Trick cam swap.

May
20

I had a tough time figuring out which motor to swap my newly reground cam into. I originally wanted to put it into a 4hp rebuild I had laying around but then boredom struck. Since my 3.5hp workhorse mower has been the recipient of every upgrade I came up with I decided to put the cam in there. Click title to read on... Once old cam was out I realized that the 4hp cam does not fit. I decided to quickly weld up material onto the lobes on the 3.5hp cam and grind..

Camshaft Tricks

I added 0.010" of lift to both lobes of this camshaft for a 4HP Briggs motor that's going into my next secret project. Should boost power significantly.

NOS Sensation Mower.

May
14

It would be unfair to call this a "restoration". This is as close to a brand new NOS original Sensation Lawnmower you're going to find. The Deck is fully original and refurbished, The wheels are brand new NOS Sensation wheels, The motor is built from brand new NOS original Briggs & Stratton parts in full Sensation specs. It's featured in the NOS 4HP build-up. Hear it run.

Paint

Apr

Fortunately Sensation has only a few colors that need to be matched in order to maintain or restore your machines. Most of the colors can be very closely matched with off the shelf rattle cans. I will post/list what I have come across through much trial and error over the years to keep my mowers new looking. Just click the title link. One main concern is obviously engine heat but it turns out it's not much of an issue as it seems.

Project corner *update*

UPDATE * (Putting the finishing touches on a restored deck that's going to run the NOS 4hp build-up motor. Also I'm working on a custom cam that I added 0.010" lift to both lobes that I'm going to put into another 4hp motor destined for the green side discharge mower. Stay tuned.) Here's a glimpse of what's going on in the shop now. Just refurbishing a deck to put my 4HP NOS block on and also scored a real neat side discharge mower. Was front wheel self propelled at one time.

Copper head gasket trial

Dec
07

Ever notice how thick the head gaskets are on Briggs and Stratton engines? I decided to fabricate a head gasket out of 0.020" thick copper using the old head gaskets as a template. In order to keep the edges of the copper gasket clean and smooth I kept it sandwiched between two pieces of thin wood and used a drill press to drill the bolt holes. I also annealed the copper before use. Measurements were taken before and after with a compression gauge with a fully warm motor.

Winter teardown

Dec
07

I decided to use the winter time to tear down and inspect my 3.5hp workhorse motor. This will be just a basic teardown, clean and inspect and reassemble. It runs great but has been hard to start lately. I built it 3 years ago and have run it hard for 3 years with just routine maintenance. The motor has served as the platform for any innovations I came up with to extract the most power out of it. As mentioned before it outperforms the 4hp and most 5hp motors.
