I can't find my old notebook with all the other saws I've checked.

 

[komatsuvarna]

I had a flat top non redlight non decomp mahle 066. It was at 97-119-80 stock.

I have an 066 jug that came off a red light and I have a newer 660 jug but no crankcases to check numbers...plus my "degree wheel" is pretty cheesy and I don't think I'd trust it...can I port map the cylinders some how to come up with anything to add here?

Bring em on over Ted, just ordered a new degree wheel should be here in a day or so

Cool...I'd be happy to...I'll bring my homemade sheet metal wheel and you can mock it. You got a spare crankcase? I was also thinkin about the variance in piston height that you found...how bad would that affect port timing?

I still have the jug off my 066 so we could check all three on there.

What are ideal numbers for an 066? Is it personal preference, or is there one set of numbers everyone aims at?

So, where are the 066 jugs with lower exhaust?

 

[fastLeo151]

I have a 066 ks jug sitting on my 064 but its already been ported.

What do you think of those numbers brad? Are you sayin that exhaust is too high?

 

[blsnelling]

I've heard over the last few years that non-decomp 066 jugs have lower exhaust, or maybe it was Red Light 066s. I'm not saying they don't exist. I'm just saying that we're not seeing them here. The one I have certainly does not.

 

[mdavlee]

98 is the lowest exhaust I remember. It was a non decomp mahle.

 

[Mastermind]

98 is the lowest I've seen.

That better than the 95 I've seen in some new jugs. lol

 

[Deets066]

Still trying to figure out what are desireable numbers for an 066?

 

[fastLeo151]

What are you getting them to after machine work?
