This doesn’t just apply to old cars. It could be anything mechanical.

This is particularly true if you work on OLD cars...

It’s been months since I’ve posted about what is going on at BRE because nothing has been going on. Actually I’ve turned down a good deal of work since my treatments started.As some know I’ve been unable to work due to complicated cancer treatments I am going through. Those treatments are going extremely well and my condition has greatly improved but I have a long way to go before I can get back to my work bench. I’m optimistic that I will be able to work in my shop again when the weather warms up, But, I am well enough now to pack up and ship kid kart bodies. I have a fair number of the most popular white and black bodies and one red and one blue on hand at this time.

Hat’s of to another kart racing related business in the Pittsburgh metropolitan area. The oval track chassis they build are impressive and fast and if you are oval track racing you can’t go wrong with them. Too bad they don’t make a kid kart chassis to complement our killer Comer 50 cc engines.

Is a chunk of carbon slowing you down?

This piece of carbon that had formed inside of a Comer C-51 muffler eventually broke off and created an intermittent power loss issue that is difficult to solve. When the engine isn't running the carbon falls to the bottom of the muffler. When it is running, especially at higher rpm, it gets blown up against the exit holes and becomes a very effective exhaust restrictor. Because this can happen over time, it is a good idea to occasionally remove the muffler and shake it. If there is rattling inside the muffler there most likely is a piece of carbon or multiple pieces inside. I have found the easiest way to get them out is to dip a screw driver into a tub of grease. Place the screw driver into the muffler entrance and gently shake the muffler so that the carbon pieces stick to the grease on the tip of the screw driver. Wipe the grease and carbon off and repeat as needed until it is all removed. In the cooler months I put mufflers in my wood stove to burn out the carbon. In doing that sometimes the chunks break off and don't totally burn up so I remove what is left as described above.

I need to let my customers who have been waiting for their engine work to be finished and have been waiting so long what the hold up is. Eventually I'll get them all finished but unfortunately I have a higher priority right now.
To make a long story short, I have recently been diagnosed with kidney cancer that has spread to my lungs and a couple other places. Other than fatigue, I don't feel bad which is surprising if you saw the MRI results. All of the tests and appointments needed to come up with the best treatment are my highest priority right now. I am confident that my doctors will come up with an effective treatment plan. If I have an engine of yours that you don't want to wait for just call and I'll be happy to send it back. I do plan to work in the shop between my other appointments. It helps to take my mind off of things.

Two years ago I abandoned a fuel system that I had spent several years developing because I found something simpler that would achieve the same things I was pursuing. Even still, my application was different than what the manufacturer had experience with, so one season of racing was dedicated to ironing out the details. I'm very glad I did. No, I don't have a dealership or any kind or a deal with Smart Carb, but I'm convinced that it is presently the best fuel system available for 2-stroke open kart engines. It's what I use and recommend for Vindicator engines.

Never liked the ignition wires hanging loose. This is the latest Vindicator improvement.

We do more that build killer Comer 50cc engines, custom bumpers, custom 3-D printed parts and Vindicator engines, we also publish American Muscle Kart, which we're pretty sure is the last remaining in-print, hard-copy, ,kart racing magazine in the USA.

I just got this email message from Roger.

"Wow Mark, fed ex showed up at my house today and I am a happy man. Your beautiful bumper fit perfectly, all the way down to the bushings. Could not be more happy and that includes the price. Thank you for getting right on that and getting it shipped. I hope to be back for another one soon."
