Did you check out the new bottom end? Could be something in the gearbox, basket, etc. Could also be counter balancer or bearing. I would pull covers and inspect.

Can you hear it if you manually turn the motor over? Pull the plug and turn the flywheel or press the kicker. See if you can hear it.

Yeah tried that cant hear nothing but noise def coming from that area I'm sure of that but flywheel sounds solid.

get an automotive stethoscope they really help pinpoint the noise location

I'll try some of them tips. Thanx. I can def hear it come from flywheel or pulse generator. It's funky if its warm its gone or if you rev up just alil it disappears. Confused

My thought was the Hinson basket hitting the primary gear on the crank. Sound is being transferred throu the crank to the fly wheel area...?

Take a long screwdriver and put it on different areas of the motor and put you ear to the handle to pinpoint the problem area. That works just like a stethoscope. You might also want to check for play in your counterbalancer bearing on that side. Just a few suggestions..

When I get home tonight ill check it out some more like the screw driver trick. Thanx. Checked counter balancer all bearing spun good ill check with stethoscope though. I'm also gonna try polanda's suggestion of rolling it over no plug and try to pinpoint noise. Hard to trace because it comes and goes. Anyone with a cr ignition got any suggestion it sounds like pulser when idled low on ignition.

Just got home and tried the stethoscope all the noise is generated at the pulse generator. Took flywheel off again nothing loose wiggling it around. It sounds like the pulse is arcing out something I'm gonna clean that n flywheel up with some Emory cloth n try again. No arc marks on anything but it sounds like that. I'll post back. Also turned motor over no plug in its quiet no obvious noise.
