New 2410 too lean

Thanks for the forum guys. I participate in several hunting forums but need some advice...
Bought a brand new TB 2410 and it’s so lean it only runs with choke at 3/4 closed.
For years I rebuilt automotive engines and also specialized in carbs so I have a familiarity...........
Even though I shouldn’t need to I did pull the bowl looking for debris and ran a small wire through the main jet.
No help. Thinking I should return it and double my budget for an Ariens 24” deluxe...
Thoughts please!
Thanks
Dave

It would def get you a heavier duty machine (I LOVE mine) but if you decide to keep the 2410 you will need to open up the low speed jet, if that’s the case we can explain how to do it. But the deluxe is a much nicer heavier duty machine.

Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.

welcome to the forum ! if you can double the budget , go for the ariens ! the tb is not a good overall machine imho, but a micro drill bit does wonders

id return it and get another one (but if you want quality, get the ariens)


if you insist on keeping it, you need to pull the bowl and take unscrew the jet (its a flathead screw driver)

then take a drill bit (jet bits, im assuming you have them)
and then increase the size, id increase it by incruments of 2
(do this more than once if you have to, theres no need to rush)


hope this helps!

Is it the main or idle jet that needs worked over?

If you can afford double the budget why not? But contrary to others opinions the 2410 isn't a bad machine. I'm on my 3rd winter with mine, with no problems other than the emulsion tube getting blocked which caused the same issue you're having. Remove the bowl, unscrew the jet, and the tube should drop out, use a thin piece of wire to clean it. But if this is a brand new machine that shouldn't be your issue, I'd return it for another.

If it's pulsing when just running it is the idle jet which is in a plastic plug held in by the head of the throttle stop screw head, If it is pulsing under load it will be the main jet needing work, So far just opening the idle jet has worked on a few different brand 208cc engines including a 2410. I open them to .018 thousands of a inch. I do also have access to very small drills as I am a machinist.

its the main jet, you need to make it richer

this should be the same carb that you have ( from what i can tell, your engine is a honda clone)

skip to the 1min mark

see how he removes the main jet? its going to be the small one (not the long piece leave that one alone)

make that richer


then skip to the 2min mark, and follow the reinstall

(note: you do NOT need to remove the float, the jet is easy to access)

It’s surging with no load at full throttle. It won’t even idle without the choke at 3/4.....

new machines surging almost seems normal to me now. neighbors snowblower has been doing it for as long as i can remember. does it every year and it is a few years old. i also know a few people with fairly new ariens that surge also.
