Cr 125 hardto start

[DConwheels]

I have a '93 Cr125 that is hard to start. I can usually bump start it and once it is going for a while I can start it again with no problems. If I try to cold start it I usually get nothing. My routine is: pull choke, kick moderately 2-4 times, push down choke and kick and kick and kick and kick and kick. If I don't turn throttle it sounds real muffled and no activity. If I turn the throttle it sounds as if it is trying to start but never really does. I recently took off top end, replaced gaskets, clean everything put new rings in, kept same piston, repacked silencer, cleaned carb 3 times, new plug, and new gas. Any ideas why it would not work with no throttle but closer with throttle open? Thanks for the help.

How many PSI of compression does it have?

its hopefully nothing bad, but you need to do a compression check, it can tell you alot about your engine, before its to late.

When you bump start it are you using your choke, and if so how does it idle? Have you tried starting fluid while kicking to see if that jumps it?

i've had a similar problem with my bike. my float height was so out of whack that it wouldn' start. i fixed that and now it runs great again

everybody who owns 2 stroke should know that you need compression and a clean carb to have that magical 1 or 2 kick start.

When you twist your throttle you're using different circuits in your carburetor, so it could be your starting circuit (choke).
