96 225TLRS yam

No top end. Stalls when given gas. Here's what I have done so far.
Idles at 800 rpm with muffs. Hit choke lever, no chg in rpm. Sprayed carb clearner into each cyl- no chg in rpm.
Pumped fuel blub- no chg.
Ck'd all plugs( looked wet). regapped/cleaned/ put back in. checked spark- all Ok.
Good new gas.\
Comp 120 all cyl.
Any ideas????
Thanks

One other point. When I put it in gear it stalls out. I can fiddle with the throttle and sometimes get her to half speed, but that's it. No upper rpms

Be sure the timing arm on the side of the engine is advancing and if it is, be sure the timer base under the flywheel is still connected and moving with the timing arm.
