running problems--- Help!

[Renagade Dad]

1996 trx 90 Won't start with the choke, will start after 6-8 pulls with the throttle held wide open but then will not idle and die. I've had the carb off and cleaned it and the jets. When the engine warms up I've adjusted the idle and then it runs good but when it cools down I'm back to square 1. Any help would be appreciated.

i would start with a compression check and spark plug

Does any one know what the compression psi should be on this motor? I don't have a maintenance manual.

It is a Cylmer manual......., never checked our comp before. It does seem high seeing that my Banshee had 200+psi last time I checked it. :D
