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.

4hp NOS build-up (follow along series)

Oct
26

Here's from a box of parts I've recently been collecting to do the ever requested engine build-up. I will be doing this in steps as time permits. Currently you're looking at a 4hp period correct shortblock that was completely disassembled, thoroughly cleaned, and all metal on metal parts deglazed with 1000 grit sand paper and degreased, and regreased with WD-40. Unfortunately I started the carb-tank assembly before the website started.

Post your workhorses

Oct

Let's see your non-project workhorses. The mowers you use and abuse. The starts-every-time mow the lawn quick mower. Mine features a 21" classic style 3.5hp motor fixed handle. It started out as a roadside garage sale find. Was beat up but ran, used it for one season before I decided a rebuild. I rebuilt it and noticed the motor wasn't that great. Used it one more season and when it became hard to start I bought a NOS shortblock.

Rare 14" cemetery mower ready for duty. I'm hoping to upload Rocco's Green Machine images and then display them in a gallery.

Sensation Mowers website launched

Sep

OK Sensational group members. Your patience has paid off. We carved our own little spot out of the 'net. Thanks to a very active and able group member (not me) I was able to secure our domain name and already have a title page. Bookmark http://www.sensation-mowers.com and check in periodically on the progress. This will still be an active group and I'll work on getting all the (most) data over to our site.
