Thats what its all about.
Most of the time when I get someone at tech support they have just learned the english and ifn the answer aint in their script book your outta luck.
Gotta love them offshore call centers.
But hopefully the rebuild works out.

I just repowered my horse with the Kohler ch-270, 7 hp, 208cc, which is an awesome little motor. That being said, has anyone else used this and or a similar size motor. I have clay and I feel that this motor is not sufficient. The old briggs 7 I/C would just bear down and dig deeper, this motor stalls out and even was knocking when tilling. And no the oil sensor is not the problem. I'm looking for a Honda gx 240 or 270 but they come with a 1" inch shaft. I see different people have put these on a troybilt so I was wondering what they did to make it work? Cut and rekey the shaft, bore out the pulley, is there an aftermarket 1" pulley?

Sounds like to engine is running too lean.
What does the spark plug color look like?

Remove the plug and post us a photo.

you CAN buy pulleys(sheaves) with a 1" bore easily.. I don't see the problem..

But can you buy a troybilt 2 speed pulley in 1". It's a double pulley with 2 different diameters.

208 cc 7 HP Kohler is perfectly adequate for 20 inch horse, if it's running properly.
In my experience some of the new engines are fitted with too small carburetor main jet which makes the engine run at a very lean mixture and will bog down when full load is applied.

If that is the case, re-jetting the carburetor would be pretty low cost easy fix.


Remove the spark plug and post us a photo please.

My pre PTO Horse came with the electric start 8HP Briggs Stratton IC engine. Did a Repower for a friend on his Horse Tiller with the 9HP INTEK overhead valve engine. Lots of power but think it is no longer made look at the 1650 now.

Thx, I will check it out

I do agree with you that the motor should be sufficient. If I didn't have the larger 7hp b/s motor on there already I wouldn't have known there was such a difference. The current models come with a 208cc on the little broncos and a 306cc on the horse. that right there speaks volumes. What's the old saying? No substituion for displacement.

Makes me wonder what HP / Torque the Horse gearbox worm drive etc. are rated for?

I have had a 16 inch wide Pony Pro-Line with Honda GX160 5.5 HP engine since 1996 and it has never been lacking in engine power.

I wish it had more weight, bigger wheels and two speeds instead of just one speed, which is why I bought a 1976 20 inch wide Horse I, with 6 HP 221 cc Tecumseh HH60 engine little over month ago.

The HH60 seems to be perfectly adequate for this tiller and unlike the newer engines, both high, and low speed jets are easily adjustable on these older carburetors (on the other hand, the Honda GX160 in the Pony has newer needed any adjusting at all!).
