Return to idle problem..'88 80q

[MXHOWES at aol.com]

When you drive around and shift at 3000 the rpm's do not drop right away as
you take your foot off the gas, it kind of hangs at 3000 and slowly comes
down. If you take it up to 3000 and just hold it there for a few seconds then
shift the rpm's will drop as expected, quickley to below 2000 then slowly
back to a idle. This is NOT a problem with the throtle cable or the
'Deceleration damper'.
The 80q is in proper tune but it does feel like it has a 200# flywheel.

Thanks, Jim
