fuel treatment to fix stuck float?

Post by buddy »

Is there a good fuel treatment for a 2 stroke? I cleaned out the carb my new rattler 110, but I didn't think to disassemble the float valve and clean it out. Now, I can tell the float is not refilling fast enough. It feels like it empties the float bowl then bogs down. Wait a few seconds with the throttle up and then throttle down again and it surges with power.

Is there a good fuel additive that you think might clean that float valve out without having to take the carb back out???? Please tell me what I want to hear.
:P

Thanks in advance, Scott

Seafoam & Techron will both work. It's possible the issue is with the fuel valve or vacuum line, though. Good idea to check them also.

Thank you. I'll check the vacuum lines. I bought seafoam last night, so I'll pull that in there too. If it still has problems, I'll put the carb back out and do a more thorough cleaning on it.

I cleaned out the float valve in the carb and also added sea foam. I only ran it for ten minutes or so, but the problem did not go away.

The next thing I'll do is replace the fuel filter. It looks pretty dirty. Hope that works.

If your analysis is correct, maybe your float level is off.... but more likely, the low speed mixture is out of adjustment. Seems that the adjustment screw (at least on my rattler)... well... rattles loose. The adjustment screw is the brass flathead screw on the side of the carb. You can barely see it if it is installed and you cannot adjust it without removing the underseat storage container. you can drill a hole in the storage container to make adjustments without tearing your bike apart.

Drill the hole. On my 110 I need to make that adjustment with the extreme temperature changes too. 40's in the spring and fall, 90's in the summer. They both need a different adjustment. Taking the bucket out all the time got to be more than annoying.

If you simply get a properly sized screwdriver then there's no need to drill a hole or remove the seat. Just sayin'.

My analysis was not correct, so I thought I'd post an update.

After cleaning the carb a couple of times, I had the same bogging down problem. A neighbor that has experience with 2T bikes thought the symptom was related to a reed valve problem. I removed the reed valve and it looked fine to me, but to be sure I took the reed valve to a scooter mechanic. He said it looked fine.

The only problem was that the gasket for the reed cage had a tear in it. Well I put blue gasket goopy stuff around the problem area as well as all around the gasket to be safe. Put it back together with a new spark plug and it runs great now.

So perhaps it was sucking air at the torn gasket? I do not know, but I'm certainly happy it's running now.

Nice work. Intake and exhaust leaks will cause odd problems. Glad to see you got fixed.
