How can I tell If I have a clogged float chamber needle valve and is there any way to clear it without dismantling and overhauling the carburettor

Just made a reply to your other post on same subject. The clog if not plastic or metal should clean up with strong fuel solvents. Some metal dirt debris can be removed with a pencil magnet. I might even use PB (power blaster) with a spray nozze like used for cans of carb cleaner and BTW the brand GUMOUT's (others too no doubt) nozzle (spray tip and hose) fits the PB cans I have such that the little hose can be used instead of just a poorly directed spray. Good luck,
T
Ps: Trick- AYOR!!!! Depending on what exactly is wrong if you are pretty sure it's a needle valve problem is to tap at the right spot with a PLASTIC hammer. Again - fire hazzard and you could break/damage carb metal so AYOR!

If that type carb has a float bowl window in it you can observe the float to see if it is sticking or sinking. If it is sinking due to obsorbing fuel into itself then the float will have to be replaced. Carbs of that era are not so bad to work on, the kits are cheap and it only takes a couple of hours to R & R. The kit may not have a float included so be prepared to order it seperately. The kit instructions are usually easy to follow, just read them thoroughly and have a good understanding of what they are saying before you begin. It's also a good idea to have compressed air available to blow out the parts after you dip them in carb bath.
Assuming you don't have compressed air, a carb bath can (available at auto store), or the knowledge of tools and supplies needed to work on it, and you still want to try and solve this on your own with a can of carb cleaner...
Run engine until it reaches normal temp, then remove air cleaner, thumb the accelerator valve assembly from full throttle to idle while shooting the fuel jets with a heavy stream of carb cleaner. This will kill the engine so prevent it by throttling up the assembly. You may just shake loose any clog.
Last but not recommended is to shut down the motor, let cool. Unscrew the fuel line to the carb (if there is an inline fuel filter be very carefull to keep track of all the parts and order of re-assembly, it's spring loaded if it exists)and shoot very short bursts of air into the chamber where the needle and seat are located. This could solve the problem, but depending on a few factors could perminently unseat the needle from the seat requiring you to remove the top of the housing and manually re-set the needle onto it's seat. The good thing here is if you have to do that then you will KNOW if that was the problem and it will be fixed. If it wasn't the issue then you would probably have to rebuild the carb anyway and be done with it.
Good luck !!
