Dear Forum,

Have a '99 200 Johnson.
Starts, idles and trolls like new.

Overall sounds great...however while smooth through 2500 rpms sometimes it sounds guttural above that...no power loss. Sometimes after returning to idle the next take off is without incidence through wide open.

Just replaced the bulb and under cowling filter with OEM...no improvement...haven't changed Racor seperator.

It doesn't act like a spark issue.

Always run Sta-bil 1oz/10gal. and usually Seafoam 1oz/gal.

Any thoughts would be greatly appreciated.

Have a nice weekend!

is this something that has developed with a motor that you have had for awhile?.....or something that you notice with a new to you motor?

Can I get your email.

I took a video last week.

Rebuilt carbs in May and it ran great until around July 10.


Same symptoms have returned.

Thanks
