That unmistakable exhaust note

[Stihl 041S]

Especially with twin straightpipe exhaust under a load.

Underline "under load".........almost to stall and then it finds itself and ROARS....... L model..........61 years ago.

I can still hear it.

The old 730 Diesel you could pull down low enough that it would actually run backwards.

It would sort of "burp" when it switched. Lol
Or really a Phart......

Yep and then instead of going forward you were all of a sudden going backwards and trying to get the old girl shut down because once it switched you no longer have oil pressure!

I have a model 70 diesel, .045 pistons, ported and polished head, 720 injectors fuel turn to the max. On the m&w dyno squeezed 65 horse, not to shabby considering it was a 40 horsepower tractor new. At night time you can see fire blowing out the straight pipe.

You want to see how bad your tractor is put a subsoiler behind it and drop it all the way down....
