Morning fellas. My red ford is alive again, new o2 sensor and new cables and it whips right over and ran last night for 25 min with not so much as a twitch at idle! Gonna pull the throttle body and clean then replace a half mile of powdered vacuum lines! 51° here have a good day all!
 
More like on idle speed using my Dremmel with a stone counter-rotating.

Heat to melt the braze would likely kill the crank seal.
but they had to heat it to braze it. hmmm. musta used a heat sink somehow.
i'm thinking there musta been something wrong with the threads for the farmer to go to brazing.
 
Mornin' all. Busy weekend through here all the way through yesterday. You boys sure have been chatty during my absence!

I made a trip to my favorite saw shop yesterday and came home with a couple of little goodies. I'll try to post some pics tonight... ;)
 
Homelite XL 12 on the bench right now... Will run on prime... And full throttle, but no idle...
Anyone have quick words of advice before I proceed???
It will no doubt need fuel line and carb kit... How does this model derive it's impulse?

You, my friend, are an early riser.

What a beautiful day! I get to ride my bike to Shawnee and pick up a 30" wide concrete float. My wife and son are well, and it is nice to wake up next to a 5 month old smiling up at me. Life is good. I hope to put the new carb on my MS200 rear handle later on today. Saws are running well, bike and car the same, we are all healthy, life is good. Hope everyone does well today.

Matt these are reed valve saws, check the carb mount screws and make sure they are tight before you pull the carb.

Yup, threads are likly bad or they lost the l.h. metric nut. Not easy to strip the threads on a hardened crank but turning the nut in the wrong direction can easily strip the nut.

I can understand not wanting to make a twenty mile trip to the nearest hardware store.

My local Ace has L.H. metric nuts on hand. Also, push nuts, roll pins, snap rings etc. Half mile from here in mid-town.
 
Gritz in a couple of months the charity cuts will be starting back up & hopefully you will have the opportunity to participate & meet some of unique folks on this site. I'm about a hour east of you on the other side of Clinton.

Workshop is our coordinator for most of the Springfield area charity cuts & Sam-tip & wife have ones on the east side of Des Moinse, Iowa at Waukee.

Will do... I will try and get it to fire on it's own tonight after letting the carb sit all day with fresh mix in it....
The high jet will tune, and i can keep it running over half throttle.. But as soon as you let it idle down, there's no bringing it back...
Ya gotta prime it..
I been needing to dig into one of these reed valve motors to see what makes em' tick anyway I guess...
Any thoughts as to why the carb would pull fuel at 3/4 to full throttle but not at idle?

That sounds like the low side has some trash / obstruction / old, varnished fuel in it. The fresh fuel mix may work for ya, but it's a "Hail Mary" play. If you're gonna keep it, might as well tear it town and give it a rebuild with some new fuel lines, etc.
If you're giving it to your brother-in-law, leave it as is ... :buttkick: Of course, that's just my opinion.

It WORKED! Reduced the bead enuff to twist off the nut.

About time someone changed this! Evilbay seller is going to get a less than steller rating from me.

Nice work! Are the crank threads going to be usable?

That sprocket looked like it still had some life in it. o_O Are you sure you're gonna change it? :)
 
It's been a while, but don't the XL12's have an impulse hole in the casting where the carb mounts up at? Seems to me they do and if the gasket is put on backwards it will cover up the hole, or the whole gets blocked with crud. Just going from memory here, so not really clear. Also, seems like they will pull fuel at wide open just from the Venturi vacuum.

It's for a neighbor... I figured on a rebuild kit anyway... But if the low side orifice had blockage, I've never had much luck clearing the passages...

I'll check what Jim mentioned, then proceed.. I'm thinking you may be right on the location of the impulse hole.. I will find out this evening.
I'm gonna order a rebuild kit...
I have washed my hands of the local saw shop for good as of this morning...
The owner finally reached my last nerve...

On clearing passages - do you have an ultrasonic cleaner? I've had them work wonders.

On the local saw shop - do you care to elaborate? It must be something beyond the normal level of stupidity.
