Re: 1982 Honda express won’t start

No

Re: 1982 Honda express won’t start

Okay

Re: 1982 Honda express won’t start

Jack Rutherford /

no points on the Urban Express. You need to pull the flywheel to get to the left side crank seal. Replace the bushing. I doubt it's causing much of issue though. What is the latest issue anyway?

Re: 1982 Honda express won’t start

So if it’s cold it will start but a little low on power. Then it will start reving up by itself and spin the tire. So if you hit the brake it will keep trying to rev up then die and can’t get started again so it can’t be driven.

The symptoms indicate a lean running condition. (Not enough fuel)

Jack has mentioned one possibility being the 40 year old rubber crank seals.

The other possibility is a carb running out of fuel. Plugged fuel line, in tank filter, carb jets.....

If your tank has rust or junk in it then vibration from the motor will knock it loose in no time and plug up a newly cleaned carb or jets.

Check the simple thing first.

Are you sure the carb is still clean and getting sufficient fuel flow?(edited)

Re: 1982 Honda express won’t start

I am not sure about it getting fuel flow or not but I’m pretty sure that there is no fuel filter on it and there is a little bit of gunk on the bottom of the gas tank.

I meant to say right side crank seal is under the flywheel.

Originally there should of been a plastic tube filter inside tank on top of petcock.

Right side is more common but either side could fail without warning.

Re: 1982 Honda express won’t start

I forgot about that filter

Re: 1982 Honda express won’t start

Did the seals look bad in the pictures. Also is there supposed to be oil inside the flywheel?

Re: 1982 Honda express won’t start

I took it outside and started it up and runs fine but weak at idle and after a couple of minutes it starts raving up by itself and just keeps reving up

Re: 1982 Honda express won’t start

All by itself even with the gas off.

If the back wheel's running really fast you have the throttle slide in backward. I'd have to read back through this all, but on a stock carb the angled opening should be facing you as you put it in. Not the full length opening you can see the spring through.

As to the seals: if you've opened it this far already just change them. the old ones will come out with picks. search through wiki and there's a way to get them off with one of those paint can openers you can pick up free at a hardware store. That's how I do it, but I think most people just stab them with a pick and pull them out. Please notice when you're buying that there are different sized seals on each side.

What if i'm holding the carb opposite from the way you hold it when inserting the slide ?

Re: 1982 Honda express won’t start

I don’t think that the slide is backwards because it idles fine at first then it starts reving up by itself.

Re: 1982 Honda express won’t start

Nevermind, was looking at the wrong page.(edited)

Have you ever owned a perfectly good runing moped???

Have you ever started said moped only to forget to turn on the fuel valve??

If you have ever experienced the afore mentioned it would be clear as day to you now.

Re: 1982 Honda express won’t start

Jack Rutherford /

can't see the right side seal until you remove the flywheel. You need a puller for that.

The urban has an auto choke - it may be revving up by itself because the choke is on. Can you let it rev for a minute or two and see if the choke shuts off?

You can also adjust the throttle stop screw on the carb. Turn it 1/2 turn to the left and see if that helps with the revving.

Slide put in wrong could also cause revving.

Re: 1982 Honda express won’t start

I know how to use the fuel valve and turned it off to so if it would stop running and it didn’t

Re: 1982 Honda express won’t start

Not going to read back through but if you haven't addressed the oil bath in the stator then you need to stop looking elsewhere until you have.

Lolz.

Crank seal.

Running lean.

Racing to the moon.

Is that a cracked motor mount I see???

Good eye. That can't be good.

Well, if the case is cracked then theres a one vacuum leak.

Re: 1982 Honda express won’t start

Where'd all the oil come from Owen?

Re: 1982 Honda express won’t start

Somebody must have put the oil in it. I cleaned it out though

Did it smell like gas?

Re: 1982 Honda express won’t start

Also, some more pics of that crack in your engine case are in order.

Re: 1982 Honda express won’t start

I don’t think it did

You already put it back together?
