With the help of this forum, have proudly rebuild 2 MTD tractors now :-) -- first one unfortunately has different carby setup to second one so cant compare to help with following problem ..
Everything on second tractor now works, choke system works and engine starts and idles well, i THINK the governor is working, but unsure as I dont have easy access to an area of thick grass to test...
BUT one remaining niggle...i cannot increase the revs with the throttle lever..!
The tractor was pulled apart and sat in the corner for several months before I was able to re-assemble..
I am not sure if i have lost a small spring or connection from the throttle controls while it sat....
I have uploaded a video showing engine running, and how moving the throttle engages the choke correctly, but does not change revs, but if i stick a finger in and push back "carby lever" , i can make it rev fine Http://cybersol.com.au/uploads/throttle3.mp4
Am also attaching a picture of back of linkage plate with possible attachment points for a missing spring or wire?
AND have also attached the best pic I could find from the B&S info, with exploded diagram of the throttle plate, and that does not seem to show any missing linkages?!!!
Am i totally barking up the wrong tree? Totally confused at how to attack this,
