Quick and easy compression relief - on-off pull knob fix

[MobyDooDuckDong]

For those like me, frustrated with the compression relief on-off switch/knob because when pushed in to release the compression, the damn thing sits sooo far down into the cowling that it takes a pick, screwdriver or long nails to reach in and pull it back up.....this is a quick and easy fix. Cheap, and takes all but two minutes to do - most of all, it works. These are automotive plastic vacuum plugs. Scuff up the decompression knob with a razor knife to give the glue something to hold onto....then glue and stick 'er on. My GZ5000, the white cap worked - the 7910, Black cap but had to use two, damn thing sat soo low in the cowling. Thought id share since it was P me O to dig the damn thing out every time.

Not really sure why one would want to uncompress the saw before it fires but okay.

Not a "before it fires" issue - I just wanted to be able to pull the darn knob back out (when/if used) - w/o having to dig it out

They pop back out on their own when the engine fires up, no need to pull them up otherwise., only need to push them down.

When you're dealing with high compression saws, it's easier on the starter and the operator. Wish my Homelite 1050 had one. My Mac 125 would be nearly impossible to start without one.

Sorry about the way I replied I assumed you knew the way they are suppose to function.

Replace it.

My 660 swallowed an AM one last year that was installed by mistake. Only left a dent in the band and piston. Swallowed it at start-up then locked up.
