It doesn't make sense- there is something more than this. With the set-up You have, the bike is supposed to be running very lean. In the same moment You are telling us the spark plug is black and covered in carbon,. This is an indication of very rich running. The main jet controls 3/4-full trottle. The way you are telling- Your problem is around 1/8- 1/4 trottle- like there is a problem with the jet needle or with the emulsion tube. Going to 150 main jet is way too much. If You are keeping the stock air filter may be You should go 135-137.5. But this will not cause the bike to die.
Make sure the float is not getting stuck. Make sure You connected the hoses correct. Take the carb. apart and make sure all the parts are in the right place. It sounds like You pulled out the pilot jet and did not put it back.
I wish I can be more helpful, but everything is just an educated guess.
Good luck!

Reply #32 - 08/06/05 at 00:28:16 I am going to put everything back as was, once I get a main jet washer, and check that I haven't disturbed the needle tube when putting jet in without the washer, and then start again also doing the white spacer jobby. Never touched the pilot jet.

if your plug is charred and wet, you got too much fuel going into your bike that happened to me when i first put the amal on. Like i said in a previous post i hooked up the fuel lines before connecting the throttle cable so while connecting the throttle cable i was pooring gas in. Couldn't figure out what i had done wrong till i changed the plug. started right up after that . no problems since. just haven't had a chance to fine tune yet.

This is a mis-nomer (sp). Unless your carb has the feature of an accelerator pump, you will not flood your engine by moving the throttle linkage....ever. Gas only enters the engine by venturi action when air is drawn through the carb....

....just think how flooded all those bikes in the showroom would be after a day filled with kids and newbies cranking on the throttles and going "vvrrooomm". Ever seen a sign on a bike that says, "Do not turn throttle"?

My guess is that you got gas in there or blackened the plug some other way, and simply fixed the condition with the installation of the new carb.

How does a needle jet "stick proud" inside the carb? What does that mean?

Your needle has a clip? I really don't have to explain that one to you. You know

Main jet has a washer, yes....

Remember the spec sheet in the Technical Corner? Why would you think that you could put a #150 main into a carb that has completely different guts then the standard US carb? A #150 is 2 sizes above stock for our carbs...therefore a #135 might have been more appropriate for you....

the needle jet (#10 on the carb breakdown drawing) was above the profile of the "tunnel" as if it had been pushed up from the bottom, possibly because i fitted jet with no washer.

Forgot that the jet sizes you talk about were for usa and not uk..ooops Embarrassed

To stand proud means to go beyond the surface. In other words, the opposite of flush.

Notches on the needle... that sounds like a DJ needle - certainly not the same stock needle we get in the U.S. anyway. You can move the clip one notch to accomplish the same as the white spacer mod. At least you can with the DJ needle and the notch spacing it has. Just hold the spacer up to the needle to see what that would do. That's how I did it on mine since I'd already wasted the cash on the DJ kit.

Well, actually that drawing is a little strange. Normally the level is measured from a point inline with the edge of bowl gasket surface, not like shown.

A good rule of thumb is that the center line of the floats are parallel with the float bowl flange.....whatever the distance.

If you check them with the carb installed, just push up Gently to close the float needle and check.

Hint - usually the floats are stained/tarnished at about the float line too.
