FWIW,

Jason was sanding jugs assymetrically on purpose on certain saws. Front to back, for exactly the reason Deets brought up + transfer height. His theory was intriguing and wasn't necessarily that hairbrained. If it had been done on a mill precisely, it may have worked out just fine.

Like most things, it's was the execution of his ideas that was the problem (and the end result).

I think he's just a dope head not caring if he fed up people's stuff.

Explain please.

I see what you are sayin Dan, now muh head hurts

I'm thinking that youre going to lose stroke if you cant the cylinder ..........
maybe not a huge amount, but if you imagine the bore, piston, and case as straight lines, as you move away from perpendicular, you lose stroke and increase squish as well as chamber size

Just thought maybe it was me missing something... [emoji12]

I would rather run a stock saw with just timing advance, muffler mod and base gasket delete with a straight 90* jug verses running a saw that had an angled, Kentucky Windage type angled job jug. Just me.

Angling the cylinder front to back isn't going to change port timing on one side vs the other. It can increase skirt wear.

Depending on how extreme, it would also send the bottom of the exhaust skirt into the crank lobes

It's science.

Y'all just don't understand.

There are some engines where the bore center does not intersect the crank axis. Usually the cylinder will be lead towards the power stroke side so the rod angle is less when the gasses are expanding. Unfortunately it creates a larger dwell time at top dead center.

Unless I'm still half asleep... I don't believe that would work. Piston rides in the bore so the base being cut on a forward lean would not effect timing at all. It would simply lower the jug timing wise, half of the distance of the difference between front and back.

Exactly.

Probably cause more unwanted vibration and premature wear as well.

That sure puts the term "maxed out" in perspective.

 

[jake wells]

there is a solution to this problem on the forum. if you would have contacted anyone else for there saw service here you wouldn't have any problem.

Jake, hind sight is 20/20. A little too late for that now.

well im sorry that is how my brain is interpreting this problem.

Fixed that for you.

 

[tree monkey]

well ok
wander what he charged for that

Sounded stock. My echo would blow that away. Lol

I have a husky 555 clearing saw that would probably actually benefit from a port jobber

I don't think the gear heads would hold up
