Every problem is different... I had a V belt slipping and after much head scratching found that the sheave was not deep enough forcing the friction to be on the bottom surface rather that the wedging action of the V flanks. A quick deepening of the sheave fixed it.

How true. Something has to grab your fancy before committing to a lot of work.

Peter, you can see the ignition box clamped on the right. I do not have the picture but is mounted on a "ready to run" display base including the Fuel and Oil Tanks Throttle and needle extension and the ignition trigger and HV. Had to extend the throttle and needle because one can not get near...

Plugs are Rimfire Ignition is a Moped CDI that I boxed with some circuit to adapt and select Leading Edge or Trailing Edge Trigger so I can use it on Hall Effect or Contact point. I move around the box from engine to engine. Lubrication is by all 3 method. It has an Oil Pump injecting through...

Thanks, Looks like a winner.

Next project may be the Sopwith Camel kit to hang in the living room. Lots of detail. Wife and I have not had a fight in a long time so this will be a good trigger.

Replaced the prop with a flywheel to test run. To prime I have to place a finger on the carburetor. There is no way to do it without meeting the turning propeller. Plus I am not fond of having an 18" propeller running while I move around.

458 Carburetor intake Won't let me attach any more pictures. Will Try later.

Just finished to build the Anzani Y without castings. That was above my skill level which has raised considerably during this construction. Mostly is a matter of imaginative fixturing and proper work sequence. Now I am ready for a something new. Like a TWO strokes Glow (or a sparker) around...

The Sulfur barrel seems to be used a trash can. Sulfur is something to be avoided at all costs is any Iron/Steel composition. Is lway listed as LESS then X%

I do not mean to damper your enthusiasm, but this forum does not lend itself to didactic. Sure, we discuss all sort of subject and share the common knowledge but what you need is like a course of study. I suggest you take advantage of the internet starting with Wikipedia. Then if you have a...

Ciao e benvenuto. If this is your first engine, building a radial engine is an ambition project. Here is my Edward 5 on the test bench.

Looks like $443.76 solution to a $39.99 problem Large drills tend to wander at start. There are inexpensive solutions: Shorter Machine drill or double drilling.

Some time back I built the Lanz tractor which has a quite large flame licker. Never been able to get it running. I read here how critical the flame position and surrounding is. In my immense wisdom I decided to omit the 3 perforated baffles/screens surrounding the flame thinking it was...

The repeated tightening may turn the mild steel interference fit into loose fit. No big deal, when that happens.

What stops me is when I encounter difficulties or made an error. Then I think and overthink the next operation but lack the motivation to get "back in the saddle" so to speak.

Dang, I wish I did see this before ordering a 22 x 10 Probably near stalling on the bench but I am not flying the engine so even a paint stirrer will do. I like the prop with the armored leading edge. I am planning of going with a wet crankcase No tank, just the pump.
