A question for you - The XL 400 I have uses twice the gas as my 041 to do the same amount of work - I can't lean it out anymore without it starting to miss, the 041 I can't richen without it bogging down. What gives? The 041 has a 1.31 pint gas tank, I can't find a spec on the XL 400. I don't get a fouled plug, it starts & runs good. Lacks power though, I feel. The 041 [3.7 c.i.] will out cut the XL [4.0 c.i.] any day of the week. Will compression [or lack of] cause this? I'd throw a set of rings in it if anyone thought It would help. I know gas is cheap again [ha ha] but this saw really seems to eat it. Help?

It isn't hard to do a compression test unless you don't have access to a gauge so do one and see what it reads. What about a bad crankshaft seal? If the seal on the clutch side was bad, it could leak some of the crankcase charge and you'd never notice it because of all the bar oil and sawdust on that side of the saw. If the ignition side one leaks, you can't keep the points clean.

The local Tru Value probably has a gauge, I'll check it out. RBW, a pretty decent one just sold on ebay for about 210.00 even had the manual. Thats the highest I've seen one go.

I listed a XL 400 for parts on Ebay last night. It has a scored piston and cylinder. It was the first one I had ever seen around here. A guy traded it to me for fixing his Super 2 that he had torn down and then didn't know how it went back together. He said the XL 400 ran good the last time he used it 15 years ago.(yeah right). I don't think I'm going to make out on that deal. I guess I'll see

I've got it on my watch list, I'd like to have one for parts - But, the scored up p & c are a real turnoff. Thanks for being honest about it, a lot of sellers wouldn't!

It probably wouldn't be on Ebay if it didn't have a scored P/C. I should have been more careful when I cleaned it off. The air took off a bunch of paint. It pays to be honest when selling on Ebay. |

Stopped by the local TruValue with my 400 today, the comp. gage had was the kind you hold onto the plug hole, no threads. Are they all like that? Seems kind of crude. Anyway, with me holding the saw & pulling the cord & him holding the gage the best reading we could get was 75 lbs. From what I've read, thats kind of low. Not sure how accurate the test was, what with the way the gage works?

No, that's a cheapy, don't buy it.
The ones that you want have a threaded and o-ringed end, plus they have a shrader valve in the end. They usually come with adapters for different size spark plug holes. Most auto parts stores will have them. CSW

OK, I admit that I got this one. I can't resist nice originals. There were crappy pics and no mention whether it ran or not. I took the chance and of course it ran like a good ol' Homelite. Worth every dime to me. I added the NOS bar and is it a beauty.     |

Nice one jpw - Is it going to be a 'user' or a 'shelf sitter'?

That 500 is a great looking saw! With 74 cc's of power, I bet that it can hold its own. I think I may have to search for one of those. Although , I'm pretty sure they did not make very many. I've got nothing but time! Eventually one will show up.

I agree, a very good looking saw, I guess I've never even seen a 500 up till now, because I was under the impression that they were styled like the 400's but that looks more like the red/white/green xl autos. Time is deffinitely a requirement when looking for some of homelite's rarer saws. |

Tell me about it. I about threw my arm out trying to start my 400 without pressing the decomp button. Why is it that certain models have compression like this? My XL Auto does not have the button but starts with a pretty easy pull. My C9 is another arm puller without the decomp button!

What you guys say about the compression on the 400 leads me to believe mine's really lacking there. I can start it pretty easily without using the de-comp. I tore it all apart yesterday pm, waiting for rings now. There's no scoring, just wear that shows. If I can get a good pic. of it I'll post it later.

As long as you have it that far apart you should put seals on both sides of the crankshaft too and make sure the decompression valve seals good. Glad you posted this because the thread was getting side tracked a little.

Zip, About all that can be done with the decompression valve is to make sure it is seating properly. The IPL shows this as a single piece so if there was some doubt about whether or not if was sealing, the best thing to do would be to squirt some carbon free in it and blow it out.
