Picked up another Victa with a Tecumseh Engine Tvs90
The mower had a heap of problems but I have nearly sorted them all.
I pulled the carby off and it was gunked up with dirt and more cr*p than I had seen before. The engine was flooding because fuel just ran out of the primer bulb when you filled up the tank.
I thoroughly cleaned the carby which and replaced the following components:
- Top and bottom o rings on the emulsifier
- Needle
- Seat
- Bowl seal
- Primer - old one was cracked
The previous tenant screwed around with the throttle cable but I have the adjusted properly now like all previous Tecumseh engines I have worked on.
The difference with this carby is that it has the mixture screw at the bottom and one additional small tube that comes out beside the emulisifer where the air intake comes in. (Not sure what that is). Would love advice on that.
I have the mower running really well at full speed. It doesn�t smoke and sings sweetly. It doesn�t miss a beat however I am not real happy with the idle.
Can anyone help me with getting the idle on this machine a little smoother. It was surging badly at the start but now the surge (hunting) is only so slight. I know is not right as other tecumseh�s have shown this issue.
Hoping for some advice on getting the right idle. I have tried adjusting the idle and full speed screws however I obviously haven�t got it quite right yet.
Thanks
Peter
