MWQ Good Guess, It's A Capped Idle Mixture Screw
 

A few months back we were in a discussion about adjusting a 110 carb and the question of weather or not a plug down and to the left of the idle adjustment was a plug or a capped idle mixture screw. I was doing PM on my son's and pulled the card for cleaning. So while I had the carb off I pulled the the cap and it does cover an idle mixture screw. MWQ gotta hand it to you you do know your stuff.

Lucky guess.. :)

Thanks for letting me know. Did you check how many turns out it was set at stock?

Im gonna guess under 1 turn out.

Good to know! Thanks for posting this. My 2009 Taotao 110 has the same cap in place. No issues yet, but the kids haven't clocked much time on it at all yet. The little bugger lights right off anytime we want it to though.

My son has close to 100 hours on his and it was getting hard to start so I decided to do a good PM service on it. Here's what I found,

Carb pilot jet clogged
Green/Yellow coil wire hanging on by 2 strands
Rear gas tank mount broken
Intake valve under .002", Exhaust valve under .004"

BTW the ID plate on the front says Intake & Exhaust valve clearance should be set between .005" and .009".

MWQ I didn't think to check where it was set, with the above list I kinda had my hands full. I did give it a 1/4 turn in each direction to see if there was a spring under the screw and there is.

100 hrs? Cool!!

That seems pretty much like normal wear and tear...

Id never set valves that loose.. well my KTM is .0048 but its not exactly a air cooled Honda copy.

Thats ok...you were real busy..but if you get the chance Im real curious how lean its set.

Okay you got me curious. Why wouldn't you set valves that loose? I just picked up a John Deere mower with a Kawasaki 422cc engine and it calls for .006" valve clearance. It's a much bigger engine; is there a correlation between displacement and valve clearance? If so I can see why you say you wouldn't set them that loose. I set the valves on the Tao Tao to .007 just to pick a center point and she seems to idle much smoother. Should I set them to the .005 spec?

The main reason is Ive never seen a spec that loose.. My 4 stroke Hondas are/were set at .002...Set my Jetmoto 125 at that because Id set all my Hondas at .002...Now if I adjusted them id go for .004... but twice that kinda scares me..

I dont think that has anything to do with it..I set my XL600 Honda at .002... its got 4 valves and 1 cam... all I can think of is the Chinese guy who made the manual messed up on his metric to english conversion..

But if it works for you....


EDIT... Ive never seen a spec that loose on a motorcycle/atv engine..

Got a chance to go riding yesterday and tune it in.

3/4 turn

At .007 they're real noisy. Next chance I get I'm setting them to .004 as suggested.
