Turns over but won't start (I USED SEARCH)

I'd be surprised if you have particles in the gas so bad that they won't start on clean carbs. Is the gas in your fuel line coming through like mud?

To rule out the fuel issue, put some gas in a small container and fill the carb bowls. If it starts from that clean fuel, then your tank/petcock are indeed performing some kind of petrol to mud alchemy.

If you are now getting spark but not firing, check your timing. If spark and air fuel don't meet, they cannot fall in love.

She runs!!!

She runs!!!

First time I've heard her run in 2 months. I forgot what she sounded like. So I did a complete overhaul of the inside of the tank with evaporust (which I have pictures but the write up on here is very well done) and I cleaned out the carbs. I had to manually suck the vacuum tube to make sure gas was coming out and it was. So we fired her up and she sounds great. I am still having a problem keeping the idle after a minute or two. She ends up bogging down and shutting off, but I will work on that tomorrow. Can any one point me in the right direction? I assume I will have to do some fine tuning with the carbs? Is that what "jetting" is? Or playing with the air mixture screws? (Which I have set to 2 turns out).

Anyways, thanks for all the help. I will try and use search more often. Hopefully I can atleast get a "test ride" tomorrow if the rain stops.
