Ca77 stalling out

I can get the bike "running" but after a few seconds to a few minutes it will stall out on it's own and I give it has it bogs down and stalls out. Just started working on this bike 2 days ago so I'm as green as they come.

The first thought that comes to mind is a fuel problem. Is the fuel flowing freely from the tank? You can put a container under the carb and drain it to see if there is any garbage that comes out. Also, with the fuel valve on you should have a steady flow coming out of the drain on the carb (I'm assuming that there is a drain on the float bowl but its been a lot of years since I last worked on a 305). If you get garbage out or the flow is just a little trickle you will probably need to check and clean the fuel tank, fuel valve and carb (stuff in the float bowl can cause problems with fuel delivery so check the jets, etc). Also consider replacing the fuel line. Of course all of this depends on how long it's been setting, when the fuel system was last was last checked and serviced. I'm sure there are others with more knowledge that can analyze the problem better but this may be a start. Good luck.

Thank you I'll try cleaning out the bloat bowls and replacing the line and post the results!

I cleaned out the float bowl and there was some sediment in there. How would I go about cleaning the tank? It looks a little rusty inside.

Shut the petcock off and take the fuel line off the carb (it will probably be brittle and break or at least crack so have a new piece handy. I think it is 4.5 mm). Put the end into a pop bottle or other container and let it run to ensure that it keeps a continuous stream going.

If you have a continuous stream take your carb off and clean thoroughly and make sure the float is not rubbing on the sides of the bowl/body.

If you do not have a steady stream, you have a problem in your petcock. I can't remember if you need to drain the tank or if you can just turn the petcock off and unscrew the bowl on the petcock. You will need to take the screen out of the petcock and clean it and the bottom of the petcock body.

Good luck. I hope that helps.

PS you might want to rebuild the petcock while you are at it. Search this site for a description.

There's a bunch of ways to do this, but the low down and dirty way is to take a bunch of nuts and bolts, put them in the tank, and fill water+dish soap in there and slosh all of it around for awhile then pour it out. Gets the rust flakes and other junk out of there pretty good.

Otherwise, a better but more involved treatment is Electrolysis, you can Google that one.
