My elite is really cold blooded, when it's warm out it starts fine but when it reaches below 50 it will start but it's hard to keep running, would adjusting the carburetor help? This bike has 1900 original miles and has never been to the shop as far as I know.
Which screw on the carb adjusts the air/ratio, I had the cover off yesterday and I seen 2.

If your carb has two screws on the left side, the one on the center of the carb is to adjust your idle(Clockwise to Raise the Idle Counter Clockiwise to Lower the Idle). Now the other screw : A. If it is to the RIGHT near the AIR INTAKE side then that is a AIR RATIO SCREW(Clockwise RICHENS it Counter Clockwise LEANS it). B. If it is to the LEFT near the INTAKE MANIFOLD side then that is a FUEL RATIO SCREW(Clockwise LEANS it Counter Clockwise Richens it). Alleyoop   |

Awesome thanks for the info, next week when I install my new HP coil and cdi I will check it out. What would cause it not to start good on a cold day? Would it be to rich or lean when the choke is on?
And how far should the adjustment screw be out? (I know on the gy6 50s they say 3 turns max)

There is no set adjustments because the temperatures effect the settings, in cold weather the motors need more fuel and in hot weather the motors need less fuel.
2 1/2 turns out is a good start then you can fine tune it to get the HIGHEST IDLE then adjust your idle down using the IDLE SPEED SCREW.

The screw on the carb is restricted you can only move it from about a noon to 3 position (maybe 1/2 turn)
Should I go richer or leaner since its hard to start when cold? I already know the idle is way to low even when it's warm so I know I need to adjust that also. But I am going to do both in the morning when it's colder here it's been in the mid 40s

There is also a hotter plug available for this bike (CR6HS) would that make a difference?

How is the screw restricted if you can move it 1/4 of a turn? Are you turning it CLOCKWISE and it will only turn a little bit MAYBE it is all the way in.
Also make sure the Air Filter is on without an Air Filter it will suck in to much air and not enough fuel.
Help me out which type of carb do you have like the 1 in the 1st picture(SLIDER TYPE) or the like the 1 in the 2nd picture(CVK TYPE).

The carb looks like the one in the top picture except mine don't have the oil input on it my elite is a 4 stroke.
There is a plastic piece that prevents the screw from being turned more then maybe a 1/4 turn either way. Is there a larger carb available for this bike? I know the elite 80 don't have a lot of upgrade options

This issue is solved, I went out this morning about 3 when it was 30 degrees and I richened up the carb and turned the idle up just a bit and it fired up like a champ

Great, good job, the motors should start with 1 or 2 short hits of the start button otherwise you know something is going south on your, Valves need adjusting, temps are causing fuel ratio mixture problems and the carb needs a tweaking or there is an air leak someplace causing fuel mixture problems are some of the more common causes other than electrical.

Well I'm back at it again. Thought I had this thing figured out but today I went out and once again she won't start, the temp is 35 and it will start for a sec then die. I can't touch the throttle either or it won't start at all.
There's a hotter plug available for this would that help at all

Temps are low so it needs more fuel, richen it up feed it more fuel. That is why it will not take any throttle if you open the throttle a little it is letting in more air.

I have the carburetor turned as far as the screw will let me turn it. On the screw there are two tabs that only allow it to turn so far either way.
Tomorrow I will have to take a picture and post it so you can see what I mean. I have seen this kind of screw on homelite brand weed eater carbs.
Would a plug with a hotter range make any difference? In the manual it says to use a CR6HS for operating temperatures of 45 and below instead of the standard CR7HS.

I just found a site online to download almost every service manual for scooters. The service manual says that the carburetor has an air screw stop that can be removed for better adjustment. Here is the website for the service manual if anyone else needs one. Www.motorscooterguide.net/downloads/downloads.html |

This problem has been solved permanently.
What I did was use needle nose pliers to break off the cap that limits how far you can turn the mixture screw.
Then I took the mixture screw completely out of the carb, put a small piece of electrical tape around it (so I didn't grove the jet) and I put it in a vise (gently) and used a hacksaw blade to cut a groove in the top so I could use a flat screwdriver on it.
I put the screw back in and turned it out 1 turn (normally 2 to 2 1/2) and now my scoot will fire up and run even at 10 degrees with no issue, just start it and let it idle, of course once you get it running the idle might need reset a little.
So for those of you that own a Honda Elite CH80 and have the same issue this is the way to fix it without taking it to a dealer.
(I would have rather done this with a dremel tool but didn't have one)
