How much acetone do you think went into the gas?
Maybe some of the dissolved glue went through?

Have you recently ditched a girlfriend?
Don't tell Anyone about it.
If anyone says
Hey, I heard about your bike.
You know who did it.

Get it running , upright, not on sidestand, goose it and let it cut out.
Hit the kill switch, off the ignition,
Drain the bowl and see if it's full.

The dissolved glue may be in the screen by the float valve.
Or, possibly the screen on the petcock.
Does it run differently on prime?

Is the vacuum line full of holes?...

Also,.. how does the oil look in the sightglass.. (they tampered with your gascap,.. they may have tampered with your oil)...

Acetone won't harm the gas or affect the running.  But I hope you took the cap apart after you got it off and flushed it out.

check if you got glue in the gas cap vents.

That would be the most direct approach. If you drop the bowl, pull the float pin, drop the gas flow control and make sure that screen is clear. If the screws have never been out, don't expect it to be easy. They are not Phillips heads. They are JIS. But, a #2 Phillips that has been ground down, flattening the tip until the X fills the screw X it will work, but having the carb on the bench makes it much easier. A battery powered impact is really good. And some Good penetrating oil, half and half acetone and transmission fluid is great. Wintergreen oil, or Kroil, PB Blaster, in that order.  Antisieze going back together.

Act like something is kinda bugging you, but don't say what around the suspect. Not bad, just be slightly preoccupied, not upset, not angry, just distracted,,see if the suspect says anything about your bike.

If so, just ask,


Why, did you hear something?

Be careful of your tone, no  accusatory implications,

Watch the face...

ive done the petcock check and ive stripped and rebuilt the fuel cap, the petcock is working properly and the fuel tank is venting

it starts and runs perfectly untill i open the throttle, at that point it starts to miss fire, hold the throttle open to see if it clears itself and it just missfires worse. ive replaced the plug and checked the spark. ive also had the carb apart twice now, both times the float bol has been full of clean fuel, i even pulled the fuel line with it running and theres a good flow of fuel into the can.

am i right in the fact theres a decent spark means its fuel related and not electrical? i have had the tank and seat off n cant see anything cut or disconnected. i checked all the multi plugs were connected properly.

i dont know what to try next, any suggestions?? i need to get to work in less than 12hrs

its a HD sportster muffler ive got on it, theres what looks like a plate about 8 inch into the pipe. there doesnt seem to be any problem with the gasses getting out
