..scoot shuts down..

[wordslinger]

..so i was riding home today...not wide open, just kinda throttling back from time to time...

..scoot shuts down...

..won't fire, tries to fire and run, but it just won't ....

..a bud comes by, sees me, stops and we load it in th back of his truck..

..drop it out at home and it fires immediately when i hit the starter button..

..however...there seems to be a "hissing" sound from the carb that i don't ever recall hearing before...

..it'll run..but i don't hear the pop-pop-pop at idle throttle like before...more like pss-pss-pss...

..cracked reed?

..not that I know just how th' f8ck a reed works, 

..   ..

...upon further inspection, and let me give some background..

..i took out the 748-18-28 belt, due to the damages it sustained during my a50 ncy torque drive delima..

..installed, what i thought was the "new" 23100" belt i had, but was actually the belt that was on th' ppl when i bought it...

..mistake...

..because, i had went to 9 grm rollers with the long belt, and they apparently put too much pressure on that old belt...

..snapped three teeth from it, and that's when my scoot died...

..over-revved?? when the belt slipped on the torque driver??

..scoot runs, but with much less oomph...

..reckon i'm gonna get into some two-strokin' experience before i really wanted too...

That don't sound good.Whats the plug look like.Try another and cross your fingers.check the compression.

[wordslinger]

..plug is dry and a rich brown color...

..put new plug in, with no change..

..i rode it to work today, and it has definately lost some power..

..initial take-off is almost normal, but then engine drops rpms, and the power loss..

..i never attempted to wind it out...

[art]

Maybe some old filter in the main jet or compression loss comes to mind hope it's a jet.

[wordslinger]

..not old filter for sure..i'm runniing a k&n..all that's been eliminated and the carburetor thoroughly cleaned...

..everything was fine until the teeth snapped from the belt...

..then it just died, and would not fire enough to crank and run until it cooled down...

..to check the reeds, i only need to remove the intake manifold, correct??

..are the seals generally re-usuable, or should I wait until i order some to dis-assemble...

[art]

Ya the intake is easy.Iv'e been lucky on all my scoots as far a re-using gaskets,but theres allways that one!

[wordslinger]

..cool..

..can you think of any reason that a belt dropping teeth would damage the reeds??

..i didn't really hear the engine rev high..but i DO have the hissing noise that is coming from the carb....

[art]

Thats kinda wierd,Don't see how the two are related,but hay you wanted to look at those reeds any way  performance wize i'd say dirty main,hissing wize reeds or worse.

[wordslinger]

...the hissing actually becomes a "whistle" while riding...

..as cars go by, i can hear a distinctive high-pitched whistle rebounding back to me...

[wordslinger]

...and i can still hit over 50 mph, if i let it go...but i'm keeping it held back until i figure this out...

..it's just not the strong beastie it was before the old belt sh** th' bed...

[art]

Hmm.guessing at this point,but gets worse when under a load,maybe a toothe stuck in the clutch or bell or is it deffinetly the engine,check those reeds   copression after that,reed stuck in cylinder  

[wordslinger]

..imma get me a compression tester tomorrow...i need one for troubleshooting the a50 anyway...

..any specs on a tester that i need to be looking for??...thread size..connections, in general??

[art]

Bring a spark plug,pretty common size,you want 100+psi so i'm told I think 120 the magic#Did you read my post about the gates belt in your look out world! I think harbor freight has one withh the 3 sizes we lost them all! but there cheap.

[wordslinger]

..yeah, i thot of the spark plug right after i posted that...lol...

..i missed ur post on the othe rthread tho...

..imma try to find what i need local...i need it NOWWWW!!!!
