Gio Mini Hummer (new) quit after 3 minutes.

Brainsquishy · 03-18-2010, 11:05 PM

Just assembled and quickly got a new Gio Hummer 110cc assembled and running at my shop today. YeeHa!
Actually its not for me (200lbs and 6'1") but my son if no one new that.

Anyway, .8L of new oil, new premium gas and I putted through the lot with him and me on it. Went up a small rise and the motor had to work a little bit then it quit, Started it up again but died after adding a tiny bit of throttle. Did that a few times, then I pushed it back into the shop.

I confirmed spark and the battery is good. However, there is about 40-50% of air volume in the gas filter. Do I need to bleed this out?

Any suggestions?

Thanks in advance.

Could be some crap stuck in the carb or tank, personally i have replaced all the stock fuel lines on my GIO quads and used a new fuel filter. If i were you i would remove the fuel line from the carb and make sure fuel is flowing smoothly out of the tank, if it is i would unbolt the carb, take the fuel bowl off and make sure all is clean inside, then reassemble and try again.

Also remember the stock spark plugs that come with these are kinda crappy, i highly suggest using a NGK CR7HSA spark plug, you can get these at Canadian Tire ( part # 018-3670-6 ), $6.99 or $7.99 for 2 of them.

Brainsquishy · 03-18-2010, 11:52 PM

Thanks for those replies guys.
I came back to the shop again tonight and started her up again several times. It starts fine and will idle away, but when I give it more than a little bit of gas (rear end lifted up and wheels spinning) it stops. Then I repeat the sequence.

Have you tried using the choke to see if that helps, if so then you probably have a restriction in the fuel delivery somewhere, as mentioned above, check fuel flow from the tank to carb, make sure the main jet isn't plugged, make sure the clip hasn't fallen off the jet needle. Keep us posted.

Hello , I had a customer with the same thing.. it ran for a while.. and then problems.. when you start it up.. sitting there it runs ok.. and then when you put it under load ... like to make it move.. it stalls... adjust your carb.. make sure it is running fast enough to start with .. and then adjust the air screw.. about 1 1/2 - 2 full turns.. and it should be ok.. like it said in the other reply .. make sure you have fuel.. make sure the fuel bowl is full.. make sure you did not pinch the fuel lines... people go overboard with these... the fuel lines are good enouigh for general uses.. especially when new.. you can do all this stuff later.. like new lines .. new NGK spark plugs.. foam air filters. etc... when the air and fuel screws are set right .. you can rev the motor when the brakes are applied ... and it will not stall out.. this is the same as if you had a load on the atv.... like a rider.. do this and then re-post the results... do nto go hairy on this problem.. this is not rocket science

TheRealWorld · 03-19-2010, 12:25 AM

I am guessing this is 90 percent a fuel problem. That air bubble in the fuel filter does not usually mean anything. Make sure fuel flows into the carb freely, and then see if it drains out of the carb through the screw drain on the bowel. As others have said, check fuel adjustments on the carb.

Good to hear from you again!

FastDoc · 03-19-2010, 12:37 AM

A fuel filter will typically not be full of gas. Like when the flight attendant tells you that even if the bag does not inflate oxygen will flow through the mask...

I've seen a kink in a fuel line do this more than once though.

Cal25 · 03-19-2010, 09:53 AM

Really sounds like a litttle trash in the main jet. If it ran fine for the first 3 minutes, the adjustments are likely fine. Just sucked a piece of crud into a jet. I bet if you pull that main jet and blast it out , it will be fine again.

Brainsquishy · 03-19-2010, 10:55 AM

Thanks guys, awesome help.

I see the adjustment screw on the right side of the carb, but I am not sure what that one is for. Is it the air adjustment screw or fuel?
Where is the other screw located?

I will frig with the adjustment for a bit, then start removing and cleaning. The lines all seem to be free of kinks etc. I will confirm fuel flow and bowl.

Am I suppose to unscrew the cap at the top of the carb to clean it out? I have compressed air here, should I blow that out?

(and thanks for the hello, I really never left, even after I bought my KLR650. This is a very good forum with good people. Nice to be a part of something the good guys own. There many people in the business world that can't seem to connect with people on this level. ) :wink:

TheRealWorld · 03-19-2010, 11:19 AM

Don't go after it with a compressor. The cap on the top is not where you need to go at this time. Someone of these talented guys will probably post a pic for you on those screws. The one that drains the bowel is near the base of the carb, and it is tight off. Opening it a little will allow fuel to flow easily in a small stream, If everything is OK.

Cool, I will get on this and post back for all the other newbs.

You've received some good advice here from some smart folks.

In my experience with the 110 motors, it is very choke position sensitive. You could have a fuel blockage somewhere, but as waynev pointed out check the choke setting and play with this.

The stock carbs have an idle screw and an air screw, I've never really found the air screw to do much. I would be careful it doesn't fall out though, as I've seen this happen on a couple of these.

waynev · 03-19-2010, 05:04 PM

Here a few pics to help you along, this carb is from my 110cc GIO T1, it should be the same as yours on the mini beast, or very close to it.

In this pic you will see the BLACK arrow pointing to the idle screw, this will change the idle RPM of your engine, turning it in is faster and out is slower, next is the RED arrow, that is your air/fuel screw, since it is on the engine side of the slide it will control fuel, turning it out will be richer and in will be leaner ( when and if the air/fuel screw is on the air filter side of the slide it will then control air, so out would be leaner and in would be richer ).

Ok in this next pic is the other side of the carb, the GREEN arrow is pointing at the fuel bowl drain screw, turning this out will let the fuel in the bowl drain thru that tube on the bottom of the fuel bowl ( make sure the fuel is off or main fuel line has been disconnected as it will keep draining until the gas tank and fuel bowl is dry ). The YELLOW arrow is pointing at the choke lever, i know on all my GIO quads moving the lever all the way up is full choke. The BLUE arrow is pointing at 1 of the 2 screws that is used to hold the fuel bowl on, you will have to remove this to get to your main and pilot jets.

Hope these pics help you out.

Brainsquishy · 03-19-2010, 11:13 PM

OK, nice on the pics weynev!

I complete the NIGHTMARE of removing the carb of the engine. My hands are in no way small enough to properly work on this thing. They are quite sore at this time, however the job got done.
(only swore 116 times)

The bowl drain screw is quite seized in place. It will not move at all. Messed up the slot on it trying to open it. No biggy.

I took a couple of small pieces of junk out of the main body and checked all the interior parts.

Its back on the bike. While it was off I turned out the fuel screw a half turn, which is to the left of the idle screw. I turned out the idle screw 1.5 turns.

While doing this fooling around, my battery ground wire cooked and nearly caught fire. I had a 2 amp charger on the battery at the time. (electronic charger) What's up with that! and with all that fuel around. I will now recommend not to charge a battery while screwing with fuel!

Anyway, when I got all the cable and crap hooked back up, I started it. It nearly took off on me! I am going to adjust the idle screw in and try again now that everyone has gone to bed.
