Default F2 won't start, worked fine yesterday...

Well, this is strange. My 92' F2 was working perfectly last night, and now it won't start at all. I filled up last night, and today I convinced myself I accidentally put diesel in it, but alas, that is not the case (The gas station doesn't even carry it, it turns out). So I have no clue what could be wrong with it. It was a little cold this morning so I started it with the choke and turned the choke off after about 30 seconds, and wasn't able to rev the engine without it dying. After that, I couldn't get it to start at all. I tried in the afternoon when it was warm out, and still nothing.

I have even tried to deflood the engine thinking that may be the problem (Turn the kill switch on, turn the fuel valve off, take it off choke, and use the starter) and that still did nothing. Any suggestions? Thanks.

Hmmm....fuel, air, spark....that's all you need. Seems you have air and you are confident the fuel is oky....check for spark. See if the plugs are firing, if the connections are fouled. If you are not getting any voltage to the plugs check the Regulator/Rectifier...though they usually burn out from getting too hot, not in cold weather. You may want to just drain off the fuel and get new fuel if there is any question about it.

Did you turn the fuel on or off since then? Sounds like what mine did when the fuel tank switch messed up.

Like i said on a later post, check the vaccuum hose that is connected to the petcock. If it isn't connected between the #1 carb and the petcock the fuel can be on and still not get any fuel because of the diaphram check valve in it. if your hose is connected check for leaks
