Fuel Mixture Removable Plug

[mluder]

Need some advice -

I wondered why my engine was running a little spotty. While checking fluid levels,etc. I found that somewhere along the way I lost my removable plug for the fuel mixture adjustment hole.

I have tried to find a rubber stopper or cork that was small enough to do the job until I couldorder a replacement from Toby up at DMCNW but can't find anything small enough.

Anyone have any suggestions for a specific fix? The weather is supposed to be nice next week and I don't want to wait for the new removable plug to show up.

Thanks
Cheers

A wooden golf tee works nicely in a pinch!

I've used golf tees, rubber stoppers, M6 bolts wrapped in electrical tape and several other things. Even a piece of tape over the hole is better than nothing.

I got a whole mess of different size rubber stoppers from the odds and ends drawer at Lowes and just tried them til one fit. And it fits awesome, way tighter than the plug-on-a-stick that has been used for years and years. I don't have any idea what the size was but it's out there.

Duct tape.

Worked perfectly until I got my lil plug.

You could also whittle a pencil to a point and stick it into the hole. A piece of electrical tape is as good as anything too.

Thanks everybody.

I tried the parts bins at Home Depot but they had limited selection. Lowes is definitely better in that department so I'll try their. If not I've definitely got a few golf tees lying around and since they seem to do me little good on the golf course, this makes it worth having them.

Okay guys, I've been searching high and low for a month. I know every which way to seal that hole, but how do you actually open it up? I just drilled into what felt like very soft aluminum till I hit bottom. It feels like steel. I could see no gap between the cylindrical tube and any plug in the bottom. Is that whole cylinder/flange assembly a plug? I see pictures with it still attached with a plug sticking out the middle and am now completely confused.

Bob,

Best attach a picture so we can help!

Figured it out. I found this post:

That mentions the steel I was hitting. It's to stop you from dropping chips down inside the mixture control unit and gives you something to push against with the screw when you screw into the aluminum plug.

It doesn't say anything about getting the steel disc out if it separates from the plug or what to do if it falls down into the hole.

I used a small dental pick to move it, and sure enough it dropped right in. Removing that took a small magnetic pickup tool (magnet on the end of a telescoping rod). I'm good now.

edit: I'll add that info to a How-To and will later round it out with some pictures.
