'99 Workhorse throttle/gov/belt adjustment .....
Alright all you Workhorse owners ....... Meet Molly
I picked this '99 Jacobsen up about three weeks ago ...... I guess for a song and a dance which was tough because I do neither. OK, I gave $400. She was beaten regularly on a farm here in North Florida where they raise and compete horses and show-dogs. The fourth pic ...... is of her broken heart (a seized 350) .......... I ended up replacing with a donor engine taken in on a trade ......... so after scavenging/rebuilding the carb and timing chest and pulleys, I was able to get out of it with a couple of days worth of sweat equity .......... not too bad. Ok here what's up with it now. In it's prior life someone tinkered with the carb/Gov/pedal adjustment and had it all out of whack. Maybe thats why the engine took a dump in the first place ... Molly cranks and runs fine now after a couple of days of giving me fits trying to dial it in ......... I can at least get it to run and ease into the throttle without cutting on and off at low speed (idle) One thing that bothered me that I didn't think looked right is the "extra" bit of throttle cable at the front of this pulley The microswitch was adjusted all the way to the front(left) of the throw and after looking at some of the parts taken in on that trade I adjusted this one the same way and I think ironed that part out ... I'm here this time to see if anyone can see anything out of the ordinary with this gov. adjustment doo-doo. There is no pulling power to speak of .. meaning I can climb a decent hill as long as I don't stop........ if I do it's almost like it doesn't have enough oomph to get back going again and end up backing down the hill .........The engine doesn't seem to be able to rev near high enough to MAKE it climb efficiently ........ hell, at all for that matter. I read somewhere in here about shorter belts and might be interested in that eventually ..... but for right now getting the throttle/pulling issues straightened out would be fine ...... Any suggestions? Thanks |

Re: '99 Workhorse throttle/gov/belt adjustment .....
Boris and I have been discussing this for a couple days and figured we'd throw it out here for help. The belt appears to be the stock size. We were hoping it was a short belt making it a little jerky on the response. The cart won't go slow and doesn't seem to rev to the top speed. We can adjust the goverenor in the rest of the way for the high RPM, but I doubt that will help the slow speed. We're looking at the linkage and throttle travel. Anyone have any other ideas??

Re: '99 Workhorse throttle/gov/belt adjustment .....
The throttle cable looks to be adjusted too tight. I am referring to the picture just below the microswitch picture. Lets look some more.....

Re: '99 Workhorse throttle/gov/belt adjustment .....
Here's some for comparison. I don't have the microswitch pic, but this cart is stock...The govener is cranked in and that is all. The other stuff hasn't been touched.
I see what Mike is saying. The cable on ruredy's has some slack, this stock cart has slack at the same point. We were looking at ruredy's pictures earlier... Maybe these will help. This is an '01 Workhorse. |

Re: '99 Workhorse throttle/gov/belt adjustment .....
Here is what I have to do on occassion at the shop when we get a ?massaged? cart in for help.
Take ALL your linkages and control wires and loosen them Make sure that your carb is fully closing, back out the govenor adjustment. Go crazy and TRY to make it slow. You're going to have to find a starting point, then adjust back to where you want it. Tony - It's like setting the reel to bedknife on a greensmower. Sometimes you gotta get it all the way loose to get it square again? |

Re: '99 Workhorse throttle/gov/belt adjustment .....
Thanks Mike for looking at this with me ...... and thank you again Tony ...
Mike, thats what I did, took all of the linkages off got it to idle as it should and then worked my way back up to the carb. ......... Getting that slack out of the cable at the front is what is throwing me for a loop. I posed the question to Tony ..... Could this cable have been replaced and this one is just longer? 72085602 are the #'s written on the cable. I'm starting to think of things like .... Maybe the routing of the cable caused some "extra slack" to appear. ... |

Re: '99 Workhorse throttle/gov/belt adjustment .....
Those older cables did tend to stretch a bit. Don't fuss too much over than one, just make sure that you have about a 1/2" movement in it from side to side...
Does it look like the govenor linkage is moving correctly on the top of the tranny? |

Re: '99 Workhorse throttle/gov/belt adjustment .....
I understand the reel to bedknife thing oh too well. I'm already grinding 'em
Loosening up and starting over os probably the easiest way to go. See y'all tomorow |

I just looked at a replacement cable and saw that there are threaded adjusters on both ends of the cable........ I'm not positive because I'm not going to crawl around on the wet ground tonight but I don't think I saw an adjuster on the throttle-box end of the cable .... Will do Tony ...... I'll start at square one. Thanks for the help Guys ....... We'll mess with it again tomorrow |
