Hey Guys - I have attached a few pictures of my kart here. Specifically the governor arm. It seems like this engine is really held back from what it should be able to do. Doesn’t accelerate like it should and takes a while to get the speed up. It seems the engine may not be running at full capacity. Any ideas for the Kart? Maybe I am expecting too much out of this engine? Pictures attached.

Why would a new engine not be an option? If I got a new engine, what type would you recommend that would fit with the comet 30 torque converter?

I figured you might not have 150 bucks to drop on a predator 212. But a predator 212 should just bolt in with very little modifications.

Tecumseh did make some good engines. They have been used in A LOT of applications with a lot of success. Did this problem just start happening? There are several factors that could be causing this. Is the throttle actuating to full capacity? What is the gearing on this cart? Does it reach speed and does the engine reach full RPM eventually?

I would check to ensure the throttle is going actuating all the way when the pedal is pressed. That’s the easiest and quickest check (hence checking first). I would hate for you to look at spending money on another motor for a simple issue.

The old flatheads were good until they weren't, I've never heard of seen any of the OHV Tecumseh engines running good.

I cant say for that specific engine, just that Tecumseh in general did make some good engines that ran very well. Im not familiar with any particular models. We have one on a garden tiller that is ancient and still fires right up without a single issue. I didnt mean this engine was good, just not going to down Tecumseh as a whole.

Definitely don’t go bigger than a 212? How fast would the 212 go roughly?
With my 224 (the "MAX performance" version of the 212) I hit 40 in my kart with a 30 series CVT. It's all stock gearing and tire size, and I don't know either spec. But if you are looking for less speed they do come with a throttle stop screw installed

Tecumseh made good engines in the 70s and earlier, but not any time recently. That's why you haven't seen them on anything new in a long time.

I will check on the throttle. the kart in general does reach speed and full rpm eventually, but it takes forever to get there.

What is the top speed once you get up to speed? GPS app on your phone should give you a decent idea. Does it spit and sputter while trying to get to speed or does it sounds fairly healthy?

I have owned a couple of 2 seater yerf- dog karts with the Tecumseh engine. Both said 6.5 hp. I think yours might be 5.5 hp. One of mine would get up to almost
30 mph. The other was lucky to hit 25 mph. I put a 196cc clone engine on one and it gets to 35, and pretty quickly. A predator 212 will help a lot. For about $30 more, a predator 224 is even stronger. Same size, same weight, same bolt pattern. If you can afford the little extra, buy the 224. FWIW I gave the original Tecumseh engine to some kids in my neighborhood. Not bad engines, just not very powerful.

You could do a governor delete. It involves tearing the engine apart though.
I know that is the correct way, and the way l have done it,, but outta curosity, why?
the aparatus inside is secure, without any real chance causing trouble. For short term, is there a problem? Am l missing something?
