Default Thrown timing and expelling fuel?

Just ran into an issue with my 94 F2 I haven't run into before.
Had the alternator cover off to service the alternator coil.
I did a 'dry fit', replaced the cover without gasket and only a few bolts to see if it would crank and start, it did and ran fine.
Went ahead and popped it off and applied the gasket and during the process of trying to mate the cover and get the stator gear pin to align noticed the starter gear was slightly off line. Rotated the flywheel slightly (First mistake? Had this issue last time and a small rotation didn't result in any issues, lucky?) to get the pin to seat all the way and proceeded to mate the cover.
Took the bike outside to fire it up, fired up but seemed off timing, faltered and stalled while simultaneously spewing gas from somewhere between carbs 2 and 3.

Hoping there is no permant damage.
So off timing and flooded carbs? Suggestions?

I'm no expert, but I don't think so on the timing - the timing is run off the other side of the motor - cam chain should have rotated the valvetrain with the crankshaft. The other end of the crankshaft is where the pulse generator rotor is mounted, that's where the timing signal is sent to the ICM, and it is bolted to the crankshaft. So there's no physical way to move the timing independent of the rest of the motor by only rotating the flywheel on the alternator-side of the motor, cause everything in the motor moves in unison.

Unfortunately I'm puzzled why your carbs would go from working fine to spewing fuel - unless you've randomly suffered a fractured coupling between those carbs?

+1 on the timing advice. No way you could've moved it. Where exactly is the fuel spewing from? If it's running down the side, then I agree with first response, probably cracked that "T" between the carbs. If it's not coming from the side, you could've had a float stick on you. Slight tapping with handle of a screwdriver might get them to seat if that's the culprit.

Yeah if the spark plugs weren't removed (preventing building up of compression) you'd have to be friggen hulk hogan to advance these motors by hand!


You didn't do anything silly like tilt the bike over when working on it did you?

Thanks for the responses!

Hrm, glad it's not likely a timing issue.
Tilt, 90 degree at that, is the reason for the alternator work.
She was on her side in a gravel parking lot last week. No tilting between first test fire and second though. Likely flooded carbs then eh? Honestly, I know nothing about carbs!

On another note, the gas tank was leaking a fair bit from the vent tube overnight and today when I moved it, never had that happen. Possible that there is an issue with the tank that let too much fuel into the fuel system?
