Please help. 250 bandit won't start

#1 Unread post by tonyhill »

I rode this bike around for 2 weeks before i bought it and didn't have a problem. About a month after i paid for it I started having trouble starting it. About a week after that it wouldn't start at all.

I just got it back from the shop where they fixed a broken carburetor spring, replaced a kinked fuel line and did a full service. But the bike still won't start. The mechanic doesn't know what else to try. The bike is getting fuel and spark and the compression is fine.

When I try to start it, it doesn't even get that "cough" sound, just the wind.

Any ideas before I give up on it?

Broken carburetor spring????? What function did the spring serve?

How do you know it's getting fuel?(what test are you using for this)

Are you using the choke? Is the choke working? (linkage, extra fuel to spark plug.....)

What kind of gunk comes out of the carburetor bowl when drained? What's the history of the gasoline in the tank both before you bought it and after?

Combustion is simple- air, fuel, compression, spark. At the right times and right combinations.

If the bike was running before - there's no good reason to give up yet. (This "mechanic" might be deficient in knowlege of the fundamentals or in persistance. Or doesn't have a service manual to help with how to check spark timing....)

I feel like this sounds like a fire issue more than fuel. I would but a inline spark tester on the spark plug wire and not rule it out till I saw the blue spark
