Hey I'am working on a 1997 recon 250 it has great spark changed coil with one that works pulled carb apart it was spotless i think it may have weak compression because it won't even hit with starting fliud I checked the vavles their in toleance. does anyone know what compression should be? I'm a auto tech but haven't really ever played with atvs. the unit was runnig my son was driving down the road and it deid. he said it could start it but it would die within a few mins-help please.

Honda usually has a decompressor built into their cams, fair assesment that it should have around a hundred pounds or better, cranking with the throttle open. Leakdown is always handy, tells you that vavles and rings are sealing at TDC. It should still run up to about %15 2-5 % obout normal. Sounds like maybe water in the fuel or a venting problem? Start with the fuel tank and work your way to the carb. lots of miles on this unit? could have a plugged exhaust?
