Fitting rev counter to 1.1uno carb model - Motorcycles

Hey there!
Upgrading your Toyota Tazz 2003 with a cluster that includes a tachometer (rev counter) is a cool idea. It can give you better control and insight into your engine's performance. However, you'll need to be careful when swapping out your cluster.
To get a cluster that fits and works properly, you should try to find one from a similar model or year. In this case, you'd ideally want a cluster from another Toyota Tazz 2003 or a similar model within the same generation.
Swapping clusters from different car models can be tricky because the wiring and compatibility may not match. It's important to make sure that the new cluster's connectors, sensors, and wiring are compatible with your Tazz's existing setup. Otherwise, you might encounter electrical issues or inaccurate readings.
If you're not sure which clusters are compatible, it's a good idea to consult with a mechanic or an automotive specialist. They can provide guidance on finding the right cluster and help you with the installation to ensure everything works seamlessly.
Remember, modifying your car's electrical systems should be done carefully to avoid any potential problems. Good luck with your upgrade, and enjoy having that rev counter on your Toyota Tazz!

I am not familiar with this model but petrol engines usually use a signal from the ignition system for the rev counter and diesels need a special sensor. However the rev counter is almost certainly unsuitable because petrol engines tend to rev much higher than diesels.

Its a diesel and didnt know the alternator controlled the RPM ,i thought it was controlled by the wire going to no3 injector on older models

This is no code I recognize

It mite be the idel screw on the carb

Your Ryobi SS30 is starving for fuel. Depending on which carb they installed on your trimmer will determine the needed repair. If your carb has adjustable jets on it, remove the plastic locks from the screws, and turn the low side (closest to cylinder) counter-clockwise 1/4 turn and test run. Turn out another 1/4 turn if necessary. If this doesn't solve the issue, or if your carb has non adjustable jets, then the carb must be rebuilt or replaced.
Good luck!

lots of old cars were + earth but not all .dont think this will make any difference ,is this rev counter for a 6 pot or four?? check terminals on back of unit??does one look as though it the earth ?? if not then one goes to earth and the other goes to the points side of the coil.easy

this may be a bad connection behind the clocks ,, because the main ecu runs the rev counters ., or the new rev counter may be faulty

Your problem sounds as if the thermo sensor....which controls the air fuel ratio when engine is cold....is faulty. It is a common fault on this model.
This is not an expensive part, and takes only a short time to fit.
Good luck
