Default Briggs 5hp Fun Power linkage??

136212-1026-E1 5hp l-head go kart since carb rebuild will not accept throttle from the pedal but will rev fine moving the lever on the carb itself.
I seem to have an issue with a spring at the governor linkage (near the bottom tank bracket) This spring has one end in the shape of a triangle and fell off during tank removal.....I've been on partstree looking at all springs listed; none seem to match? Again, engine idles fine and revs fine but only using linkage right on carb.

possible build date: 9706-131E (tag is damaged) but "97" part clear..

This is what I have...spring connects remote throttle to govenor somehow....I have tried every which way and engine cuts out as soon as throttle applied at gas pedal....???

I actually tried that first....engine ran fine but carb to tank gasket was leaking. Replaced gasket and engine runs fine but will not accelerate from the gas pedal. Works fine if you use throttle plate arm to rev....what am I doing wrong here?? Engine actually cuts right out like shutting off ignition.

Hmm was the gas pedal working before or s this a new engine on the kart? Check that when you press the gas pedal the governor linkage on the tank moves back and fourth.

Engine ran ok, replaced leaking carb to tank gasket. Upon reassembly engine will die when gas pedal applied, but works fine if you manually rev engine at carb linkage (before and after spring problem fixed above.) Engine cuts out like losing ignition as soon as gas pedal depressed..

Sounds like its flooding when you press the pedal. With the engine reassembled press the pedal and watch the top of the carb. Does it open slowly or immediately move to WOT? if it moves immediately to WOT your flooding the kart.

Runs fine, not flooding - and works fine if you push on throttle linkage at carb. When you press on pedal, engine shuts right down...wiring issue??? I believe I hooked up wire at lower tank bracket same as before....

If the gear ratio is high or carb not tuned right it will flood the engine (both my 5hp Briggs did this on karts with a 5:1 Ratio) causing the engine to flood from the load. Disconnect your kill wire and see what happens

i have basically the same 5hp funpower and i had a similar issue when i hooked it back up to the linkage.i think when i hooked mine back up the way that looked right it was backwards. now im a bit of a noob but i "built", and i use the term loosely, a new on out of a metal coat hangar.

In figure #58 which is my setup; I do not have a wire going to the terminal in the upper right of bracket...(the one going from stud on LH upper of bracket)could this be my problem with engine quitting when throttle applied??

I think your ground wire is interfering when you give it gas, remove the wire and see what happens

In my picture, the yellow wire is coming from a kill switch located under the steering wheel. Look closely and you will see that there is a black wire under the same terminal, that black wire goes to the coil.

By the way your spring is bent, it should not look like a triangle, it should have a nice radius at the bottom, like a paperclip. Solomon nailed it when he edited your photo, just hope you make sense out of it.



I know this picture does not help you with your governor spring, but it might straighten you out on the coil wire. I'll see if i have a picture that more applies to your delima.

Your spring should look sorta like this. (Ignore the numbers, they do not apply to you)

In your picture you have a shorter wire coming from the coil, I believe that one attaches up near the carb.

Thanks to all above for great replies...my wiring looks just like above. Short wire above carb goes to on/off lever and choke lever assembly. I find it very strange (my luck) that engine ran fine except for carb leak and now I may have electrical problem....I will put back together and try again. I don't think my spring is bent or wrong but it wouldn't suprise me!!!

the cabr works fine via the butterfly valve on top, when using the pedal it faults, thier is an error in the Linkage. Does the governor arm move freely?
