Help!!

[andymini]

Something is wrong with my npede,it will start and run for about 1 or 2 seconds and then cut out.It keeps doing it!My glow plug is fine,and when it does run for more than 2 seconds it seems to gradually rev higher and higher then cuts out.
Can u help?

is it cold... or really just little cold, u gotta drive slow for a minute to wam up the engine then go.

sounds like a mixture problem, can't think if it's rich or lean, but try resetting both hsn and lsn.
hi: between 2.5 and 2.25 turns out
lo: 1.5 (i think) or just flush w/ throttle arm
idle: 1.5mm opening when throttle closed

also could be a leak, possibly in fuel lines, or engine seals, or a bad tank primer.

sounds like it's running to lean, you could have a leak in the fuel lines or tank. You could be getting air in the fuel system somehow but before you check anything else try richening the fuel mixture and see if that helps.

are you driving it right after it starts, if you are try letting it idle for a minute or so to warm the engine up. This may help.

[npede man]

ya it does sound lean. richen it up to default and tune from there.
