Saw builds

@huskihl, I was asking what they were boring when coming across idle issues etc. I was unsure if issues were arising from people machining the barrel or from boring the Jets.

Without the divider it will never be able to provide enough fuel. The low pressure signal would be weaker than it is calibrated for.

The divider is not an airflow restriction in any way though.

That's why I'm here. If it ain't gonna work, I need to figger out which hole(s) to enlarge

I believe @jmssaws was referring to boring the bore/venturi. If I was a guessing man, I'd say @Mastermind's scrap pile contains a few of each method.

I'd have to be whacked out on crack to seriously consider it. Lol

I tried both ways on the RWJ. Matt's runs ok but it's temperamental bastard. I've give up on them. I'll use a Wj116 or 118 and it's not been near as picky.

I don't care for the idle or transition qualities...

What did you send me for the solo? 118?

RWJ

 

[mdavlee]

RWJ

Yeah they're a pain to keep tuned.

 

[Deets066]

Tillotson 296

Haha, I never even looked just fit it up.

It's worked perfect and holds a great tune

I kept the 116 when you said tilly over walbro

 

[Deets066]

I'd take a Tilly any day

 

[mdavlee]

Yep. I've pulled several out of boxes of parts and they're fine. A walbro I look at wrong and they won't work

 

[jmssaws]

I tried one today on a 064/066,new out of the box with the divider and without,it started and idles good and tuned easily but at 2 and 3 turns out.
Once warm to get it to stop lean surging at a idle it's so fat it instantly dies when you hit the throttle,ran ok wfo cutting but you could screw both needles out of the carb and it still be starving after a 20 second cut.
Put the wj6 back on and all is well.

I've tried one on a 066 7900 372 with the some results.
I'm done with them.
They may as well be a HD

I guarantee you I have 20+ HD carbs for a 372 or 460 and can't make any of them act like a zama.
I can't fix them, there either good or bad and there's nothing I can do about it.

I'm going to put several in an ultrasonic and see if that helps
