Re: GT186 revs Question

Check the alignment of the pick up coil to the flywheel tangs. If they are out of alignment it won't rev higher than about 6000 rpm.

Re: GT186 revs Question

if it was mine I would do one thing at a time richen the needle jet 266 or 268 first then try advancing the ignition; I would set the ignition at 2000rpm around 23-24 degrees

Re: GT186 revs Question

264 needle jet?
is it weak that may stop it pulling under load; if you drop the throttle a little does it run slightly better

Re: Semi hydraulic set up
