across the battery as you rev it up. I've had more than one where the regulator pack failed and it would throw up too high a voltage - extremely bright lights, fast indicators, etc. In my case, not enough to boil the battery and blow the lights, but they can if you're unlucky.

Pete Lewis Posted April 21, 2022 Report Share Posted April 21, 2022 aha Salisbury bit too far to dash out and have a look let us know what you unfold as the culprit with high voltages the fuel gauge will also read high as does the temp gauge it might wreck the gaugr voltage stabiliser they do get hot bot dont like to be cooked and if the alternator is absorbing more power than is needed that will affect performance by sapping engine output Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted April 21, 2022 Report Share Posted April 21, 2022 Q, The two nearest Area's to Salisbury are Andover and Wessex, about 20 miles to either. Andover meet 2nd Thursday, Wessex last Thursday. Worth a trip for advice, maybe even get a home visit. You don't have to be a member.

paul fosh Posted April 21, 2022 Report Share Posted April 21, 2022 check the choke is not stuck on a tad , had it with mine enough to make it run faster hotter bit less go worth a look paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 21, 2022 Report Share Posted April 21, 2022 and get some free play in the throttle cable as heat expands the outer sheath and this can speed up the idle but the culprit is looking more towards the alternator and its voltage Pete Link to comment Share on other sites More sharing options...

If it sounds high can you lower the idle with the throttle stop screw? Link to comment Share on other sites More sharing options...
Quack Posted April 22, 2022 Author Report Share Posted April 22, 2022 Voltmeter on way in post, meanwhile the tacho gets its pulse from the coil, the temp gauge seems to be back to normal today at start from cold. I’m going to get some coolant and refill the rad just incase. tacho revs still sitting a bit higher than normal but not as much as yesterday, will have to check again after a drive Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 22, 2022 Report Share Posted April 22, 2022 there have from a vague memory been problems with electronic add on tachometers interfering with the coil ign feed impulse if the power is misbehaving just disconnect the tacho for a simple test Pete Link to comment Share on other sites More sharing options...

Airlocks can cause wild temperature gauge readings. I don't know if the 13/60 sufferers the same problem as the 6 pots. I refill my rad from empty with the front end on ramps to try and stop airlocks. Link to comment Share on other sites More sharing options...
Iain T Posted April 23, 2022 Report Share Posted April 23, 2022 Sounds like the speedo needs a service? My original temperature gauge read high but when checked with a temp gun it was fine. Link to comment Share on other sites More sharing options...
Jeffds1360 Posted April 23, 2022 Report Share Posted April 23, 2022 Just read the original post and the high revs reminded me that when I got my car I had the same problem. After checking choke and throttle cables and idle screw I had no idea why it would not come below 1200rpm. Weeks later when changing air filter, I spotted that one of the two screws that hold the butterfly on the spindle was missing !!!. (Where it is ??? Who knows ) same size as meccano screws of which I have hundreds so, once replaced the revs are now down to 800 😀 Link to comment Share on other sites More sharing options...
