87 spree trouble after cold start

[aanguia1]

Just got my spree this Monday and I'm loving it, but one thing that does bother me and idk if this is normal. every morning (4am) about to leave to work, I kick start it, starts on the first kick which is nice for a 80s scooter! Well when I try to leave I sit and twist the throttle it goes a few feet then wants to shut off so I let go of the throttle and it goes back on idle.... I do this till it finally goes up to speed but its only on cold starts or when its sitting for 8+ hours....

Any ideas? Owner said to come on this forum and so far its a great community based on what I've been reading...

I'm good with direct injected motors but 49ccs are a totally different planet compared to what I'm used to seeing...

Thanks for reading I appreciate it

I would suspect the by starter or or that passage that supplies the circuit with fuel is clogged up. First pull the carb and clean it well paying close attention to the small orifice in the float blowl. They clog easy and cause trouble. Also check check the entire intake tract. If the air hose or air box are leaking it may be an issue. Or even a rotten air filter element could cause the lean issue you speak of. There is a test to see if the by starter is working properly in the manual. You apply air to the by starter air hole on the intake side if the carb, the manual will state at what point air passes through. That test will tell you if the by bystarter is protruding enough or not. Most likely you will find your solution in a carb cleaning and or a loose air hose or something like that

Thanks I'm gonna try these methods, any other ideas that miight be the culprit anyone

Hate to say this but I'm pretty scared of taking this scooter apart, I'm good with cars but little motors like these I don't know anything I don't even know what the carb is or how to take it apart lol

One of your ports / jets are clogged.

Scared.... please don't be scared. You can do it, and you will have a sense of accomplishment when finished. Trust me - I am dumb as it comes but I am not scared.

Get a can of carb cleaner and strap the straw on it and get after dem hoes.

There is plenty of help here if you need it. Take your time... it usually takes a person two cleanings the first time to get all the tunnels and holes clean.

I put in the throttle cable / body in backward my first time. Watch the seal to the intake. The gasket sometimes gets installed upside down.

We are here to help get you back in business my friend.

First thing: these small engines will require some warm-up time before the internal temps are up enough to fire when throttled. The introduction of cold air will cause stumble until warmed.
The fact that it starts right up indicates NO problem with bystarter.
More likely to be a clogged pilot jet according to your description....
But STILL, you should verify ALL passages and jets clear before reassembling the carb.
This takes very little time, and keeps you from repeating cleanings...
The key is using the spray-can of carb-cleaner correctly to be certain of clear jets (etc)
Hold the red (they're always red) straw firmly against all holes and tubes and jets...everything that flows gas or air.
With short blasts, observe the carb throat to see if jets are open.
WEAR SAFETY GLASSES (should have said that first...lol)
On other passages, determine where they lead, spray, and observe to verify clear.
If you can NOT see something is clear, (especially the pilot jet), then probing the hole with suitable cleaning tools is needed. I use a set of "jet files" and wires that are strictly for this purpose. They're cheap = <$20
Ultrasonic cleaners and Chem-Dip cleaners are two of the popular ways to "CLEAN" carbs.
I use Berryman's Chem Dip and lots of compressed air.
Spray-can only methods are less successful and most result in multiple cleanings.
Much care is needed to remove all parts from the carb body...ALL PARTS
It is very helpful to have a schematic of the carb when you are unfamiliar.
ANY Honda parts fiche online will suffice...
Patience and repetiton are the best for you....g'luck...

EDIT: Your problem MAY NOT be a clogged pilot. It would have not mattered being cold or hot if so.
A simple idle/air mixture screw adjustment could be the only thing wrong...just sayin'...IDK
I expect a thorough cleaning will do some good, regardless, and you should explore this for your own enlightenment.
The AIR FILTER is extremely important to proper tuning. Make sure it's there and in clean, oiled condition.(Unless that's a paper filter, IDK)

Wow this helped out a lot , haven't had the time to look into it I work 12 hrs a day (peak season) this morning I cranked it and let it idle for about 3-5 minutes. When I finally went to ride it didn't stumble much at all I took it to 15 mph then it started to bog a little.....but eventually took me to 30 mph on flat roads....

But the fact that it bogged I still think something off I think I'm gonna try the air filter first then go from there

Thanks guys I really appreciate this
