Hi, still waiting for the new battery to arrive but I've got another problem and it's electrical which as mentioned earlier is definitely not my forte. I've bought a rear tail/stop light. The light works ok (i keep charging the faulty battery) when I press the brake the rear light should get brighter but the light actually goes out. I bought a new rear brake switch but still the same. When I put the parking light on, the brighter light comes on. I've tried different combinations of the rear wiring but it doesn't seem to make a difference. Any ideas anyone
Thanks....Pete

Wow thanks for the quick reply and I'll try exactly what you have said. Just one thing, choke off.....is that open. I tend to get this the wrong way round. Does choke off mean fully open and choke on mean fully closed

UPDATE......
Hi, anyone following this thread will know that I got the bike running. Well not anymore. It was ticking over nice then suddenly stopped and will not start for love nor money.....and I've tried both.
I've stripped the carbs down....again and I definitely have fuel to the plugs.
Done the points gap and timing again
Cleaned the plugs and made sure there's sparking against the engine fins
One thing tho, I bought s new 6volt gel battery and i noticed it was losing charge. Took it off the bike to make sure it wasn't parasitic power that was draining it. Charged it up and left in on the work bench and within 15 minutes if had dropped from 6.3v yo 5.7v. I emailed the company who said this was faulty and are sending out a new battery.
Could it be that the faulty battery is causing a reduced spark at plugs?.
I was of the understanding that these old kick start Honda's were self generating and therefore technically you didn't need a battery to run. Am i wrong on this?
Anyway, when the new battery comes I'll try starting it again but ive wasted 2 days trying stuff and got nowhere and at the minute I'm totally stumped.
Please help

IT'S A RUNNER...........
Swapped over the coil leads and it started first time. Got a bit of an oil leak from the clutch casing when the oil pressure is raised. (Weird cos it's a new gasket on there) maybe just want nipping up. But any way, brilliant felling when it started up and kept running, good tick over. So I've decided to treat it to some new exhausts, new brakes, sort out the back end and a few bits should see it just about there.
Thanks for all the advice, tips etc. I'll post more pics when it's fully completed
Pete

Bryan regarding your post. I do have a spark at the plugs. Are you saying that if I have the wires wrong way round I wouldn't get a spark at all. I'm confused

K2 yes there are 2 sets of points and 2 coils. Are you saying that the earth is not common and by plugging in to wrong earth connection can cause 180 degree out

K2_k6 you read my mind cos I was just coming on here to ask that very question. What if I've coupled the coils into the wrong power lead. Normally with double coils there is a blue and an earth on one coil and a yellow and earth on the other so you couple them up the right way into the harness. The coils are identical other than this.on my bike, both coils had a blue and an earth. Could it be that I've coupled them up back to front causing 180 degrees misalignment.

K2-k6, tried the carb cleaner spray but didn't make any difference. Still the odd fart of a combustion but nothing more than that. Not sure what to do next. I've checked the timing for the 18th time and it's okay.

K2-k6 you mentioned spraying carb cleaner etc down the carbs but where from. Do I take the air filter off and spray from that route or do i take the throttle cables off and spray down the barrel of the carb ?. Cheers

Hi everyone. A quick update. I've now got the electrics something like and managed to get a spark to plugs and points. However, the thing will not start. It does the odd fart but other than that I'm left with an aching thigh after all the kicking over. I'm thinking it's possibly fuel to the plugs. When i take out the plugs (which along with the points are new), there is a hint of a whiff of petrol on them but they're certainly not soaked. Could it be a carburettor problem. The bike is a twin and I couldn't find any original carbs so bought 2 singles. As far as I know, and I could be wrong, the original were 2 singles with a linkage joining the choke arms together so that when one choke is operated it engages the second one as well. So I've made s little arm myself to link the 2 choke arms. Am I missing something. Thanks in advance.

Cheers Dennis. It's turning out pretty good. It's a costly hobby tho this ere bike renovation. Also I've yet to try and start it as I don't have a spark to the plugs so I'll let you know what the engine is like when I get to that stage
