Did you have the screw backed out when you installed the top????

If you did not have the fuel screw back out. You have broken the AFC lever. At the least you need a new fuel screw and AFC lever.

no it wont back out now what i did was wrapped a wire around that lever and held it forward got the top back on with the screw out then pulled the wire out when i got them tightened im starting to think the runaway is from the throttle levers ive been lookin at some posts

btitus · 11-02-2009, 10:11 PM

ok i tried every position on the lever i got runaway and no start i cant get it to idle unless i hold my foot on the pedal someone have any idea wat it could be

I would like to help, seriously. I know sometimes I can come across gruff with a "know it all" attitude but, before I can assit you in your quest, you are seriously going to need to use punctuation in what you write as I simply do not understand what you are attempting to convey. I'm sorry.

For an example; In your last post, you stated, I think, that you have tried every position of the throttle lever (in reference to the shaft) and you have run-a-way AND no start?????

I also don't understand the part about snapping off the full power screw and did not mention if you resolved this. I also don't know what your doing with the wire..........

I tried to be as kind as possible here. Punctuation is a must. That is why we have it.

I would like to know more about your situation to offer you some ideas.

hey no big deal. I put that spring in and tried to back out the full power screw and it snapped off i cant get it out. So i put a wire to hold the lever forward that the full power screw pushes on. i got the top on and put every thing together . Turned the key wouldnt start so i held the pedal down a little bit and it started up . But as soon as i let go of the pedal it shut off. I figured it was the marks on the shaft and plate. So i turned it a tick mark and i got runaway wot. I have no idea whats going wrong . thanks i hope this is more understandable . if you want you can call me 412 216 5090

there is no reason the full power screw should break.
UNLESS you had tightened it too tight in the first place and when you went to lossen it it broke.
OR (lefty loosey righty tighty) you were backwards and tightened the screw instead of loosening it.

no i was loosening it and it snapped off. I did tighten it as far as it would go beforehand though. But i would like to know what i should do i sorta need the truck and i cant get it running.

Greenleaf · 11-04-2009, 04:56 PM

If the screw is still in there, get it out and buy a new screw. You likely have buggared the threads in the aluminum top.

A wire isn't needed to get this assembly back on the pump. I know some have done that to skip a step or two, but I have read many a post such as your that result in problems and broken parts.

The best method is to read about this assembly, how it works and go slow. By reading ahead you'll know what to expect, how to do it and have minimal (if any) problems.

This task is quite simple IF you don't try to rush it and skip a step like NOT removing all the piece that get in the way. It is a must to make scetches of the parts and take notes about the adjustments beforehand.

What you now need to do is remove the top if not already. Then make sure you didn't break anything. Many break the governor arm.

k thanks. i dont think i will be able to get the screw out though. Is there somewere to get a new top or a screw. Im in PA

Greenleaf · 11-04-2009, 05:14 PM

Yes. This is what you want. The screw can be had new from any Bosch dealer. You don't want to know the cost of the top. You really need to get a used one from a parts guru. Many guys have old pumps. But you will most likely have to buy an entire junked pump for that top.

You really don't need the same top with the air fuel limiter if you can locate one from another application.

If it were I, I'd get a used one and rebuild it i.e. new throttle shaft and bushing with all new O rings and remove or modify that lever (reverse lever) inside the top. One thing to think about: if you are having troubles with a governor spring swap, you likley will not feel comfortable remanning a pump top. Get it done by a pump guru.

The reason the threads are messed up and the screw broken is because some will turn the screw so tight that the O ring boss will bottom-out inside the cast aluminum and sieze.
