Have you tried an hd2 air filter and a dual port muffler cover yet ?

Haha just swallowed me chew

Mike,

Do you ever get up this way? I'm working insane hours still but I'd take a peek at it if you wanted.

Appreciate the offer, and will keep it in mind, but Tax Season has started, and these things will have to go on the back burner.

Not yet, but I got things on order, including a carb, coil and vac/pressure tester.

Tax Season has started so my time is very limited, but I will keep you guys posted.

Just a little update, started working on it late today (had lots of other thing to take care of), the New OEM 460 pistons do not have notable machine marks, and the new & old pistons both measure the exact same diameter (2.35), so I think the old piston was just fine, but I will use the new piston and keep the old P&C as a set.

can you take a side by side pic. i am currently working on a 460 as well.

Did you double check your wires going to the kill switch? I had a few spots where the insulation was worn off the kill switch wire causing problems.

 

[VinceGU05]

Sounds like the timing is way off. I don't know how.

had a flywheel shear a key once.. became a *b-word to start.. but wouldnt.. give away was it backfiring thru the carb.

i got a 460 on the bench will double check the carby choke postions and report back.

Now I understand.
Steady as she goes. You are already well tooled, don't need it now. Make this an adventure. These guys have your backside.

So busy right now it is hard to find time to eat.

I take the plug out, reconnect the coil wire, take a wire w/alligator clips on both ends, attach one end to the bottom of the plug and the other end to the engine block, go to a dimly lit room, and pull.

I spoke to someone today who told me that sometimes the coils mess up on their timing, so just because it is producing a spark does not mean it is still good. This could explain a lot!

Mike, get a plug, break off the strap so the spark has to jump from the center to the outer metal. This will tell you if you have strong spark.

Weak spark can jump the gap with the strap attached.

Only a good strong spark will jump the gap on a plug with the strap removed

Did you put a new decompression valve in it? It was missing when you bought the saw. They won't run if that hole is not plugged.

 

[MustangMike]

Yes, the compression feels very good.

 

[drf256]

I'm sure it does

 

[VinceGU05]

This how the fast idle looks with regards to the butterflies.

 

[VinceGU05]
