Setting the throttle idle on a Tilloton Carburetor

This video I show how to properly set the throttle shutter and explain why.

Hi, I have a single rotor Wankel powered glider with a Tillotson carb. Above 7000' and around 3/4 throttle I have coughing and hesitation like the mixture is too rich. The engine runs much better at 1/2 throttle and somewhat better at full throttle. From your video it looks like the first adjustment you make, setting the blade, is the only control I have for mixture control. I will try opening the blade a bit and see if things get better. Thank you for your video, 2 thumbs up even though I am not a kart driver.

Have a HR44A Tillotson Carb. Starts but wants to go way too fast like a jet out of hell.. Adj (fast and slow) screws don't slow it down. The throttle 'doors' are closed... do have an air leak somewhere ????

How do you compare this carb to a mikuni flat slide or square slide carb? Better? worse? equal?

[@jamesbarlow6104]

What kind of mods if any or adjustments do i need to do to the tillotson to run E85 on a stock HL-334WX?

[@castellolouis]

Hi man, i have a Tilloton HL-166B in my kart with Comer 80 engine. When the fuel is sprayed directly into the cylinder engine starts. But when I try to boot normally through the carburetor and the engine draws in gasoline. I headed it cleaned but still it does not work. Could you advise me what is the problem? Possibly replace what? thx

dear sir,my engine work idle until choke shutter is completely close and when I start to opening the choke shutter,engine accelerate with very high rpm for few second and falls,I don't know what is the problem!

Tillotson carbs are not meant to idle in the sense that if it is idling it will bog and possibly flood in the low end around turns. This is true with racing karts as this is what we tend to run. It is a simplistic design, but tuning the high/low speed jets can be tricky and takes running the kart (on the track) to get right. And no single setting will work best for each different carb. We have found that what may work for one carb most likely will only be a baseline for another. While I am still new to kart racing, it is a great carb to run for this application.

towboater781 yo so im new to karting (i mean at least with our own kart etc) and yea you mean i cant let it idle? Like it’ll mess up the engine?

hey i got a tillotson 320 on a snorunner. my sled came w no muffler so i bought and installed one. it ran fine without it but now wont even start. i assume its a carb issue so i tried adjusting but dont know what im doing. it only has two adjustments a H and L where do i start turn both right and back out or vice versa. any help would be appreciated

hey to start adjusting a carburetor turn low needle in until it seats turn out 1.5 turns seat the high needle in to seat it then out 1.75 turns start engine and get it to idle if you turn it until the motor sounds like it plains up smoothly then the high needle run the motor at full throttle under load (spinning the track) turn in or out until the engine plains out or runs smooth and if your carburetor is in good working order you should be perfect never adjust carburetor at idle on high needle it will never work
