The Triumph 2000/2500/2.5 Register Forum

Hello llessur,

personally if it's running well enough and as you say there are no other signs then I would run it and keep an eye on the oil and water. Although not a major job to change a head gasket it would seem a pity if you remove the head and find no problem?

Hello llessur, the thing to remember is that the mixture affects the timing required so set the mixture first. They should not need much adjustment from the factory setting, if they do there is something wrong somewhere. Dynamic timing as Tony suggested is a good way to go. If you have a timing ligh...

Hello llessur,

I wouldn't worry too much at those, from your last post it's only 0.4 volts. I would say your battery is not fully charged as it should be over 13 volts.

Hello Carboy0,

why not try weakening the mixture a bit first? If it's rich thoughout the range it doesn't sound as though the needles are far off?

Hello Llessur, you may have a malfunctioning night dipping relay. It is mounted in the boot, probably left hand side near the hinges? (Memory failure) It should only operate when the lights are on and puts a resistor in line to dim the indicators and brake lights. By pass this and see what results y...

Hello Peter, normally when cranking there is a feed from the starter motor directly to the coil, which bypasses the ballast. You say you have 12 volts and 8 volts when cranking which seems to eliminate the ignition switch. This starter feed to the coil should connect on the coil side of the resistor...

Hello Cliff,

yes you are right, the Triumph springs are flat ended, as were most of that era. Modern springs often do not hav ethis feature but teh spring pans are shaped to accomodate this feature.

Hello Llessur,

10 amps is more than ample, the coil only takes an amp, possibly less?
The distance is short anyway so the voltage drop will be tiny.

Hello Llessur, is the rubber the correct size, as often metric sizes are said to be the equivelant of imperial but are usually a bit smaller? One trick I've seen but not tried is to block the solid pipe at one end, push the hose on the other with it connected to an air supply, the pressure tends to ...

Hello Cliff, yes, it's the position that the case is when doing this check. Essentially it means the pinion and crown wheel are properly meshed and the only other adjustment required is to set the back lash. I can make an informed guess using the old and new components but at the end of the day I ma...
