new carb and thoughts

Postby mozer71 » Fri Jun 01, 2018 1:54 pm

I received a new carb and it is so tiny. It is so small for a 4-cylinder, 4- stroke engine. I got to thinking about using the 154 and it used less fuel than a 16- 18 hp. air cooled engine going flat out.
I have pondered on this; all this heavy engine and flywheel and radiator and pto to a 59" deck. They really had something with the Farmall and their descendants . I don't believe this updraft carb with 1" throttle bore. No fuel pump/ gravity fed. Dang !

This engine (cub or numbered series) is surprisingly fuel efficient for its age.
Of course, being only approximately 18hp at the flywheel does seem like a small amount of horsepower for a 1 liter engine.

It is always great to have instant reply. Thank you! It is rather astounding how frugal these engines are. Been there, done heavy mowing for hours. Check the oil and water and Specifically blow out the radiator. With a wand at the end of the blow gun, you can really get behind and blow the bugs and grass out, forward. All those little " fireflies" / lightening bugs which everyone likes, can clog the radiator fins. It is a sturdy engine but excessive heat kills it. Rotten ass 15% ethanol and even 10% = No good for these. You know all this stuff.
Dang. 1971 and who knows what it went through before I got it. The deck was flat wore out.

I just the other day made a comment to a neighbor that my 14hp kohler on my cub cadet uses about double the gas on the same lawn as my 154.

Wagonmaster. Thanks for confirming what I've experienced. Keeping them in good tune and proper filling. I mean pure gas and bad or hasty filling. The gasoline runs over the tank and hits the belts and main drive pulley. Even worse, is that gasoline is around ignition components. No way!
Save 2 minutes and lose an hour wiping and blowing out the spilt gas.

Kinetic Energy of the flywheel mass and engine components is the reservoir of power.

Also the air cooled engines are usually turning more RPMs than a Cub. Some almost twice as much.
