I put one aside for you. Best of luck. Ron Colonna

I had all the data on disk but no way to transfer the files to a thumb drive. The computer I used was dead. I only had an IPad. I wasn’t looking to buy a new computer. I finally bit the bullet and dug into the old computer electronics and solved the problem. It may not last long. I have 10 thumb...

I was recently able to get my old desktop computer running and am now able to transfer the Offenhauser plans on to a thumb drive. I am selling copies for $45 US. Payment can be made through PayPal to [email protected] check or money order to : Ron Colonna, 107 Lexington Drive, McKeesport...

Just a note on how I adjust my carbs. I remove the exhaust manifold and look directly into the combustion chambers while the engine is running. I adjust each needle for a nice blue flame at the exit of each combustion chamber. I watch for a consistent flame throughout the throttle range. Easy...

Terry: I have tried to explain the vernier idea to other builders of this engine in years past. Very few people have been able to grasp the concept on their own. Your explanation of it is excellent. Great job as usual!

Dave: Are you one of us guys that can’t get gasoline to burn? Sometimes it seems that way. I went through the same problems with my Novi engine. Your description of the smells of fuel burning and the unloading of the starter work load brought back the frustration of all that work and no results...

Hey Dave: Happened to be browsing around this site and came across your engine build. Hope it all turns out and runs well. Sure looks up to your high standards as far as machining goes. If anyone can figure it out; it would be you. I will be watching for the video of the first run. Just getting...

Terry: I love your advance set up. I designed a mechanical advance for my Sealion using fly weights working against a garter spring . It causes the magnet disc to rotate in the advance direction as the rpm increases much in the same way as the advance used to work on older model cars. It works...

Guys: I am still using the old Floyd Carter designed board with a Modelelectric coil and powered by two 2 volt lead acid cells wired in series for four volts. This ignition has proven to be both reliable and capable of firing four plugs to high rpms. The difference with my engine is that I also...

Terry: a spark gap in series with the plug can be a good thing. Spark intensifiers were and still are sold and some people swear by them. The additional gap is said to allow the voltage to build before the plug fires. At any rate it is said that the added gap only adds about a hundred ohms more...

Terry: That Voodoo notch became necessary when the original smaller starter clutch was unable to handle the compression load for any length of time. I kept going larger and the interference with the gear became a problem. Cutting the notch and adding the piece back in works quite well and has...

My Sealion uses a gear pump as a water pump. It pushes a lot of water through small passages and keeps the engine cool. Designed by Westbury in the 1950’s I think. Proven design.

The reason for short runs at the shows is two fold. First,If I allow the engine to run for any extended period, I get flak from people saying it is too loud and their conversations are being interrupted. Secondly the water pump and cooling system is totally insufficient for the heat this thing...

Looking good!

Terry: after about a year or so of running with the case hardened gears, I had a tooth break off one of the gears. That tooth went through most of the gear train and wiped out most of the rest of them. I machined another set from 1144 . Ten years later, the second set has held up very well. Like...

Harry Miller knew how to make an engine pretty as well as functional. A design that was hard to beat and has stood the test of time.

Sorry for the mix up. The two breathers on the one cover are tied together as you have done and vented to the oil tank. I call the cover on the intake side of the engine the front cover and the one on the exhaust side the rear cover. That isn’t correct terminology, but just how I mentally think...

I checked with my brother. The guy’s name was Don Francisco.
