8N Carburetors

I would close the valve at the glass strainer; then pull the plug on the bottom of the float bowl and drain what is in there. replace the plug

then run both adjustment screws in all the way--don't overtighen the brass--and back out a turn and a half. this ought to be close enough to get it to start. then adjust like the other posts suggest.

if this cures it put purging gas tank on your spring "to do list"

happy holidays

Meanwhile, that still doesn't get you started wit a mis-adjusted carburator. This is what I'd do.

Set both jet adjusts to 1 turn out.

About 1/2 throttle, whiff of eather, and get it running. After warmed up, throttle down to about idle, and adjust idle mixture for max RPM's. Throttle down as slow as you dare and max idle mixture again. Then set idle speed to 400-450 or even 500, what ever makes you confortable. Then max idle mixture again.

Main jet/power jet. usually set under load, like plowing or going up a really steep hill, turn out 1/8 turn at a time until it takes the throttle smoothly. Then check your sparkplugs. Are they black and sootie (too rich), clean an white, (to lean), light tan/grey just about right.

If you turn eather jet more than 2 full turns, you are probably mis-adjusted or got other problems..... ....Dell

I had a problem a little back that the tractor wouldn't hardly fire even though it seemed to have good spark. It wasn't getting fuel. I Couldn't get it to turn over fast enough to fire. Had to pull it down the road to start it. After that it started fine again. Carb problem seemed to have caused all this. Problem solved- but your carb has to be operational first.
