SOURCE: Gas leaking from bottom of carb on 90cc ATV

yes there is a tube that goes on it. It hangs straight down about an inch or two past the botom of the 4 wheelers frame. It is for a overflow of gas, which is usally caused by either dirt in the carb holding the float to high and allowing the gas to just run straight thru and out the bottom of the carb or a bent or maladjusted float setting. But since you said it just started, i would suggest this. I have fixed many and many bikes by simply removing the carb bottom and cleaning it with carb cleaner. It onlty takes a small piece of dirt between the float needle to keep the needle from making a good seat in the carb. Clean it well Please be carefull and keep the carb well away from your face as to not get any blowback of cleaner in your eyes(IT BURNS) This should fix your probblem

Let me know

SOURCE: Won't idle without choke

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

SOURCE: I have a 03 Yamaha 660 raptor one of the carbs

Did you reset (adjust)the float inthe float chamber to tht carburator which is leaking ?
You will probabley have to adjust tht float to stop from overflowing in other words we call it flooding.
Check the float pin of wear at the tip.
Hope this helps!

Suzuki jr80 takes too long for rpm to get back down to idle , after throttle is released. wasnt run for couple yrs. completely disassembled carb and cleaned. it starts 1-2kicks.not setting correctly?

Hi, Troy and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

1987 Suzuki samurai take 30 minutes to start in the morning only the it start OK for the day seems like it not getting gas in the morning only

the G13 or G16 engine, and 1987 year was carbs, not EFI.
so if it has carb , you need to say so.

if it starts fast with test fuel (spray)
then your choke is dead.
ever adjust a choke before.

Where is fuel filter vs 1400 Intruder

FIRST DO NOT SMOKE while working with gasoline I can not express this enough! There are two filters on my 2000 VS 1400 GLP there both located in the inlet on the carb sink needle. You'll need a repair manual they can be found on ebay about $20 + shipping. The seat has to be removed to get to the gas tank bolts (10mm socket) rear seat first then the front then the gas tank bolts. Lift the gas tank you will see the two fuel line's and the petcock turn the petcock flat screw like till its horizontal then remove the fuel lines at the gas tank they can be left in place but do drain them. Air box to carburetor boot's are next. The side cover's need to be removed too. You'l have to remove the carbs one at a time. Before you do this count the number of threads left on the throttle cable where it connects to the throttle. This is critical for carburetor synchronization. Remove the choke cables. Front choke cable is held in place by a phillips head screw remove it the choke assembly should lift off the plunger that feeds extra fuel in the intake stream. The rear threads into the body this is plastic be careful they damage easly. Remove the float bowel drain screw prepare for fuel draining there should be a drain tube on the bottom of the float bowel place the tube into a used soda bottle if it's clean you could drain whats in the bottle into the gas tank. Counter clock wise turn the drain screw out but do not remove it when you see gas in the soda bottle & it stops move on. Once there drain'd turn over the carb remove the 4 phillips head screws you will see the floats they will have to be removed by removing the pin going thew the float towers be very carefull these carb bodys are made from pot metal very brittle & break easily. Once there out of the way you will see the sink needle assembly held in place by another phillips screw remove it the sink needle needs to removed can be done with needle nose pliers then the filter can be seen remove it very carefully either replace or spray it carb cleaner any auto part's store sell it. in the opposite direction of flow that should clean it. Reverse assembly. I hope this helps you fix your own bike a few more suggestion use a big old bathroom towel to work on your carb, parts don't roll away into never never land. Take your time and pictures for reference's if needed.

No floats in chainsaw carbs. Severly flooded most common start problem with chainsaws. Read and follow the start procedure in your manual. Don't use choke on flooded engine (may set fast idle, set then turn off)!
