Carburetors - Custom or High Performance Installations

[jmester]

You can see in the first pic where I crushed the horn down with out any inserts in it. Then in turn it mushroomed out the insert for there was no support. Other wise I like it better then having longer studs made.

If you look close you can see the gap. That is why I use clear silicone.

Would you be willing to make a couple of those for me? Looks good and should work well with the 394/395 filter horn.

Got the set up done on my 661 today. Have the WJ-76 installed with a .68 fixed jet. Still waiting on the euro coil and correct carb grommet. Think it turned out well. Will be interested to see how it runs.

I hope it lives up to what others have said. I will keep you posted may even shoot a video.

Have any time to run that 661? @jmester

 

[jmester]

Not yet. Still waiting for the ignition modules. The guy that was getting them for me has been diagnosed with cancer and in the hospital and has not been able to get them shipped.
Found another guy to help me out. In the mean time and that stuff is on the way. Will keep you posted.

Finally got the euro coil and correct carb grommet. Should have time to tune it tomorrow. I am looking forward to cutting some timber Monday with it.

Evidently that coil is limited to 13.5k. I just found this out yesterday

 

[jmester]

I saw your post about that. That's should be fine for me any way I usually set them on the high side at 13,200. I like the fuel. I think I saw that moparmyway's euro coil went to like 13,800. Maybe it was the 4701 coil.

 

[jmester]

Stihl they always have to limit you some how.

Read down the page he says over 14,000. Not sure what is going on. But maybe I missed something.

He sent me that same coil to play with. I never got a reading above 13.3k. The manual in my thread about the different coils shows a page that says set as close to 13.5k and then an 1/8 turn leaner past the limiter.

How many different mount styles does stihl really have maybe three or four? Just the mount not the hole or the boot size. Barring top handles and TS's just saws.

Run that 661 pretty good today. Seems to do good.
