I had planned on installing set of 1.3:1 ratio rocker arms to turn a .225 stock camshaft into a .292 lift torque monster in the previous episodes of "The Killer Tiller" 179cc engine prep videos. But I was unable to complete the install as they required a billet guide plate to fit the push rods found in the LCT once the 1.3:1 rockers were installed. I went ahead with the assembly but ordered the billet guide plate for 1.3:1 rockers. The billet push rod guide plate has arrived and so this is the install video.

A VERY cool engine review is now up! The Anbull 223cc engine: https://www.amazon.com/AnbullHorizon...
Is it like the Predator 224 or Wildcat 223 engines? A bit of both? Check out the video to find out!

1.3:1 ratio rockers are a good mod upgrade and cheap power for nonHemi Honda clone type engines. You have to keep in mind that not only is your valve lift multiplied but also the ramp profile of the stock camshaft is accelerated. This not only opens the valves higher for more valve lift, it also opens and closes the valve faster than the 1:1 stock ratio rockers ever could.
There are a few things to watch out for too. These are great additions for stock cams and stock springs. If you have racing valve springs with a lot of seat pressure, you'll be putting a lot of stress on the 1.3:1 rockers and a lot of pressure on your camshaft lobes. Stock camshafts tend to suffer under those conditions. Sometimes the 1.3:1 rockers can bend or break if put under too much spring pressure (anything over 22 LB springs is a definite no no.). It's a good idea to add a set of the split keeper type valve spring retainers if you'll be turning more than factory governed RPM. For stock governed applications, a stock camshaft and stock valve springs (1112LBS) should work fine. If you're looking for more performance and more RPM a set of 1822LB springs and split keepers/retainers would be the way to go IMO.
In this video we'll remove the valve cover and old rockers to get to the push rod guide plate location. We'll remove the old guide plate and install the new billet upgrade which will allow installation of the 1.3:1 ratio rockers! This is the 179cc LCT engine we prepared for installation on the "Killer Tiller". Since this will be a governed RPM engine that will turn no more than 4,000 RPM max, I'll keep the stock valve springs and retainers. I'm not interested in high rpm for this engine. I only want the .292 valve lift for added torque and horse pressure.

Where can you find the LCT 179cc $49.95 engine like this one?

A little background info on The "Killer Tiller" : It's an old "Huskee" brand garden tiller that was purchased at Tractor Supply Company (TSC) many years ago. It was old and tired when I bought it used back in the mid 1990's. I rebuilt the original 5 HP Briggs engine that came with the tiller as it was worn out when I got it. I used the tiller for many years and several times it was used to cultivate a 3 acre field of tobacco when the tractor broke down or was waiting for a part. So this thing has seen some major run time and hard use! Around 2004 I parked the tiller. It was again ready for an engine rebuild. Instead of rebuilding it, I purchased a new Craftsman brand garden tiller. The Craftsman tiller lasted a little less than 3 years before the Mickey Mouse gearbox gave out. That was pretty much the end of the "have a big garden" era for me. Since then I've used a small two stroke tiller and only had a very small garden. I decided to get the old tiller back into shape after finding the $49.95 new LCT 179cc engines. We'll see if there's still some work left in the old gal.
Thanks, Chris "Kentucky Fried Fixes"
