Ok, here is one that ticks me off a bit.


Force 125 1989 1251X9B

Numbers on carb body TC 101A 809 66406 1


ok, so I tore apart the 1st carb today, here is my issue:

the kit came with 6 little brass caps

Anyway, On both of my carbs, only 5 of those caps are installed, and one of them has a hole punched in it. hard to see, but it is pictured below.

why is one missing? and one has a hole in it? should I leave the one missing? and leave the hole in?



also, the bigger problem, I got 3 of the caps off, the forth one was giving me problems, and then went all the way in instead :'( :'( :'(


it is the one right by the idle mixture screw directly below the brass bypass tube that runs throught the carb, I don't know how to get it out now, it is way in there. does that bypass tube run through to that cap? can I pull the bypass out and get to the plug that way?

One other thing, the bigger silver cap in the first pic was held in place with some sort of glue, what do you recommend?




Other than that, it's a breeze ;D

Re: Carb rebuild problem

Your kit is actually a generic kit meant for all carbs.
1. Do not remove the cap with the hole--It is a metered hole to control amount of air bleed.
2 Do not plug the hole that has no cap--it is probably a vent to maintain atmospheric pressure in the fuel bowl.
3. Try to shove a piece of welding rod up the idle tube to force out the plug if you remove the idle tube it may stay loose and give you problems to re-install it. Worst case, use a fine drill to drill it then insert a screw to pull it out. Do not **** up the idle tube.
4. The large silver plug is usually held in place by expanding it then sealing with the glue. Since it would be difficult for you to expand it try Black hardening Permatex. But for God's sake be careful. The last thing you want to do is to get some in the metered holes the plug covers. There goes your idle--there goes your pistons.

For the above reasons, I never rebuild carbs unless absolutely necessary. These carbs can be adequately cleaned using WD40, a piece of fine wire, and a pipe cleaner. Seems like WD dissolves varnish almost immediately. You only need to spray it through all orfices. A lot cheaper than a rebuild kit too!

Re: Carb rebuild problem

got it out, took a small drill bit, got it spinning, stopped the drill, while the bit was still spinning I jammed it into the cap (gently jammed it in :) ) it wedged into the cap and I was able to pull it right out.
