68 Triumph T100
....After searching and reading the posts< still can't start my chopper.. She wants to, but will run for 5 seconds once, then wants to start, but won't.. last try it started for 5 seconds then wouldn't even want to fire..
So let me start with the set up..
wiring diagram attached.. checked and rechecked. everything new except points and condensers. which is my next move.. I swiched startor wire as suggested in another post with no change. I rebuilt the carb.. bla, bla, bla...

HELP!!!!

no battery or battery eliminator?

Sparx regulator/rectifier/Battery eliminator

 

[edhaeuser]

Have you tried using a fully charged battery temporarily. If that works maybe check alternator output.

 

[Englishman]

If it's not the electrical, try starting it with your hand over the carb mouth.

Fuel cap vent?

 

[Goldy]

Not sure if it would really matter, but your coils are wired backwards.

Can you turn the lights off when starting it? Before I put a battery in mine it would run with the lights off, but would die when they were switched on. I'm running the Sparx rectifier too. I haven't put in my Wassell high output rotor/ stator yet, that might have solved the problem too but I just went with a tiny battery.

AIR, FUEL, SPARK....simple...you have got air...use starting fluid as a fuel(just to make sure) and spark. as stated above add a FULLY CHARGED battery..that will eliminate any problems with the "eliminator" or not enough voltage to fire....also recheck all grounds and solder any questionable connections.
Another member here had a somewhat similar problem....it was a temperamental switch..

run a battery temporarily.....triple check your wiring....make sure your timing is close....timing is key even if your carbs are slightly off it'll most likely run

Coil resistance is? More info needed.

 

[bobscogin]

Not sure if it would really matter, but your coils are wired backwards.

I noticed that too. If positive ground, positive side of coil should go to points, but I also wonder if it matters?

thanks.. I'm trying the coil wires tomorrow.. I'll follow up..

 

[kllrjo]

concentrics or monoblock carbs? doesnt really matter,BUT, the last bike i had that would fire then die,needed the main jet cleared......seems the alcohol [in this pisspoor fuel we are being sold] tends to leave a film or crust blocking the main jet......bike would fire when tickled, then die! i just pulled the plug from the float bowl [concentrics] and sprayed some cleaner into the main and it fired right up and ran great all night! multiple shut-downs and restarts, no prob!
what i did was to use spray carb cleaner, spray some at normal can position, then bend the straw up into the center of the float bowl, have your buddy hold the throttle open and spray.........might not be it, but easy enough to try!

reversed the coil wiring and fired with practically the weight of my foot on the kicker... THANKS for the help!!!!

 

[rockett]

Can we get a pic of the bike?
