Gravedigger's 660

[Gravedigger]

Yes I've been called Gravedigger before there was a monster truck. I filled in graves from 7th to twelfth grade and I'm 54 years old.

Ordered today

I'm not going to compete but want build a reliable saw to occasionally mill. With so many threads going I couldn't resist.

Any thing I should do to help it be reliable please let me know.

The Chinese fuel hose, wrist pin bearing, and oil worm gear should be replaced with oem. There may be other things you'll question along the way, but these are the commonly replaced parts

I agree with @huskihl and would add chain tensioner, intake boot, and spark plug. Welcome to the site brother enjoy!

I remember reading something about the compression release being bad.... As in, if the plastic falls off or melts the rest of the valve falls into the cylinder....
Are the valves in these kit "that one"???

I dunno I plugged mine. If I was going to use a decomp I'd go oem

I've seen it happen to others. Never to me personally. I'd keep an eye on it for sure

Is there a source for the OEM parts?

i would say wrist pin bearing and circlips are MOST important, both fail at a higher rate than the other stuff mentioned and are cheap to buy OEM and harder to swap out later
decomp plug is my preference unless it is a build that needs a decompression valve and then i would prefer the aftermarket husky valve, the oem big husky valve, the oem 880 valve and the oem 066 valve in that order as a replacement to the AM 066 valve
i plan to put up a listing for oem clips and piston pin bearing this weekend for buildoff guys, unless i take too many naps (always a possibility)

Got tied up working on my 064. Need to find a carb to replace a bing that needs to be rebuilt. Walboro zama or others . No fuel compensator

I'm running a walbro wj-76 on my Chinese 660, which I believe was one possible OEM 064 carb.
Any chance your Chinese carb will fit the 064?

 

[Gravedigger]

The bottom of the transfer port is a "little" rough.

Exhaust looks good.

Intake might have some issues

Case bearings feel good but on the flywheel side metal between seal and bearing.

I'm already have new seals so I think it's a non issue.
