Left the choke on..

[BMPoland1993]

Hey,

I accidentally left the choke lever in the engaged position on my 420cc engine buggy, and I let my friend ride it.. for 30 minutes. He didn't notice, but I did as soon as I got on it. I turned off the engine, disengaged the choke lever, and tried firing up the engine. I have a straight pipe header on my engine, and when turning the ignition key, the pipe produces giant blue flames, with and "Whoomph" sound to them. Of course the enigne does not start up as usual.

I guess it's flooded, but I wanted to know for sure, so here I am.

I would appreciate any help.

Thank you,

B.

Pulled and inspected spark plug yet? Wondering if it looks wet, smells like gas, or no smell, color of it, etc.

I tried pulling the spark plug out yesterday in the darkness, but ended up unscrewing the main thread from the engine block. Will try again today.

 

[jmaack]

wait. what?

Yesterday I tried unlocking the front door of my house, but wound up driving to Chicago. Sorry, just having a little fun.

Oh man, I have so got to see what that is! Please include a picture of what a "main thread" is, and how it relates to a spark plug. The only thought coming into my head is of a helical insert fitted into a stripped-out hole.

Yeah, that was from the last time he tried to install the plug in the dark

Guys, I was equipped with a flashlight! What I meant was that there is a threaded insert, which is screwed into the block of the engine. Into that insert goes the spark plug. The last time I was inspecting the spark plug I must have tightened it a bit too much, thus locking it strongly within that "insert"... so when I tried to take the spark plug out last night, the insert came out, not the plug.

I hope that clears things up a little.

Wow, that sounds interesting, do you think you could post some pics.?

 

[panchothedog]

What kind of engine do you have ? Have never heard of a insert into which the spark plug is screwed onto. I think MAD got it right, sounds like a
heli -coil was put into a stripped out hole. By the way, and I'm not trying to be a smart *** here, if you don't have a lighted area to work on your kart wait until it gets daylight again. Flashlight repairs are for emergencies when you break down on the road and have no other choice.

You might want to change the oil and spark plug before restarting, or trying to. You also might want to use some red Loc-Tite on that heli-coil also. Just a little bit!

 

[madprofessor]

the insert came out, not the plug.

Do you mean the spark plug came out with a helicoil on it over the plug threads? If that's the case, I'd take a few minutes online to find a new helicoil the same size, and a new plug regardless of condition, and just start fresh.

 

[BMPoland1993]

@madprofessor Yes sir! That's exactly what happened.

so when I tried to take the spark plug out last night, the insert came out, not the plug.

It doesn't because what you're describing is not physically possible.

Can you at least take a picture of what's going on?

 

[NubsWithGuns]

So much doom and gloom right from the first reply over some unburnt fuel?

Also no one seemed to wonder how it ran for 30 minutes on the choke.
I would guess its time to stop using crap (ehtanol and dont bother me with your snake oil stabil crap lol),fuel and clean the carb.(this doesn't mean spray a can of carb cleaner down the throat, actually take it apart and clean it).

But maybe have someone else do it so we dont have another mystery insert coming out??

Changing the oil is a waste of time until it runs again.
Besides it not being the problem.

 

[MWKarter]

It would seem that if the heli-coil came out with the plug that either the heli-coil was improperly installed or he stripped out the heli-coil threads from the head. My .02

I think the OP might be describing one of these:

 

[MWKarter]

Probably. Thanks! Funny how things snowball pretty quick.

Non-fouler? New one on me. Quick look shows Rock Auto out of stock on all 14mm and 18mm, long reach and tapered, all of it. Here's something pretty cool that they do have, just FYI: More Information for PERFORMANCE TOOL W80539 (rockauto.com)..................
...........but here's what I think came out with his spark plug: More Information for LISLE 65200 (rockauto.com)
