Had to replace a spark plug due to it getting wet from 3 days of rain.
She started like a champ, ran fine all day.
Dropped to freezing again and brought her inside last night from the cold to put the plastics on... took her back out into the cold today, and she starts for about a minute with choke, then stalls out, and won't start back...
She backfires here and there now, and won't wake up.

Looks like water in the carbs?
(and i just put her back together too )
I'm gonna ballpark it to be the fast change in temp from outside to house?

Any suggestions? Kuro, Idodirt?

 

only thing i can think of is condensation of when you bring cold metal into room temp... water molecules build up. like when you take a cold beer outside on your back porch or patio or deck, and water starts building up on it... i could be totally wrong but throwing it out there!

 

No clue here. I'm expecting a very, very cranky F3 when the weather warms up.

 

further inspection shows flooding.. had some buildup coming outta the carbs, looks like one of the pistons isnt firing... or something like that... prolly some debris in the way now or water buildup... gonna take the tank off and do an inspection tomorrow when it warms up a lil.

 

Take the skirt off it. Works like a charm.

 

I'm not sure whether to laugh or be offended...

 

alrighty
further update shows a few interesting things.

fuel pump is good to go, even check the contacts and such.
no faulty sensors or relays
had to get a battery charger (20 bucks, good deal imo) at walmart
shows the battery is good.
airbox off and tank, looks like the carbs are the culprits, gonna give em a good clean tomorrow and take some pictures for you guys!
lines are all good, no leaks.

but the fuel lines are the originals, and getting to that rubber brittle stage.
sounds kinda dorky but ive got some old watercooling tubes from my computer that would fit perfect, and i wonder if they will do.







Any guys think this will be fine for the fuel lines?
there is no difference on the inside diameter as far as i can tell, just thicker.

Whatchathink?

 

Only thing I'd be worried about there is that those tubes aren't made to hold up long-term with gas flowing through them. You said they were made to push water/coolant, right?

I don't know anything really about the proper material for fuel lines and I'm not really sure how I'd go about researching it, just something I would consider.

 

If those hoses are silicone they wont hold up to gas, dont chance it. Tygon or rubber would be the best choice.

 

it is tygon tubing fyi
