Recon Won’t Idle

Hi all,

Still working to get my new-to-me ‘98 recon ready to roll. Today I took the carb off and tore it down. The inside of this thing was basically black. Thick coating of something in the bowl. I soaked in gas and scraped all I could out. Pulled the jets out, both were plugged solid. Freed up the main jet pretty easily, and eventually got some light to shine through the pilot jet with help from a sewing needle and a soak in gas. Once I was fairly sure jets were clean, I buttoned it all back up and reinstalled. When I turned fuel on, gas poured from the drain valve on the bottom of the bowl. I made sure it was very well closed but it continued to leak. I then decided I’d kink up the drain hose with a zip tie. No bueno - gas then came into the air box. I took out the fuel tank, made sure fuel ran through the hose and it seems to. Now it will start if you crack open the throttle a hair, and runs fine while giving it throttle. But if you let off the throttle, it dies. It also seemed to die while running sometimes. And after it got hot it was kinda difficult to start.

Is it safe to say a carb rebuild kit will resolve this? I’m stumped.

Thanks in advance.

It's flooding out and won't idle. I would get a gallon of carburetor soak from the auto parts (about $30) and let it sit in it overnight after taking it apart. That's not entirely necessary but one thing that is, you blow through EVERY hole to make sure it's unobstructed. Air works but I prefer wd40 so you can see the liquid come out the other side for verification. Starting fluid and that sort of stuff works well also but make sure you have some glasses on because if it splashes in your eye, it burns. (It's not like I was looking through the other side to see if it was going to come out., lol)
I have rebuilt many a carburetor successfully without any parts but getting a new kit is always a plus, can't beat new gaskets.

it still sounds to me like you have a dirty carb
if it was as bad as you say, I doubt soaking it in anything will clean it really good
sounds to me like its going to need a rebuild kit for sure, and all hard parts to maybe be in a ultra sonic cleaner a while to get things to where they should be

you can also, try removing any soft parts(effected by heat) and boil the carb/parts in lemon juice,, its been known to work better than soaking in carb cleaner!

ethanol fuel over time forms a varnish coating to all parts and passages and it seldom comes off from soaking, its just too hard already to come off that way, , so, replacing parts that you can with a rebuild kit will sure help, but it won;t help in other places
so, to me, its either boil or a ultrasonic cleaner to get carb to where it needs to be, when there this bad!
