Going to need the "Big Boy" ear plugs for that MOFO!MO-FLOWing the 603 still.
Gotta add a baffle so Simon’s ears don’t bleed
Try a coil. I never run mine much over 9k maybe. Always set them fat. Never had a problem. Bought used 101's. One needed a carb cleaning once. I hear horror stories, meh...For soldering steel we used 45% silver for a good seal/joint that would withstand heat, pressure vibration.
It is not cheap.
15% sylphos will work most times too.
With all solder get the parts clean and good flux.
I have 2 of those 4 mix motors on the bench.
They do not rev over 7500. Should be 10500.
Compression was 70psi on both, should be 90
Piston, bores, rings look fair so replaced rings.
Valves and seats look good and will hold mineral spirits in cylinder for hours with no leaking.
Cylinder pressure feels better but they only rev 8000.
Used 3 carbs, 1 rebuilt, 1 stock used and 1 new china carb.
All run the same, rich on the high.
Doing these as a favor but they are fighting me and cluttering up my bench.
About time to show them my hammer collection.
Good question for @MastermindUsed it on my high bread. Runs almost identical to an HD11.
Just to be clear to all, I’m using Tig Braze SilBronze, not a torch.For soldering steel we used 45% silver for a good seal/joint that would withstand heat, pressure vibration.

I know he drills every 461 carb he does. The last one I used was, for certain, a 58.
Perhaps they have changed at the factory?
This is an HD50 carb I got from CCC. I had to drill the jet.

Whether or not the 461 carbs you encounter have #70 jets in them or not.What was the question?
Nice good work. Thanks for the reply I've made my own muffler mods but I always had my friend braze them up for me but now I'll try it out myself with the silver solder.View attachment 136629 View attachment 136630 View attachment 136631 View attachment 136632
Yes sir. It’s all I use.
Even built an entire pipe out of copper, all brazed joints.
Never had a failure.

HD50 jet size
Lol. Big difference between the two looks like someone else has been in there before.Fixing a little over jetted problem.
