Cub verses 184

Looking at a 184 low boy, how do they compare to an old cub as far as power goes, looks like they have about the same cubic inch displacement. Did they turn up the rpm's? It has a 5 ft belly mower on it, the cub I used to have struggled with a 4 ft mower. Thanks for any input.

14 HP on the 184 compared to 9 on the older Cubs. RPM was turned up as well as different pistons. rods, head, carb.

The engines are the same C-60. I asked this same question on cub.com .

I was told that there isn't any differance other then the pistons ! The pistons have a off set piston pin location from that of a older cub.

The newer motor has higher compression and the rpms are turned up.

Based on the info that was given to me i bought a head off E-bay and cut it. I set it up in a Bridgeport and ended up cutting .060 off the deck , .040 to get it flat and .020 extra.

The results are great, i turned up the rpm 200rpms "wow".

Last summer a friend has a yellow 185 low boy that the motor needed to be rebuilt in , the head and rods are the same as the standard cub .

On hand held GPS the mph in 3rd was 9.8 mph [stock]. Now with the cut head and 200 rpm more it runs in third at 13 mph.

I plow alot of snow with it and really notice the differance and have used it a hole year so far and zero problems.

If you get a chance pull the exhaust manifold off it and look at the mismatch in ports.

My dads was as much as .312 [5/16] off, we port matched to the exhaust gasket. Can't say weather it made a big differance but it couldn't hurt. Seems to run smoother !

Hope this helps.
