Why does my Virago motorcycle not run without a choke?
I’m trying to figure out what’s wrong with my Virago 250cc. It will only run if you have the choke on. If you let it off the choke the engine switches off. I originally thought that maybe the carbs were dirty. I ran some Seafoam through the fuel system, but it didn’t seem to help.
Why does my car not run with the choke on?
Dwight Coleman there are usually only a few possibilities if it only runs with the choke. One cause could be an air leak on the carb, head gasket, crankshaft seal. The other could be a clogged low speed and idle circuit.
Why does my Generator only run with the choke on?
A choke is active when it is closed;that is, it is on when it is closed. Normally you would keep it on (closed) until the engine warms up and then turn it off (open). If it really won’t run without the choke being closed/on then it’s not getting enough fuel and the carbs probably need cleaning.
What happens when you turn off the choke on an engine?
The choke increases the amount of fuel in the mixture, creating a richer mixture. This allows the engine to function at its best until it has warmed up enough to run on its normal operating fuel mixture. At that point the choke is turned off and the engine runs with a leaner fuel/air mixture.
Where is the choke on a pilot jet?
The pilot jet allows the gas to pass through and mix with the air while the engine is at idle (regardless of the choke being on or off). On many carburetors, it is located right below the throttle adjustment screw on the outside-top of the carburetor. There may be a plastic insert sitting on top of it.
What to do if your generator only runs on choke?
Luckily, this is an easy fix and you can probably take care of it without removing your carburetor. First, shut off the fuel valve. If your carburetor bowl has a drain screw, use a 10mm wrench to open it and allow any fuel in the bowl to drain out.
Why does my moped only run with choke on?
At half choke it would run smooth but did not have full power. After several carburetor dismantles I found the emulsion tube was stuck on a burr and needed to be screwed in about 4 more turns. That fixed the problem. On a two cycle moped engine I found a BB that sealed a drilled passage missing making the engine run lean and quit running.
