O.K..... did this, as you said they would be these jets were blocked solid. Cleaned them out with oxy acetylene tip cleaner set, carb cleaner and compressed air,- problem still persists. Float levels are 22mm, is this correct?glidercoach wrote:Make sure you remove the smaller jet behind the main jet. Clear it out with a small wire from a wire brush, then carb cleaner... A needle is too big to go through it. I just had this problem and missed the smaller jet. The bike runs perfect now! Thanks to all the guys on this forum who gave me support for my ride!

Yeah, that's pretty close. The manual says 21mm +/-2mm, so your within tolerances. I take it youv tried running it with the fuel tap on prime in case the vacum diaphram in the tap isn't working well.
Might be worth putting a compression tester on it just so we can rule it out. Your looking for between 107 - 164psi depending on how fresh the engine is.

Thanks for that Scotta. The problem is definitely not with the fuel tap as am running it {or attempting to} through a funnel tube. Thanks for the compression figures, will check this out. As mentioned in my initial post it will continue to run with ether {start ya bastard} sprayed into the carbs but since this presumably is more easily combustable than petrol I guess you could be right about the compression. P.S., as an added precaution I reckon I might soak the carbs in white vinegar for a few days just in case there's calcium deposits lurking somewhere innaccessable.

To be honest I have never tried the vinegar method myself but I know others who have done so with success. It works similarly to CLR but is not so aggressive. Drop an egg into white vinegar to see what this will do to calcium. Disolving calcium seems to be the vinegars one trick so you don't have to worry too much what else it is eating while your carb is marinating in it, unlike the CLR which works a lot quicker but can do things you don't want it to do if you're not quick/careful enough.
