110 help needed!

[Trouble]

Hi, as you have seen here (http://www.3wheelerworldforums.com/showthread.php?t=71079) i am working on a 1979 110, well i have have been working on it for the last 2 days and i got spark and i have got it to run! :w00t: but now, when you start it it will idle ok for about 5 secs then it starts to rev vary high, what could be making it do that?:confused:

Blocked air filter? Carb might be old and tired too, rebuild it.

i cleaned it all up inside and out befor i tryed to start it, and it seemed like every thing was in good working order.

[Trouble]

any buddy else?

[atctim]

sounds like it is getting starved for gas - too much air in the air gas ratio is leaning her out - thus the revving - does it stall out right after it idles high or not? Is the gas flowing freely into the carb? Pull off the gas line at the carb and see

it poors out of the line from the gas tank and it poors out of the carb.

[atctim]

sounds like your float is sticking - after it revs real high does the engine just shut off?

Do you have an air compressor and a can of carb cleaner?

i turn it off when it starts reving really high.



Do you have an air compressor and a can of carb cleaner?

yup and yup.

sounds like the float valve is sticking open.

Remove your carb.


remove all items pointed at in picture.

Spray a generous amount of carb cleaner into the small holes in the jets and all openings in carb - don;t miss anything.

Use your air compressor then to blow out all holes. Use you air compressor to blow into every nook, cranny, and port in the carb. Don't miss anything.

Reinstall carb and let us know how you made out.

[Trouble]

ok, will do!. oh and is that a 110 carb? cuz mine dosent look like that.

[atctim]

do the same on the jets you remove too! hold them up to the light - you should be able to see thru them before reinstalling

[Trouble]

ok, well i took it all part again and cleaned the hell out of it, the jets are clean and clear, the float moves good and every thing else is clean. but i put it back on filled it with gas, pulled the rope and it still did the same thing. started and then idled for about 5 secs then started to rev higher and higher. i am only running 1/2 the exhaust could that be making it do that? (it broke off)

thats the only exhaust i have on it.

oh and i dont have the air fillter hooked up yet.

[atctim]

have you played with the idle adjustment screw yet? It is a screw with a spring on it - you'll need to turn it in or out with a screw driver. Also - what condition is your throttle cable in? I had a bad cable that hung up once and it made it rev to the moon. Check that out too.

[Trouble]

no i havent, i will play with that next. the cable is in really good shape.

[Trouble]

ok, well i got it to idle right. i took it for a test drive to day and i have a new problem :(. it bogs way down, i cant give it more then 1/4 throttle or it will bog down so much it kills the engine. oh and it is back fireing when it bogs down and i let off the gas.

[atc4everbob]

Sounds like you still have carb issues. I know you don't want to hear that, but... Another thing I have not yet seen mentioned here on the board; while the bike is running take a can of starting fluid and spray in short bursts around the carb intake ends. If you have an air leak, the engine will rev. Do this on a cold engine to be safer. Are you sure your throttle is returning to idle? Do you hear a click when you snap the throttle on and off (while not running)? You're getting close - and whatever is wrong now is something fairly simple - yet aggravating. Good luck and keep us updated!

[Trouble]

ok, well, i have gone through and cleaned EVERY part and or hole i could find... again just to make sure i didnt miss some gunk. and it was clean. what i am seeing tho is it is sucking in a ton of air, is that normal? if you put your hand close to the opening it will suck your hand on to it, that is how much air it is sucking in. so when you give it gas, there is just way to much air. so when you give it gas it just cant give it enuff gas to match the air going in. how can i fix that? i have tryed messing with the screw but it dont make any difrints.

[firefirefire90]

First off, when you took the jets out, did you put them back in spec from what the manual asks? You might have put one in wrong. Are you running an airbox with filter? That could be your problem. If your not running a filter or anything you are just sucking in raw air and it might be to much for your carb to take.

[Trouble]

i dont have a manual, so i just put them back in the same way as i took them out. yes i have been runing it with the airbox on it, the fillter is gone tho.

[firefirefire90]

I would try to get a filter stat....this might be one reason your running bad. All the crud that is coming in there. Have you cleaned your airbox as well?

[Trouble]

yup, its nice and clean.

[atc4everbob]

Running without a filter could definitely be a problem. Before you do anything else, put a good filter on it. May well be it. Let us know.

[kwbyfrmhell]

one thing you might want to check if your bogging down is intake manifolds for leaks and the filter being to restrictive or clogged I had a problem with that on one of my 110s (homemade filter)

[Trouble]

ok well here is a video so you know what i am talking about better.

View My Video (http://video.tinypic.com/player.php?v=4z9h474)


P.S i know the video is bad, the screen on my camcorder broke so i couldnt see what i was filming, and i mostly made the video for the sound.

[84honda200s]

my vote is a mix of points and carb issues.






thats some good camera work for not having the mini screen.

[atc4everbob]

Yes, it may be a points issue. Easy to check. Gap should be .012-.016. If gap is ok, check the contacts for corrosion and burn.

[Trouble]

well i checked the gap today and its at .014, and the contacts are clean.

[atctim]

you may be getting too much air being open like it is. Do you have the airbox? I don't see it hooked up in the video - just an open carb. Hook up the airbox and use an old sock for now and put it over the element.

[Trouble]

yes i have a airbox, it runs the same way with it on.

[84honda200s]

well if it isnt a points, throttle cable issue that leaves the carb. at this point im stumped. as tim said put the air box on and use a sock as a air filter for now.

[Trouble]

could one of you tell me what the needle should be set at?
