Please keep me updated with your progress I’d love to see another interpretation of it. I’m sure many improvements could be made but I had no idea if this would really work so it was built very quickly to prove the concept. As it turned out is has produced some good cams but I do think it...

Hi Thank you for your interest. It is the size of the off set disk in relation the the base circle disk that determine the nose radius. If it’s a bigger offset disk the the nose radius will be bigger and a smaller disk the radius will be smaller. I really only worked it out by trial and...

So, I have the engine disassembled again to finalise some plans that me and a friend have been drawing up. This has been very interesting to have a look at some of the internal parts of the engine. I have found some issues that I’m sure will really improve the running of the engine. Firstly was...

Thank you very much for your reply I really appreciate you sharing your experience with me. I did wonder if the advance would start very early as the cdi is seeing more triggers per revolution than the advance is designed for so it would advance earlier. Thank you again. Very helpful!

Hi I am now learning about using this cdi unit. I discovered this dc cdi unit after working on a fourstroke scooter at work and I thought this would be an interesting project to see if I my could work with a distributor on my inline four engine. One thing that came to mind was the auto advance...

Incredible attention to detail, the finish on your parts looks amazing. This has definitely given me a standard to aim for. Thank you for sharing!

Aha me too I think I tapped around 100 m3 threads for this engine!

Hey, the head and manifold studs are M3x0.5mm The liners are made as a light press fit and installed with some threebond 1215. I put a light smear under the top lip then pressed liner in until the bottom was in the water jacket area then turned the liner as I put another light smear of sealer...

Hi I wish i could cut threads that small nicely. These are purchased items.

Hi, your engine sounds like it’s going to be something very special. What sort of vehicle are you planning to put it in? I believe I might also know this other person in Suffolk. I have not yet met him but one of my good friends have promised to take me over to meet him. Some workshop visits...

This silicone is mould craft gp310 rtv. This is one of the softest silicones they make. I didn’t realise until I had purchased it that I could buy it in different hardnesses. This has been very good to prove the mould and practice with. I have ordered some of the two part putty like Gail uses...

Thank you for all of your comments guys. They really mean so much. After looking at so many of your engines in total awe of the quality of workmanship it has driven me to really try to step up the quality of mine. I still believe I have a long way to go but I am enjoying the learning. If anyone...

Well here are two videos. The first was one of the very first sustained runs. The second is after making having about 250ml of fuels through it with a heavier flywheel. Thanks for watching!

I would be interested too if you do find the plans for this engine. If the one in those pictures is your one then I believe that is the in fact the side valve version. I think that the definition flat head does generally mean that it’s side valve. Unless I have my definitions wrong. Here is a...

Hey guys, it runs!! Took about 15 mins of cranking over with regular pops to build up compression and I got a couple of short runs until eventually it kept running and just got better from there. The first run was very cobbled together, had a few oil leaks and a borrowed flywheel that wasn’t...
