Honda help

[mr_velocity]

I know they don't scream and fly but there are a lot of brilliant people around here. I'm working on a 2001 Honda 130, I'm not getting any codes but the motor will not idle. At 3/4 throttle she'll barely run. I found that I'm not getting spark on 1 and 4, at least most of the time. Every once in a while the motor will rev up, so I'm assuming they're firing but then after about 2 - 3 seconds it goes right back down. I changed the coil from the other motor and still getting the same result.

Any ideas?

Don't fret. Inspect or replace the high pressure filter for the injection. Located on the stb.side behund the metal triangle that has phillip head screws holding it on,. also has a fuel line in the middle. If you have nippon denso plugs then replace with NGK. thanks Martin
