    I finaly got a bike for my gebe and as I was setting up the engine on the mount it slipped and hit the ground.

    Landed on the aircleaner cover. Looked ok at first but I checked closer and it looks like the air cleaner plate cracked and broke into some pieces.

    Looks like it's just the plastic that has damage. I'm wondering if just super gluing the bits back together will work just fine or would it be better to try and replace it?

    I'm not mechanically inclined in any way so I'm a little unsure of what I should do here.

    Any advice would be appreciated!

    Superglue is at best a very temporary fix, if a fix at all.

    If you have all of the pieces, put it together carefully, and before doing anything else, make ab pattern from it. I'm pretty sure that the part can be odered for a few bucks.

    You should be able to get the part fairly easily from either the supplier of the kit or some other source - alot of gardening supplies places will carry that type of engine and will be able to order it in if they dont have it in stock.

    small engine repair shops can order them lawn mower repair shops also. If you live in a larger metro area it will not be to hard to find, look here:

    Heh, yeah, after (almost) gluing it all back together I can tell now I'll get a new part. I also found a couple places fairly close to get one. Thanks folks!

    Youd be surprised how much you can save with a two part glue or epoxy. 1 part glues are useless.

    That's for sure - once tested - super glue and others - out --- two part epoxys - next best thing to welding - in... There's the 5 min set up time epoxy for fast jobs - (sets up in 5 min - not cured). The overnight dry time epoxy may be the strongest ? Been using epoxy for over 40 years now - pretty darn amazing stuff !!! Two favorite brands are - JB Weld and Loc-Tight.. Happy Riding from - Mountainman

    Yeah chevy used two part to put truck bed panels on for some years. Stronger than a weld imo.

    Well, I called the regional distributer to find a service & parts shop & ended up just ordering a new part from them and got it today, the shops listed on the website, (within 20 miles) aren't R/S service centers anymore I guess.

    Is there any trick to getting those hoses off, (or on) from the old part? The manual says use a small screwdriver but I guess I'm a little afraid of tearing it and having to order again!

    I'm probably just being tentative since I haven't worked with these before...

    Oh, but I still picked up some J.B Weld for any future needs!

    Well, I'm back unfortunately with with a new problem. Put gas & oil in and took my gebe out for it's first test ride today start. Tried different choke positions, 1/2 and full open, made sure switch was "on" and still no luck, took her back inside.

    I pulled the spark plug and saw it was not "wet" with any gasoline. I also noticed it seems the primer pump isn't sucking up fuel into the carb, (I think that's what it's supposed to do right?) if it's the clear yellow hose.

    I take the gas cap off and looking inside, when I press the primer I do see bubbles coming out of the hose in the gas but don't see any go up the hose...if I'm supposed to see it go up, ( not sure). Do I just keep pressing that primer until I see something happening?

    Any ideas what I should try next or anything else that could be wrong? I'm a little unsure where to go from here.

    -Still waiting to ride :cry:

    hi sabala

    when it comes to the little primer button
    in short time -- you will develop a feel -- of when it's just right

    kind of reminds me of the birds and the bees here -- side tracked - sorry

    when pushing the primer at first - it pumps very easy - not much or no gas inside
    then we feel it tighten up - get's harder - there's gas in their now
    not to over due it at this point -- we are loaded -- with gas
    one or two more pumps at the most at this point - should do it

    wow - early in the morning - kind of fun trying to explain that
    got the old motor bike guy worked up
    pardon me -- while I go and see if my wife is awake yet..

    might be a good time to -- Ride That Thing - Mountainman

    Mmm-hmm Mountainman, ok, sooooo I keep pumping and pumping away but the juices do not seem to be flowing...

    I did get the gas into the hose, (hooked it to an eyedropper) and connected it back to carburetor but when pressing the primer, it will push the gas back down the hose and when I release the primer it does not suck it up.

    I took the hose off carburetor, (with gas still in it up to 1/4" from the outer end) had the primer pushed in then connected the hose back to carburetor and then released the primer pump hoping to suck it up the rest of the way but I could see the gas in the hose not going anywhere.

    Slowly pressing the primer pump only pushes the gas back down the tube into the tank.

    That is what it is supposed to do

    The clear hose is to return gas to the tank when you prime the carb
    The black? ( other ) hose sucks the gas into the carb

    Did you try starting it with half choke?
    no choke?

    hi - I had a lot of coffee this morning I see up above !!! I'll keep an eye on that.

    anyway - trouble with the primer pump
    not sure of your primer pump age
    guessing fairly new

    not sucking up the gas apparently ---

    when older as with any rubber type parts - primer bubble may crack
    causing it to lose suction - visual check - ok ?

    where the bubble connects - usually 4 screws - if loose of seal - possible problem also
    question -- are those 4 screws tight -- not to tight now - don't wish to strip

    might not hurt to take that little baby off of there - some inspecting and cleaning

    I hope that you understand -- just guessing here

    Forbisher, thanks for the info, I didn't know exactly what hoses did what. I went through the manual and online R/S manuals but couldn't find that particular info. So, I should NOT have any gas in that yellow tube then?

    Yes, I originally tried with choke 1/2 open, then fully open, then closed, no luck.

    Mountainman, I guess you had a good start to your morning-I hope! Engine is brand new and unused, has never been run. Yesterday was the first time I put oil and gas in and tried to start. I'll try to fire up again and if nothing happens, inspect and maybe take stuff apart!

    You also mentioned in another "no start" thread to put a little gas into where the spark plug is? Like take out the spark plug, put in a little gasoline where it, (sparkplug) goes then putting the plug back in? How much gas, a milliliter or more? Just trying to get all my options here...

    Thanks all, I'll keep trying.

    ...I also don't see any gas going into the bubble...if I'm supposed to...

    hi - ok -- it's never been run

    sometimes just a little hard at first
    after a little while of running -- first or second pull -- should start

    at this point -- don't take anything apart -- it's new

    when pushing that bulb -- give it a couple of firm pushes
    not tinky winky -- we are pushing gas through the system

    some strong pulls on the starter -- what's your book say about choke
    up above it seemed like you did fine - with the choke
    remembering -- to much choke may equal flooding

    yes - pulling the plug
    with a little time under our belts -- this can tell us much as you know
    running too rich - lean --- that plug at times tells us a story

    a little gas down that spark hole - shouldn't hurt anything
    very little -- less than a teaspoon
    be careful if this is your first time removing spark plug - not to strip threads
    when putting it back in..

    this may be better for now -- got a close friend who knows a little in regarding engins
    might have them fire it up for the first time
    because after the first time -- it's fun for a long time - sounds like this morning wooo

    the main reason we add a little gas down the spark plug hole is --

    if we get a slight firing of the engine -- we know it's a fuel problem - lack of

    if that plug looks wet -- we probably have plenty of fuel

    hope that you are up and running soon so you can -------

    yes - you should see it

    and feel it as you pump it in

    remember --- firmly pump -- until you feel the gas on your finger tip
    should happen within 5 pumps

    So, I was rechecking the online service manual...and realized...maybe it's good to check to see if the hoses are hooked up to where they are supposed to be. I saw the engine illustration where it talks about putting the engine back together and shows the breather and return pipe.

    Apparently after hooking up my new air cleaner plate I had misplaced a couple hoses...

    At least I know more about my engine now than I did yesterday!

    Heading back outside...don't think I'll be back for awhile...I hope!
