Attached pic. Tecumseh TVS90 engine, 3.5hp. Is the carb linkage connected correctly? Would appreciate comment or ,if not right, where to find resource to connect the right way.

Flipped it and terminated it in the hole that is 180 degrees from where it originally was. Got it started, but only idles very slowly. Can manually speed it up by moving linkage to full throttle, but goes back to idle upon release. Am trying to figure out how to 'static adjust' the govenor. Any help on this task would be appreciated. Many thanks....:smile:

After further searching, you're absolutely right! Thanks for the help from you and Shedmechanic. Also looking for help with adjusting the govenor. While idleing (no throttle control on mower), there is slack in the spring linkage that goes from the 'govenor arm' to a stationary attachment. Should there be NO slack? Do I need to 'static adjust' the govenor? I would be grateful for any help with this. Thanks again...
Great forum!

The link to the governor arm on the bottom....was that arm in that hole originally? It has been a long time since I worked on a Tecumseh. But there is supposed to be some slack, but when the engine speeds up, the spring should start tightening up so that the governor can slow down the engine. If you didn't mess with the governor before, I wouldn't mess with it unless you know how to adjust the governor, otherwise you will grenade your engine if you are not correct.

Actually, when the throttle is manually opened fully (fast) while the engine is off, the governor linkage pulls the governor arm to the left which compresses the spring (loosens/gives it some slack). When the throttle is closed (idle), the governor linkage moves to the right and tightens/stretches the spring. Also, the full travel of the governor arm is only about an inch of travel at the tip of the arm. Does this seem to be a correct amount of travel?

Shedmechanic, thanks for all the good info you are providing.

As long as the spring is the correct spring for the engine and the linkage is in the correct place, there should be no problem. When the throttle is opened all the way, there is supposed to be slack in the spring so that when the engine starts to rev up past a certain point, the spring will tighten up against the governor and slow the engine back down so that it doesn't run too fast and self destruct.

Hello: if all the wires are rigth, you must bend the speed control braquet, to the head increase the speed, very little move variates a lot of speed.
