AidanT Posted June 29 Author Report Share Posted June 29 Hi Another question I have a high torque starter from thd club, had no problem with it on the last engine, it worked perfectly. On the new its just spinning. Q1 Do, they / should I have done some maintenance on it prior to the refit as it's not been run for s few years? Q2 I fitted it with the spacer I had with the old engine, could this be the issue? TIA Aidan Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 29 Report Share Posted June 29 most need the spacer and shims but is it actually firing the pinion out into mesh or spinning without any attempt to mesh as you say it spins , can you do a bench test to see if the solenoid is moving the pinion out to make mesh or not Pete Link to comment Share on other sites More sharing options...
JohnD Posted June 29 Report Share Posted June 29 How is it wired? Original was permanent live cable to starter motor. Feed from starter switch to the starter pinion solenoid. Once the piniknis trown into mesh, the solenoid completes the high current circuit internally to turn the motor. On a Triumph you can keep the feed from the external starter solenoid switch to the starter, the one on the bulkhead, and add a jumper from that to the solenoid. Then the starter button/ignition switch activates the bulkhead solenoid switch, makes the cable live to the motor AND the solenoid. When in mesh, the motor is connected. Do you have the jumper?

AidanT Posted June 29 Author Report Share Posted June 29 (edited) Pete Bench test just run and it's throwing out perfectly Measured the distance to the fly wheel, 12mm, measured the drive position at rest 10mm. So as far as I can see it should work. JonD, I've not changed the wiring from the previous set up, positive though the solenoid and engine earth. It is working, just from the sound not engaging. I have fully charged the battery. I'm a little bemused!!! Aidan Just thought, the solenoid is on a wire from where the main power connects to the starter- that nut wasn't very tight.... maybe the solenoid wasn't being engaged...??

AidanT Posted June 29 Author Report Share Posted June 29 Another thought for tomorrow, can you static time with electronic ignition as touch would with points?? Tia Link to comment Share on other sites More sharing options...
johny Posted June 29 Report Share Posted June 29 In my experience you can although it might depend on the type of electronic ignition. Its not so easy because it seems to 'fire' so the multimeter or bulb just flickers rather than staying energised/denergised like it would with points. This makes it more difficult to get it exact but is good enough to get to run and then use a strobe👍 Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted June 30 Report Share Posted June 30 I have static timed my GT6 which has electronic, contactless ignition but the magnetic trigger has six points on it which are clearly visible and can be aligned to the sensor. The Sixfire's magnetic trigger (which replaces the points) is completely spherical and so I need to use the old bulb on a wire technique. This is only for guidance as I then use my Gunson and dynamically time the ignition. Link to comment Share on other sites More sharing options...
AidanT Posted June 30 Author Report Share Posted June 30 So Just a quick update and a thank you to all that have helped so far. Starter now turning the engine over nicely. Oil pump working well. Dizzy installed correctly with the correct depth set. Just requires static timing, installing the plugs and see what occurs!! Just to say this has been an excellent experience, my first engine nut and bolt rebuild over nearly six months doing two three hours each weekend Link to comment Share on other sites More sharing options...
AidanT Posted July 2 Author Report Share Posted July 2 Hi again, Advice on Engine oil please? I know I will need to change after "Running in" but do I still need to use 20W50 with a rebuilt engine? TIA Link to comment Share on other sites More sharing options...
JohnD Posted July 2 Report Share Posted July 2 Of course! Cars that are used for only a few thousand miles a year may need annual changes, even with the best oils.

Tia Hi all Not able to set the static using thd std method, light doesn't even flicker! Any other methods please? I could set it by eye I guess but how accurate does it need to be??

Iain T Posted July 5 Report Share Posted July 5 Correct ignition timing is number one process in getting your engine running correctly. You really need to borrow or buy a strobe gun. Iain Link to comment Share on other sites More sharing options...
johny Posted July 5 Report Share Posted July 5 Ok how about removing all plugs and then connect number one lead to a plug touching earth. With ignition on turn engine over by hand watching timing mark and the plug. Adjust to produce spark at right position... Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 5 Report Share Posted July 5 every simple electronic points ive come across will flash the small test bulb as it triggers if you have no flash you could have wiring logic incorrect but if it fires and runs adjust the dizzy to give best running and retard it a good bit from best , test drive & check for pinking Pete Link to comment Share on other sites More sharing options...
AidanT Posted July 6 Author Report Share Posted July 6 Very Heath Robinson, bit I think the static timing is now set thanks Will just about start, but no banana Looking at fuel, the plugs look dryish and there is fuel dripping from the air intakes. Have I got the dreaded rubber shavings?I replaced all the intake gaskets, could I have an air leak maybe? I can't see an easy way to tell if I have tightened up the carbs to the inlet manifold Any suggestions on that front?? TIA Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 6 Report Share Posted July 6 (edited) fuel dripping from the intake throat has to be fuel levels playing up, cant see thats anything connected to manifold or carb gaskets can be upset by ragged idle lumpiness the shake upsets the float needles Pete Edited July 6 by Pete Lewis Link to comment Share on other sites More sharing options...

Ordered some easy start, I can hear it wanting to start, but it just can't make it. Think I'll use some brand new plugs to. I cleaned up the old ones but spanking new will give it no excuse!! Any other yhoughts most welcome 🙏 Aidan Link to comment Share on other sites More sharing options...
Stratton Jimmer Posted July 7 Report Share Posted July 7 19 hours ago, AidanT said: I can't see an easy way to tell if I have tightened up the carbs to the inlet manifold Any suggestions on that front?? Providing the engine will start, upward pressure with the hand under the carb will often cause or stop manifold air leaks. You will know by the change in sound. I had a recent induction roar on the sixfire and just a wee bit of upward pressure on the front carb showed the air leak to be there. The gasket had tiny tear in it.

Stratton Jimmer Posted July 9 Report Share Posted July 9 (edited) It was the carb to manifold gasket. Actually it was the carb to spacer gasket. Edited July 9 by Stratton Jimmer Additional information added. Link to comment Share on other sites More sharing options...

AidanT Posted July 12 Author Report Share Posted July 12 Hi all How do you test a coil? Checked it has a good supply but I think its not creating any output- I have a strobe but its cheap snd may not be working but no flash even on the coil ht lead Could possibly be related to my static timing issue above?? I can't see a spark on the plugs either!! Aidan Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 12 Report Share Posted July 12 does rather sound like the coil is dead remember the coil only discharges HT when you dump the earth/dizzy line just powering the 12v wont do much Pete Link to comment Share on other sites More sharing options...
AidanT Posted July 12 Author Report Share Posted July 12 (edited) 35 minutes ago, Pete Lewis said: does rather sound like the coil is dead remember the coil only discharges HT when you dump the earth/dizzy line just powering the 12v wont do much Pete So I put the coil lead to earth and turned over (electronic ignition) and got sparks. Still nothing at the plug.. Swap back to points?? Edited July 12 by AidanT Link to comment Share on other sites More sharing options...
AidanT Posted July 13 Author Report Share Posted July 13 I think I'm defeated! Anyone in the Grantham area that could come and help me please? It's firing on occasions but not enough to catch, getting a spark at the plugs, and I think the timing is OK, but not sure on that Complete novice on the carb front, although I have sprayed quick start down the intakes, but it didn't make s blind bit of difference. Spark at no1 plug but needs the light off in the garage to see it. Don't know if I'm flooding it. Beer tea coffee chocolate or whatever I can buy at the local coop as a bribe 😊 Aidan Link to comment Share on other sites More sharing options...
