QT50 Won’t run/start with choke installed

So I got a proper throttle cable today as well as choke... I installed the cable, ran great. Next I figured bikes warm let’s just drop the brass stopper in the choke barrel. Put it all back together. Nothing. Played with my mixture screws, nothing.

I’ve been running with the choke just capped off, literally it’s had a cap screw where the cable fitting is on the carb top.

This is an OEM VM12 Mikuni carb on a pretty stock QT50.

Took the carb off, shook it upside down and got the choke plug out, put it back together, plugged the choke actuator hole in the top of the carb. Fired first kick.

Guess I’m running this way?

Slightly bigger main jet help maybe? I didn’t think that’d do anything for start or idle but who knows.

I’m running a cone air filter, oem(70) main jet

I would completely install the choke plug and the little spring to the cable and cable to the carb and choke lever. Adjust it correctly, then, with the engine cold, activate the choke and start the bike. Immediately turn the key to RUN. My engine is warm enough in less than 15 seconds. Move the choke lever to the run position. Feather the throttle to try to keep the engine running.

There is a spring? This is news to me. I’ve got 4 VM12’s and one Minky clone vm12.... and I’ve never seen some spring but this sure does explain a bit.... maybe.

So I just learned tonight by bikes flooding if I run it then turn it off and let it set for a bit(yes the chokes wide open for all points and purposes I guess, but it always is.

I have no run or start yet. I have an orange wire that I plug a male fitting into a genial fitting when I want to turn it on, if I’m lucky the coil has discharged before I go to plug it in.

I bet I can come up with something like that

Re: QT50 Won’t run/start with choke installed

I still don’t understand why it won’t run with the choke just in there.
