Ah--the title is exactly right.....I had some free time yesterday afternoon, and had used my little C-120A to move some stuff around, but it kept 'bogging down"/ running rough at WOT--a couple time it just cut off..
Would start right back up--but only run @ idle for a few minutes....:fing20:
Well--these old Kohler's are built to run wide open--so I go get some tools..
It was already sitting under the big tree in my back yard, so I decided to 'wrench' a little right there, accompanied by a nice breeze...
Have to take the muffler off the front of the engine first, so I can check the points. Boy--the muffler was still pretty hot after sitting for awhile..(??)
File that away a for later..
1. Points were gapped open a little too much--I gave them a couple
rub-downs with some clean emory cloth, then reset to .020. I traced all the ign. wires back to source and they all looked good. Changed the in-line fuel filter.
Cleaned and re-gapped the plug.
2. Got on-Put the ear muffs on--hit the key--she fired right up--waited a few minutes, gradually ran it up to full throttle-for five minutes of so---
no back down/ cutting out -nothing!!!:fing32:
BTW--muffler is still lying on the ground....
The exhaust port at the outlet of the muffler is all black--like it was runnuing too rich--but the little stub pipe coming out of the eng. is kinda grayish/white looking--as was the spark plug...Again--(???)
Anyway--I ran it up and down my road, down to the pond and around the R/R tracks, and back-- pulling the little utility trailer with about 60lbs. or so in it for 20 minutes, and it never missed a beat again..
What do you folks think?
Muffler clogging up? Something inside it sweeling up when hot? This was the muffler on it when I bought it about 4 years ago--looks pretty good from the outside, but....
Need some answers--I remember years ago Chevy and Pontiac cars hAD problem with inner exhaust pipes swelling up, but a little tractor??
Couple of pictures--and last one is afore-mentioned 'shade tree":sidelaugh
