The NT carb has 1 screw, an idle speed screw and 1 fuel jet.
It is the simplest of carbs to tune, not much going on inside them to monkey around with.

woodruff key fell / got worn out of drive sprocket - had to walk home about 15 blocks. then i made made a new one out of a big washer. Mixed up some 40-1 amsoil saber and proceeded to spill gas all over the bike trying to fill it up. lol.... tightened chain and rode to the motorcycle store, bought some fuel line, a fuel filter, a ratio rite cup and most importantly a replacement NGK plug boot for my friends bike - cause' the stock ones are crap and keep breaking.

put the whole motor,cables,head,cylinder,carb, exhaust ect, back on after freeing up the engaged clutch issue. and making a temporary mount and stud.

Fired right up I was pretty stoked I knew chain was thrashed from when it got twisted and rode it around the block almost. New tire, and chain, and clutch arm cover to be ordered. Just happy it ran.

Wanted to insulate my exhaust pipe because it burned a hole in my pants leg the other day. So I go to Auto Zone, the only exhaust wrap they have is a 20ft roll for $50. Way too much. So we go visit my wife's sister and her husband, and he seems to think we may be able to find something at Ace hardware. We end up in the stove repair aisle looking at stove gasket. They have a roll that's almost the same diameter as my exhaust pipe (ezm flex pipe, btw) and I'm thinking I can get it wet and stretch it over the pipe. So I get home, throw the stove gasket in a bucket of water, and take my dogs out. Go get my tools, and start working on it. Took some finagling and some elbow grease, but eventually I got it on. I left about an inch uncovered between the header and the flex pipe, so the exhaust can still breathe some, and put the exhaust back on. I then hooked my crankcase breather tube back to the carb's pcv (positive crankcase ventilation) inlet and took her for a spin to dry the wet stove gasket a bit so my pipe won't rust. Bike seemed to run smoother after hooking the pcv tube back up. Didn't go too far, so its hard to say for sure, but I'll know for sure definitely after I drive to work in the morning.

This morning, I installed two missing screws from my pull start. Then I started up and rode 6 miles to work this morning, then back this evening. Pure joy of riding without incident, like two 25-minute amusement rides. What a wonderful way to start and end a working day.After years of riding to work, I have my route down to a science, and know exactly when to hop on and off the sidewalk. I also get a 30-second headstart at three different traffic lights, so the cagers can't catch up and crowd me in.

I would check your float height,,sounds like too much fuel if your fouling plugs,,also may be coil or mag getting weak after it gets warm,,check that the jet is tight also make sure air filter and choke flap are ok.Might want to start your own thread on this one

Good times ...

Today's plan includes wiring the ignition back up on the cruiser, and taking it for a spin. At this point I can't properly test the ignition as my multimeter's fuse is dead. I'm tryng to track down a new $2 fuse (250mw250A), instead of having to pay $25+ for a new multimeter, but so far the closest I've found is double the rating (500mw250A). 'The Source' stores around here seem to be pulling thier small parts areas out, so I'm going to have to hunt for a local stores that fills that niche I guess.

It's supposed to be a beautiful day, so a trip out to the coffee shop or something definately has to happen this afternoon. Black cars might look better in the shade, but chromed MABs look prettier in the sunshine.

Put some air in my tires, adjusted my throttle cable (again, lol) and changed the oil. Started her up and she purred like a lioness for me.

Took the cruiser out for a while. It runs pretty nicely, and has nice pull when you hit the 'sweet spot' in the throttle. A new problem's popped up, of course. I'll be cruising along at about 1/3rd throttle, and you can hear the engine start slowing down until it stalls out. There's little or no positive throttle response at this point. Opening the gas cap had no effect, nor did holding the primer on the float down. After a short time, it fires right up again and powers up to speed smoothly, but a few minutes later the same slow down and eventual stall out will occur. Scratching my head a bit on this one.
