Dipped the plug in gas and it tuned over a little better

Ummm, wouldn't that suggest that fuel may not have been present before? Pushing it faster or changing what you are doing is not a good idea - don't change multiple variables when you are trying to solve a problem cos you don't know which variable you changed provided the different result, in this case adding the fuel or pushing faster. Sounds like you have a fueling problem perhaps? Try again pushing as before and adding a bit of fuel to the cylinder? Cheers.

The plug has to be grounded to spark, right? I can't really tell while running along trying to push the bike but if I leave it overnight it should be pretty fully charged and if it doesn't go then that's spark going, must be gas. I think it will be battery though, i haven't really done anything since the battery went flat. Just one more question: Do car 6v chargers charge better/faster then little trickle chargers? The dude that charged it the first time used a car charger for 1 and a half hours and it ran fine, this one has been on for 4-5 hours and not strong enough

Well after a few pushes more I can assume the gas on the plug had gone and while still pushing it fast it made no difference.

The plug does.
I use an aligator clip kinda thing for a one person pushstart check.
If you have a good stand you can put it on that and spin the wheel watching you dont munt you hand.

Maybe aye, I think some of those fancy ones switch off when they think it is full and all that shit, I have found seemingly fucked batteries can sometimes come back from the dead with a good week long blast on an old charger. (making sure it stays topped up of course)

So with the fuel it turned over better, without it it didn't regardles how quick u pushed .....

[wbks]

I don't think I wrote that clearly enough: Although it originally ran better with gas on the plug, I was pushing harder than usual. Some time after when I can only assume the gas on the plug had evaporated I pushed it at the same pace as with the gas on the plug and it was exactly the same.

[koba]

Try check the spark then.
If you think the battery is dodgy get a new oneand try that, it pays to have aspare if you run total loss anyway.
I just got a new small 6v battery for the A and it was $24 from repco!
( but they did say it was the last in the country so I may have beat you to it!)

if it's points ignition andd a battery you don't need to push the bike to check the spark. Just remove plug, rest the plug (cable connected) on an earthy thing. Remove the little cover over the points, and turn the engine until the points are closed. Now flick the points open with a small screwdriver. You should get a nice fat spark at the plug. Nice simple things points ignition. (any ignition switch on while doing this of course)

With their weak ignitions from stock the Honda 4-strokes are notoriously cold blooded. Twins seem to suffer particularly from this and may take some time running on 1.5 cylinders before they bark away on both. Sooo . . . . do you still have the choke fitted to the carb and is it the stock carb? I've found a useful little trick is to give it a good slosh of fuel down the carb with the throttle wide open so the engine is well and truly flooded. Then try push starting it with the choke off and the throttle wide open. It won't start initially as it's flooded but as it turns over the excess fuel is purged to the point where it will at least give a good splutter. If it won't splutter of fire up you have some problem other than fuel.

If it's seriously screwed up you can get very impressive flames out the carb, so I'm told.

[wbks]

Choke is fitted and as far as I'm aware it is stock carb'. Every time I've tried to start it cold without choke it just locks the wheel and doesn't seem to want to move, just skids. I'll try the fuel down the carb and pushstart thing.

That is a good thing!
It is probably a wee bit light to push against the compression of the engine so as you are pushing it in gear with the clutch in get up some speed and as you let the clutch leaver off jump onto the seat of the bike sidesaddle styles to put some weight on it momentarily.
If you time it right there should be enough grip on the back tyre to overcome the initial resistance of compression.
If it doesn't start at this point it should be harder to push and make a different sound. (as the engine is now turning)
If it is skidding with the clutch in try adjusting the clutch or just giving it a wee bump on the seat as yo get it started.

If the rear wheel locks up try a higher gear, you should be using second anyway but if it locks up in second use third. If it still locks up then push faster!!

[wbks]

Left it on overnight and it's still not doing anything. The problem is that it turns over but just slows down to a stop as it slows down so basically it's dead. Yes I have been bouncing on the seat as I drop the clutch and I've been trying second but it's the same every time. So either this is the SECOND battery I've bought that doesn't work or something else is wrong.

[wbks]

Did what Ixion said and the spark seemed pretty inconsistant. A few blueish white sparks but didn't exactly span the whole spark point and the rest were orange sparks that were sparking down in between the middle of the plug and the wall if that makes sense. Would that be enough to ignite the gas?

[SHELRACING]

I don't really get what you mean by the points, Ixion.

You really need to convert to to 12volts. Its not that hard. Change the coil, From another bike. We ran our CB100 single fine on a Car coil. Get a 12 volt battery. A bike battery or cheaper option,Commonly can get a 12v battery from a J.A Russell they are used in house alarm systems and are perfect (charge them with a phone charger)

Check your points gap set to about 16thou. Ixion is right give the points a flick (when closed, ignition on) you should see a small spark across the points

When you have run down the road, is the plug wet? if it's wet you have fuel. if it's not you have a fuel problem. There should be a screw at the bottom of the float bowl. Loosen it if fuel comes out sweet. if not you have a blockage.

If you have fuel, and you have 12volts. and it don't go. you have a timing problem. Valves, check your valve gear allignment, or ignition check your points should be opening near top dead centre on the compression stroke. ie you can feel both the rocker arms just move.

Check all that and it will run.
