Question TECUMSEN Small Engine Problem

Hey Y'all,

I got this old ROPER 14 HP Yard tractor & I have got it to run but it lopes & then it will Throw the govener off & go full throttle & flood.

I have cleaned the tank fuel filter & plug .
Replaced the float.

I am not Familiar with a few things.

like the screw on the bowl.

& the breather looking thing on the top.

& the rectangle box on the carb??

I thought it might be a burnt valve but if you hold on to the govener it will level out untill it gets too much gas.

The 2 adjustment screw have no effect on the way it runs.

Any help is greatly appreiciated.


thanks

Screen on the bowl? Air filter? It's pretty dirty looking. The retangular thing on the side of the carb is a diaphram fuel pump. The screw on top is the throttle stop adjustment. There should be a screw on the bottow of the fuel bowl us the main jet and the screw in the side should be the idle adjustment. That's a pretty old looking engine...has it been sitting around for a long time? If so, the carb probably needs a kit put in it....

On the smaller versions that have a similar looking carb bowl, I used to go crazy trying to get them to run and then idle.

I finally went to a good old time mower shop. The guy showed me what goes wrong. The jet fitting in the center of the fuel bowl is a long brass threaded deal that has 2 different sized holes drilled in from the side. One is big enough to spot, but the other is so small that you need to know where it is to be able to spot it. It was right near the beginning of the external threads and use a strand from a wire brush to clean it out.

This is not the main adjuster screw, rather the brass thing that it screws into.

Not saying this is what's wrong, but it's easy to check.

Screw on the bowl its knurled just like the side air mixture screw.
I think I have a Pix

F&J so is that hidyhole on the carb or on the side or bottom screw ?

Do I need to pull off the carb?

It is a pretty old tractor but is heavier than my other & I use it to jockey my trailers around . I have a very small yard & It's damn near impossible to jockey with the dualie.

This one Purs pretty good { in between lopes}
& it has more than 2X the HP

I took the pipe bumper off my old Ford for a counter weight. Now I can move my flat bed no problem.

Plus I have some other attachments that make my life easier {when they work},Think of it as a mini Tractor .

Next I have plans to make a Bush hog for it.

But the "Roberts Rule': is if your gonna run junk better have two

Thanks!

No need to take the carb off. That hex nut that the lower knurled screw fits into; just a 7/16 wrench I think. It's the one that holds the bowl on. Pull that out and look closely on the sides of it. Like I said, on the smaller engines, they all had the same 2 holes in every carb I saw....5hp, 6 & 8. I know your is way bigger, but the carb design looks the same. But the smallest hole is real easy to miss!, especially if it's plugged with dirt or rust.


You don't need to tell me about small garden tractors being able to do amazing things!

This is the most common small engine problem if you dont shut the gas off and run the bowl dry every time. I have fixed many small engines with exactly this issue.
