WANT MORE OUT OF SHINDAIWA 757

[peter92]

Yes sir. You want to take it off the side that will allow you to advance the flywheel which would mean turning it counterclockwise.

thanks for that

 

[peter92]

Pull the flywheel, mark the key with a sharpie while it's in the crank, grab the key with a pair of vise grips at the same depth it was in the crank, now carefully file off .020" of the portion that has the sharpie ink on it. Install, rotate flywheel ahead til it butts up to the key and lock it down.

thanks for that , it wouldn't want more that .020
then is tuning done the same way

Tree monkey would have warned you if the coil is self advancing, so that's likely no worry.

The Shindaiwa coils are self advancing. They retard for easy starting and have an advance curve based on RPM. Filing the key and rotating the flywheel shifts the base timing, as well as the advance curve.

 

[peter92]

is there another cylinder that will fit on the 757 , theres not alot of info out there on these saws , no mods that ive seen

Start small and work up. I think you could go as much as .030 but .010 might be enough. It's something that has to be experimented with.

By no means is ignition timing a magic bullet. I think you'd get more out of a good muffler mod and a proper carb tune.

ok that does make sense , so ill do a muff mod first , i think Josh has some pics on the muff mod as i have done that be fore, seen people just drill holes in the muff but thats not the right way to do it im sure

I don't think so. Four Paws is the man on these Shinny's.

 

[beaglebriar]

You could probably just open up under the deflector some but I don't remember what the 757 muffler looks like.

 

[peter92]

I don't think so. Four Paws is the man on these Shinny's.

yep , been chatting to him , there isnt much out there on the 757,s

757's muffler is a zoo compared to a 575.

what does that mean

 

[beaglebriar]

Must be lots of baffles huh?

 

[peter92]

Must be lots of baffles huh?

hopefully i get to see pics of one being done , that way i can do it properly , and not look like crap

 

[exSW]

Baffles on baffles,bulkheads and tubes. I just boxed it up and sent it to Dunlap.

so you just posted the muff and got him to do it , i like that idea better

 

[exSW]

Yup. Might have tried it myself if I'd had a spare.

 

[peter92]

Yup.

i just gotta find some one over here in Australia now to do me a mod
