Homelite Chainsaws

I have several parts saws still in my garage, I will investigate those before I buy anything.

Found out today the coil is also dead. I will see if I can remove the spark plug wire and determine if it is the coil or just the wire.

Next week...

If you still talking about that SW66, I've found the coils and ignitions are pretty much the same. Any of those generation will swap ignitions. They are even the same as the 900 series monsters along with the CCW flywheels.

I just picked up this bar , I haven't seen very many with the 3 stars on each side
Of the homelite logo. It's 36" .63 404

Any chance you’d sell that bar?

got the SXL 925 to start and run for the first time, as long as I keep feathering the throttle. will not idle on its own, just dies no matter where I adjust the low and hi screws if I stop feathering it. has a hesitation. idle screw is adjusted plenty high for adjusting the carb screws. carb has been kitted and carb holds pressure. guess I need to pressure and vacuum test the crankcase next.

did the pressure and vacuum tests. no drop and held a vacuum all during lunch. as I said before, the carb also holds pressure and vacuum. have taken the carb apart again, all gaskets and diaphragms are in the correct order. tried different spark plugs. just do not get it. fires but won't idle. runs as long as I keep feathering the trigger. take my finger off the throttle and it goes blah and dies. anyone have any ideas?

Inlet needle height is good? New fuel hoses? Vents are working good? Which carb is in that?

 

[flatsfisher]

does this look like the correct high speed power jet? does this jet have a one-way valve in it?

inlet needle height is correct, new fuel filter, all new hoses including tank vent. tank vent is working. carb has fuel in it every time I take it apart. carb is a Tillotson HS 151B.

IPL calls this brass piece a check valve. drove it out and did the blow and suck test with a pc of fuel line. no check valve in it so I probed it with a tiny torch cleaner and just a hole going all the way thru. if it had a check valve disc inside it is gone now. would this cause it to die on idle?

 

[flatsfisher]

that thing just may be the problem. found this video by West Coast Chainsaws on YouTube.

ordered a couple of different "check valves", one stock, same as what I took out but NOS, one OEM discussed in a thread I read. while I'm waiting, took care of the only rust on this beautiful chainsaw.

Peruse this.

I'm following with interest. My SXL-925 had/has a finicky carburetor. I need to pull it out and run it. Good luck, Max.

Without the check valve it is likely the engine is flooding at idle due to pressure on the wet side pushing fuel through the idle ports.

I had one of those carbs on a 922. It’s a fixed jet basically. You can pretty much close the hi jet off. Forget what factory setting is. 1/2 to 3/4 I’m guessing. I could not get it to tune at all. Pretty much exactly what you were describing. I messed around for a long time then just swapped it out for an older XL700 carb. Worked perfect after that.

yes, apparently, I have what is referred to in another old thread I found as the "dreaded" Tillotson 151B. thanks. I also read an old thread from House of Homelite where Leon said that he had a number of new nozzles in stock (at the time) and he could see thru them all, no check valves. thank you for the link.

agree, but I was reading an old House of Homelite thread last night where Leon said that none of the new nozzles he had in stock at that time appeared to have check valves as he could see right thru them. I've ordered 2 nozzles from ebay, a 69793, which is listed in the IPL I pasted above, which is for the HS 151B carb and also ordered a 65493 nozzle which the seller says was for the 900 and 920 models.

I have 2 NOS nozzles for the PM1000 Tillotson carb, but they are longer and a larger diameter and do not have the jet hole in the top.

 

[flatsfisher]

the question still remains, as Modified Mark said in the thread cbfarmall linked above, what changed to make these apparently non check valve nozzles fail when they were working previously? and why did Tillotson label them as check valves when they are wide open?

BTW, I did know about the High screw needing to be run lean because of the nozzle, had read that somewhere. I have had the high needle at 1/2 out but have not tried it completely closed, or almost closed.

 

[xl130]

Good luck with that carb. I hope you can get it ti run right. If you decide to throw it out the window let me know. I may have an extra fully adjustable carb, they work much better IMO.
