661 problems

[laslabjohn]

Hi fellas I just acquired a very nice 661R would not run, has great compression and fire. But when I go to start it it will pop one time and that's it. I changed solenoid checked spark screen. Any suggestions?

If you dump a little gas in the carb will it rev? Trying to point to carb or spark

I'll trade you a very strong ported 066 for it

If not ....................

I've seen bad wiring connections
Does it have the 4700 or the 4701 coil
Have you determined if it is spark or fuel causing this issue

 

[laslabjohn]

I will go dump gas in and see. And yes it has the 4700. And I know it's getting spark and fuel

 

[laslabjohn]

No go on gas in carb. And it's a 4700c carb. I put my tester on iT but it mite be firing in the wrong sequence

Got a 660 carb to throw on really quick to isolate if the 661 carb is the issue?

 

[laslabjohn]

Will it even try to run with a regular carb.

 

[mdavlee]

Yes it will run. Just leave the solenoid hooked up. Is it the one from AS?

I would check continuity of plugs and wires leaving main coil up to the coil
and solenoid at the carb.

Are you sure that the key in the flywheel is ok ??

 

[laslabjohn]

I will check them, I pulled fly wheel everything is good there

Change the coil. The primary wiring will let it pop, but if the secondary wiring is messed up it will not run. This was the problem that drove me crazy with 044#2. I was so sure it was a fuel problem I changed the carb and everything else before I did the coil, which solved the problem.

Did you check the compression with a gauge? Did you pull the muffler?

I'll send you the updated coil.

Wow Thank You Jason!!!!

Yes I did. All is great

Yes I did. All is great

I'll get your saw,parts and coil out in the morning. Been making hay all week and haven't had time to do anything saw related. BTW your 064 is a mean sob!

 

[jmssaws]

You need to get it lined out so I can trade you out of it.

I agree. Lol

Hell yea it is, you built it. I haven't seen a 064 yet that you built that wasn't.
