But after it sits for 10 or 12 hours. I work 12 hour shifts and I have to choke her for a few minutes or it won't stay running. Is 12 hours long enough to be considered a cold start? Thanks in advance.Well I don't know if there are any differences in choke. when I had my CRE 450 I had to choke it before I left for work and after I was coming home. ,

Harley wont start with choke on,but can start it with choke off


Hi Cully, if you have a carburator the usual suspects are:
1. Damaged or restricted fuel tank venting system (gas cap).
2. Inlet system air leak.
3. Vacuum piston malfunction.
4. Accelerator pump leaking or no output.
5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.
8. Plugged jets or passages.
9. Worn or damaged needle or needle jet.
10. Enrichner valve not seated or leaking.
Good luck

Everyday when i leave my gilera runner vx i have to let it warm up as if i try drive straight away it bogs and cuts out what is the problem?


The choke maybe cutiing out too soon or it is the air temperature that is cool.
Let it warm up for a few minutes before riding off.

04 yz 450 backfires and is hard to start when is cold runs better with choke on


Runs better with choke means the mixture is lean,
Has the exhaust been changed.?
Did this problem just begin.?
Check for air leaks on intake manifold.
Clean carb.
Check valve clearances
raise the needle jet one notch
one size up in the main jet.

check one item at a time, and write notes about jetting changes.and improvements
I also run Moreys upper cylnder lube, helps starting hot or cold, and helps stop "cough stopping" with heavy rear brake use

When i start the atv with the choke it stays on , but when the atv is started without the choke it shuts off. My atv is a Yamaha grizzly


The choke should only be used when starting cold. After the bike is warmed up you can turn the choke off. If it keeps shutting off after being warmed up for a few minutes, then check your gas/air ratio for the idle air mixture knob. Loosen it up 1/4 turn to allow more gas to flow.

Engine cutting out with the choke off


Adjust your idle screw on your carb so that it gets more gas just sitting there at idle. Tighten the screw one and a quarter turn and then start the bike. Adjust the idle to where you think it sounds normal. If that doesnt work check your float in your float bowl, it might be stuck in the down position. Clean with some carb cleaner spray and make sure it moves freely before putting the float bowl back on, youll have to choke it or prime the carb again to get it started. All the choke does is let in more gas and oxegen so you might want to check how far the carbs close when you push the choke back in. Is it impeading any normal carb setting. Check that too. Good luck.
