Built completely from bar stock. It is designed to appear to be made from castings though, its a Jerry Howell design.

Thank You! And no I haven't tried placing a load on it with my hand or otherwise. I did not even make the optional drive pulley as I wasn't planning on using the engine for anything other than building a running engine. If it's like my others it will get put on display in our living room never...

And a link to the video:

All, Here is my Farm Boy engine completed. Thanks for all the help getting it running. Special thanks to Engine maker (Jim) for all his help and for the decals!

Got it all tore down for paint and and polishing. I think it was running a bit rich. This is after running for about an hour! It wouldn't run any leaner. Maybe I still have a fuel suction problem??

Thank you! That's a very generous offer!

Ran it for about 45 minutes straight tonight and I had water in it, prolly burned an ounce or so of fuel. It was way hotter than 98 but not crazy hot. I definitely need to tune it a bit to reduce number of hits and increase the misses. It sure does cost awhile between hits now and I'm sure it'll...

On another note, I've seen where alot of these engines just need the mixture screw barely opened. Mine seems to run best opened 5/8 of a turn. Here is a pic of the mixture needle.

I have been playing with the governor spring and have got it slowed down a bit. It still needs a bit more tweaking bit I am happy with it! Now I'm gonna tear it down and paint, polish and bling it up a bit. Yup I scoured this site for ideas for the sled and fuel tank and yes I used your ideas...

Here is the video: Any advice on getting it smoother and slower running? I also notice that when I touch engine while it's running I can feel a slight shock! Better ground needed I assume?

Ok I got it running and it ran fast! Had to install governor to slow it down:-) Found a couple problems that I got fixed up and it made the difference between sputtering and running:-) First was something Jim said about installing a new o-ring. Compression felt good but o-ring had been in...

That's a beauty! Looks and sounds great!

Yes, the instructions for wiring that ignition module and coil are full of confusion! The gentleman that sells these seems very nice and is always there to answer questions, the problem is I dont get the feeling he knows much about them. I email and asked about wiring this stuff up and he...

That was my impression as well. Yes, it seems to have very good compression and will give a nice bounce. Yes I discovered this last night. I wired up a new Hall Effect switch and was adjusting the timing and had the plug removed and also was checking the spark. The spark just wasnt very good...

Cogsy, Yes the needle valve is very sensitive, very easy to flood the engine out. I am thinking that is part of my problem, to much fuel at times shorts out the plug? I think? Intake Valve spring is another thing I have messed with quite a bit. When you spin the flywheel with your finger...

I would hate to have to ditch this system as it did cost a fair bit. Seems that many people have used them with success but at this point I am not one of them :) And I would have to find some room and a cam or something to actuate the points. As you might tell I am a bit ignorant about these...

Tony, My bad, I mis-typed. I have (4) AA batteries powering the ignition module, using a volt meter I get about 6.2 volts. The spark seems to be acceptable. Having the buzz chip in the module actually give me hundreds of sparks per second. When I purchased the ignition module everything I read...

That looks nice and cozy! Looks like a first rate job as well! I love the loft, great use of space.

All, I have completed the build of Farm Boy #495. I spent all of last winter building it and had everything done except the ignition system and getting it to run. I have recently spent several evenings setting up the ignition and trying to get it to run and have had almost zero luck. I got it to...

Hi all! Been a lurker for quite awhile but just signed up. I'm a tooling engineer with 30 years in the tool and die trade. I have been building engines for about 7 years now and have build mostly Jerry Howell designs. So far I've built (2) Super Sterling Fans, (2) Miser Engines, Vacuum...
