Idling faster uphill? stalls going downhill Tue, 29 March 2005 02:30 Go to next message
Hey guys, after trying to tune my TA23 i found that it idles much higher when it is heading up hill, but when heading down hill it will stop. I set the idle to run at 800rpm when on level ground but soon as the slope changes so does the idle speed.

I am guessing this is the float level(what else can u suggest?).

Can some 1 plese tell me whether the float level is to high or to low and how i can adjust it.

Regards, Jeff

Re: Float level adjustment on 2t Tue, 29 March 2005 04:40 Go to previous messageGo to next message
Hi,

I'm assuming it's a stock 2T engine with the stock carbie?

If so....

Float Level (raised position) is 3.5mm
Float Level (lowered postion) is 1.2mm

Raised Position
Hold the air-horn upside down and allow the float to hang down by its own weight. Check the gap between the float tip and the air horn. Standard gap is 3.5mm. Adjust this gap by bending the centre metal lip.

Lowered Position
Lift up the float and check the gap between the needle valve bushing pin and the float lip. Standard gap is 1.2mm. Adjust this gap by bending the outer metal lips.

Metal Lips
When looking at your float you will see two longish rods with holes in the middle. The float is attached to the air horn via these rods. Just inside these rods you'll see two metal lips, and a single metal lip in the middle. The inside, single lip is the one you adjust for "raised position", and the one's on either side of this are for adjusting the "lowered position".

Hope that helps

River, cheers for the info. it did help.
It helped me to find out that it wasnt the float level that is making it idle faster facing uphill.
Float level is correct but sill idles faster uphill and stalls heading downhill.

Any ideas anyone?

I dont beleive they are stuck, by looking at them i can see that they are worn but i cant tell if they are sticking. The spring inside the needle with the little pin all still seams to work fine. I guess i can replace the needle and see wat happens.
