Wouldn't even need a grommet to seal the fuel line to the tank.

Forgot just how big these tilly's are. Hda is the biggest I've used in a while.

Clean saw. Really similar to the 670 except Air filter, Chain brake, cover, front tensioner, and color. are the main visible ques.



Small ex port, but look at the dropped floor...



This one will clean up real nice.



Might dig back into this one after a std port job. Be really easy to adapt a large carb/boot, not planning to at this time.



This has me kind of baffled. No base gasket/ sealer at all.. nothing appears to be touched... based on the corrosion on the jug bolts. Wonder if it was like that since new? Still had plenty of comp to run and a new tygon fuel line.



Nice little chunk missing.



before



after



dual port.



Intake



Beefy connecting rod.

Sq .048
In 74, Ex 103, Tr 122.

This one is getting a 268 piston. More than likely add some bridges on the intake side, rather small tunnel,

Have to see what numbers look like with the 268 piston but I would like to see 77 101 123...
The 670's and 8000's came from the factory with no base gasket.

670's for sure had a gasket.

Now the 6700, 8000 may be gasketless. I just find that hard to believe. But I guess anything is possible. This is some of the best machine work I have seen on any case/cylinder.
They just use sealer on the case halfs.

The 4000, 4500 and early 4600's didn't use a base gasket either, though I don't own or ever have owned a 5500, it likely didn't use one as well.....

Think I'm being a little too timid, with my hacking...

55% or less on the widths. I always hear or 65% being a good target. Man that is getting out there...

Exhaust flange /bolts are roughly 63% on this one lol.

I think less than 60 you are leaving a good bit on the table

Ok, our resident midget pig informed me I was measuring wrong... when I get back I will perform the correct width measurement's.

Have just been going stright across. Not with the curve...

But most of the time, on width I just take out the factory bevel.
