Need a new ISP... this is becoming a habit.... th_wtf1 :fan:

Steve, do you have any plans for this distributor? I am starting to design a v4 and this would be exactly what I am looking for... Thanks! Doug

I like shiny... Thanks for the comments! Here's a little video of the Otto finished and running: http://www.youtube.com/watch?v=rmgmb5OuaW8 That is all.... Doug

Well.... I am officially done with the Otto, now it will be a discussion piece on my mantle. The number one question I get it is: "What do you do with it?". To which I respond: "Show it to you..." She runs really good; idles at about 900 steady and revs to 3500 with the softer springs...

well... I think I am now done with the Otto and will start spending some time designing the V4. Here is a pic of all the pieces that make up the engine... I did not realize how many bolts were in this thing... that's a lot of 6-32 tapping! The uprights are cut out and lightened. You can see the...

Well, I was able to spend a little time on the Otto this afternoon and nailed down the vapor tank. It works excellent and looks good to boot! I roughed out the sides and then turned the top portion on the lathe. It serves no real purpose to be round, I just thought it would look better. The...

Well... I had her up to 5600 RPM today running really smooth... Idles about 800... I tried to use a carb off an RC car with about the same results as the webster... bad... I whipped up a quick adapter for the 10mm carb The carb installed... it ran, but either idled or sputtered to 2000 RPM...

The build started on February 8th and there was a week without building because the plastic gears in the head popped some teeth (now have metal ones). The build log started on February 16th on Madmodder.net and was copied over here. I am really amazed at the sound that comes from this engine...

Well, I spent a few minutes tweaking the motor today. No new parts, just a timing wheel made from a 360 deg protractor. Here are some videos: The Engine running about 2500 RPM. Being as there is no real throttle to control RPM, you control it through mixture. Richer runs cooler and slower...

Got Gas... Got Spark... Got To Go!!!!!!!!!!!!!!!!!!!!!!!!!!!! THE OTTO LIVES!!!! I had another coil from junk weed eater and I got tired of waiting for the lighters to get here, so I epoxied some neo magnets to the flywheel and used one of the original coil mounting brackets from the Webster...

Well, I am officially out of things to do until the lighters arrive. I will probably work on the vapor tank tomorrow, but I plan to use the one off the webster in the beginning. I plan to put a belt powered fan on the engine after she starts running. Might not do much, but will look cool. The...

I cut the slot today and mounted the 192 tooth belt, though I think a 191 would have been PREFECT, it was not offered. I had to bore the holes larger in the cogs to 8mm drill, still do not have an 8mm drill. I drove all over today looking for one. I used a 5/16th and then made a reamer with my...

cogs and belt arrived today... yea... the belt calculator online was dead on! I bought one smaller and one bigger just in case. Tomorrow I strip the engine and cut some slots... Here is a link to the calculator: http://www.sdp-si.com/Cd/default.htm Vapor tank will be a glass tube with...

I'm running out of things to do without belts and ignition parts. Belt and cogs will be here tomorrow... I hope I got the right size... I redesigned the muffler. It looked like it might be a bit fragile and exposed and easily damaged or knocked off. Not that I am going to be tossing the motor...

Well... its been a few days since I have uploaded some pics, so, here you go... Let me first start off with a video of how you should listen to that little voice in your head when it says.. "be ready to grab it if something happens" http://www.youtube.com/watch?v=GFqtQNU0VmQ All is well...

Good day today. Cams, tappets, flywheel, and part of the ignition done. I blacked up the cam blanks and marked them as per the plans. Then I used the 36x4 belt sander to sand off the extra stock down to the 20mm lip. This is the finished intake cam. I will need to fine tune the timing...

Well, finished the crank bearing blocks, crank, and cam blanks. I cut the cams from 1 inch 4140. The OD is 24mm with a 17mm hub. I will cut the cam down to 20mm by removing the extra stock with the 4 inch belt sander down to the 20mm ledge I left on the hub side. Both cams are 11.5mm which...

Well, everything is mounted solid now and only a few things left to do. I might be making fumes this weekend... I made a center line on all the uprights and one down the center line on the base plate, lined them up and transferred the holes in the uprights to the base plate. After the 3 back...

I got all three uprights made, bearings in and some 40mm plate spacers roughed out. Now it REALLY looks like and engine... More to come tonight... took Sunday off to go play... Doug
