Thanks The parts are ordered and I hope to have it running again in a few days . I am also making another set of spark plugs, the Chinese plugs i am using sit to far into the head so are difficult to insulate properly. Brian.

Hi All I have blown one of the TIM 6 circuit boards on my 5 cylinder radial. Can any one tell me the part number of the hall effect transistor I need , I cant find a number on the item its self. Thanks Brian. H

Hi Carl Thank you for your question . I was adjusting the mixture screw to make the mix richer , Note that the engine ran on its initial prime from the pump at the rear of the carb but then stopped , I gradually increased the mix until the motor ran evenly then ran it for 15 minuets. THen...

At last the video give it a whirl . Brian.

After a lot of fiddling with the mixture and going over valve and ignition timing. IT RUNS the mixture requires further attention and the oil system jet has to be smaller. but it has no vibration after all my fears about that. Run time is 30 mins in two sessions. Video to follow...

Its been a long time again but the engine is almost ready to go all it needs is a oil tank non return valve (due in 2 days time) and a can of fuel.

Oops can someone remove the extra posts Finger trouble again . Thanks Brian H

Simms motor units produced corrected magneto's for radial engines , unfortunately it was all finished when I joined the diesel development lab a long long time ago. Brian.

I have made up a rig to test the pin positions on the master rod all the pistons come up at the correct 72° intervals so that's a relief. Brian.

Hi Michael. Yes the design is original I think. I need something to keep the brain cells active, I will be 80 this year and need my workshop more than ever. you can find me on you tube search for Brian Hogger I am at the moment doing video number 14 on this build. but don't hold your breath...

Found a diagram in my file . Brian.

Hi Marcus. To get the angles, I used my CAD program to draw the position of the master rod at each interval, then measured the angle for the new pin position. however it would be nice to confirm my findings. Thank you for your kind offer. Brian.

Thanks for the welcome back an all the good wishes. I think I have the oil pump firmly on the screen now so it's time to push on. Another view . Brian
