New 50cc retro peace sport stalling issues By chacoscootin (Read 3,125 times)

Hello! I am brand new to scooters so please be kind! 3 days ago I purchased a brand new 2012 (only 1 mile on it) Bash Peace Retro scooter. I know, already probably a chinese piece of crap. Well I drove it home, it was running great. Took it out to get fuel (premium) filled it up drove it home and the problems began. After cruising at high speeds and throttling down to lower speeds it stalls, and engine completely dies. If I am going quick..30mph or so and stop at a stop sign it stalls when switching to lower speeds again. I have popped the seat off and began slowly adjusting the carb fuel adjustment screw a half a turn at a time to adjust the idle speed. This is what I was told to do after calling the scooter shop. I've only put about 25 miles on the thing. Why is a brand new scooter stalling? The store I purchased it from said they did all the tune ups prior to handing it over to me. I would like to take it back to the store however I don't think it's going to get there without stalling. Any ideas?

I've attached a photo of the screw I was told to adjust slowly while listening to the idle speed. This is what the place told me to do over the phone that I bought it from. Does any of this make sense? Sorry if I am a bit novice at this.

Yep that's the idle adjustment screw. I put the bike on the centerstand and adjust it until the rear wheel just barely moves:

The A/F screw is here, but I'd leave that alone until you get the idle ruled out:

A slow idle will make a scooter stall when the bike gets down to almost stopping. If you are stalling as soon as you close the throttle it's something different. That could be your valves need adjusting or a vacuum leak. So try the idle adjustment and see what it does.

listen to him ^^^^^
he's the boss
try the idle screw, then can try the a/f screw
then adjust the valves

oh and HI lol
chinese scooters are the luck of the draw
mine has never given me a real prob
other have tons of probs
your sound like a easy fix
hope so

Thanks everyone, the sun just went down and I don't have a garage..so I'm going to get out there in the morning and give it a try again. I'll let you know how it goes. If by chance it's not the Idle Speed Adjustment are there any tips to tweeking the A/F screw?

yeppers there is
theres a whole 'page' that the guys here have, that spell out exactly how to do it, i dont have that so we will see if they post it

one prob might be,
the EPA cracked down on chinese scooters
alot of the newer ones have almost tamper proof
a/f screws, but again these guys know a way around it


oh and another woman---love it!!!!!!!

I am betting since it is a 2012 scoot the Fuel Ratio Mixture has a plug on it. They set the carbs very lean to pass EMISSION tests and it might need a little more fuel. But first try the IDLE Speed Screw turn it CLOCKWISE just a little it does not take much like 1/16 of an inch will raise the idle. Set the IDLE AFTER the SCOOT is nice and warm not when cold. Bring up the IDLE until the Back wheel starts to spin THEN Turn the IDLE SPEED COUNTER CLOCKWISE just a hair SQUEEZE the brake to stop the wheel from spinning and let go and see if it still starts to spin. YOU WANT to set the IDLE JUST so the WHEEL DOES not turn or VERY VERY SLOWLY.

If that does not solve the problem then I am afraid you will have to adjust the FUEL RATIO MIXTURE and or VALVES.
If the FUEL RATIO SCREW has a PLUG then there are 2 choices.
1. Get an aftermarket carb they come with the FUEL RATIO SCREW NOT PLUGGED so you can adjust the MIXTURE
2. Drill out the FUEL RATIO PLUG to get at the Screw behind the plug.

So Look on the side of the LEFT SIDE OF THE CARB the 2nd picture rich put up and see if the FUEL RATIO SCREW is PLUGGED with a GOLD plug or IT has a SLOT on it for a screwdriver.

Ok guys, been fiddling with the idle screw today. I thought I had it all set and things were good to go. I put it on the kick stand and adjusted it until the rear wheel barely moved at idle (which seems like a hard task, it always wants to move or not move but not barely move) Took it out for a spin and trouble again. It's rumbling occasionally when I turn it on, like it is either coughing for fuel or air and then stalls out. The shop I bought it from is a good 10 miles down the road and I am having difficulty finding a way to get it back there without riding it (ex Truck) but I just want to be able to ride the darn thing. Is the idle screw that finicky? Is it supposed to be super temperamental and hard to find just the right spot?
