I bought a basket case, I didn't know it, but it was priced right. In the process of removing the cylinder I came across one of the oil lines that had some sort hard yellow goo all over it, wh I scraped it away it became obvious that that had glued the fitting on and part of the fitting had broken off in the compression nut. It looks like the rim was trashed and the chain had been eating into the fuel tank cover fr a while, but so far that's all the new issues. The old issues are 30psi presumably causes by a dep score? in the cylinder. This is actually the first piston I have actually seen not in the wild, so I am assuming this one is pretty much toast. The pilot skit measures 2.008 on the outside and 1.802 on the inside if my chinese digital calipers are anywhere near accurate. I have everything bagged and tagged,it ahs the Wico Points and condenser ignition and coil, looks fairly good. I'm pretty sure I'm going to need a cylinder and a piston or piston and ring kit to start with.  20180427_183944 by Al Michaels, on Flickr  20180427_191344 by Al Michaels, on Flickr  20180427_191351 by Al Michaels, on Flickr  20180427_191414 by Al Michaels, on Flickr  20180427_194751 by Al Michaels, on Flickr  20180427_195325 by Al Michaels, on Flickr  20180427_195331 by Al Michaels, on Flickr  20180427_200311 by Al Michaels, on Flickr  20180427_200351 by Al Michaels, on Flickr  20180427_200715 by Al Michaels, on Flickr |

Well, it's dirty alright. But, it does not look all that bad. I will say that I have never seen a torn down saw on such a clean and orderly bench. That is an accomplishment in itself. Nice work.

Well thank you, it's the only way I can work, it must be the German in me. My main concern is the 30psi reading I got, is that cylinder damage enough to get that type of low compression readings? |

From the pictures you posted, I may be going blind but I can't see even remotely enough damaged for a 30PSI reading...seen far worse than that with a much better reading. The piston actually looks pretty good, just some heat marks. On first glance, I'd say both are good enough to use with a new set of rings! |

Piston and cylinder have a couple of good gouges, but I don’t see any on rings. Were the rings stuck? |

That's what has me worried, I'm going to inspect the cylinder again |

Does it have a decompression valve? I got a super EZ that has very low comp, I found that it had a broken decomp valve .

I'm going through each bag/box of parts and cleaning them with solvent. I'll do a tri-sodium phosphate wash and then a soap and water rinse on all parts that get painted. I have 11 items I'm going to replace, plus decals, so far close to 100.00 before shipping. New felt seal and "O"ring on the oil pump, new check valve, new fuel line, plate and pad handle gaskets, handle screw, sprocket rim and bearing, piston, pin, and rings, and cylinder. Adding the paint and clear coat going to be close to 180.00 with paint and decals. I have 25.00 in the saw itself, so I wont feel real bad, since I haven't seen a XL-102 Automatic before and haven't seen many around. While I have it apart, is there a easy way to check the crank seals?  20180428_204850 by Al Michaels, on Flickr  20180428_210856 by Al Michaels, on Flickr  20180428_213251 by Al Michaels, on Flickr  20180428_213237 by Al Michaels, on Flickr  20180428_205947 by Al Michaels, on Flickr |

The seals need to have some drag on the shaft but it is pretty hard to tell if they function properly when disassembled. The only real test is running or a vacuum test, both of which need at least partial assembly. Visual inspection might reveal faults but finding none does not mean seals are good.

When you did compression test, was the saw fully assembled? I just can't see getting only 30psi seeing those pics. If the reeds were out, that would explain it.

No the reeds were in and I cant understand how the compression could be that low. When I was pulling the cord I knew the tester wasn't wrong, no resistance at all. I haven't order parts yey thinking that while cleaning the old parts I can find the issue. It has that one deep score in the cylinder and i found a bad spot on the top edge of the piston, like it had hit metal. It is score in the cylinder deep enough to hang my fingernail on. |

Well there is good news and some not so good news. The good news is when I tested my 35 for compression I got 30psi, same as the XL-102 Auto, hmmmm. I just bought that compression tester a week ago and used it once. I used my hand held push in conical rubber tester and the 35 blew 150psi. So I have to believe the XL-102 had better than 30psi, but with the condition and tearing it apart anyway, I have no qualms about investing in many new parts. The not so good news is when I removed the handle brace it was broken from the damage occurred during shipping. I can deal with that.

Well at least the compression mystery is solved!

Well at least the compression mystery is solved! Yep, but pulling on it didn't make me believe there was anything over 90psi on it anyway, maybe a little less. I was able to order all but 3 of the parts from you, so saved myself from multiple eBay sellers and shipping. With all the parts and including the Pontiac blue, self etching primer, epoxy clear coat, I'm into this saw for 175 including what I paid for it, not including decals, but it will be well worth it. |

Broken screw is Out, I bought a 8.00 set of left hand thread drill bits, a small drill bit, and an easy out, but ended up sharpening a screw and catching a hang nail on the broken screw and backing it out by tapping the sharpened screw with a hammer.  20180430_203611 by Al Michaels, on Flickr  20180430_203655 by Al Michaels, on Flickr |

I'm ready for the last cleaning before paint on the disassembled XL-102 Auto. Solution will be approx 1 ounce of TSP, 1 ounce of Sodium Carbonate, 1 gram of synthetic soap in a liter of distilled water. After a hour soaking I'll brush all the parts with a soft scrubber, then rinse and let dry. In the meantime I acquired another XL-102 Automatic so I know how it goes back together. I've got Joe from Sugar creek working on decals, but while I wait, I'll be seeing about getting the complete Xl-102 auto running. i think I'm going to use lacquer on this so I can match the existing color rather than pick something close; with using the Spray Max two part epoxy I don't think I will have any problems and I think I'll get better adhesion of the paint to the magnesium.  20180511_201727 by Al Michaels, on Flickr  20180511_201739 by Al Michaels, on Flickr |

I used my solution of Sodium Carbonate, Trisodium Phosphate, and synthetic soap and it cleaned the surfaces of oil very good, I sanded all the surfaces and have a couple of bondo patches to do where the chain hit the case, then Zinc Chromate primer. There are two possible paint candidates in lacquer, Duplicolor perfect match BGM0423 (Maui Blue) and Duplicolor engine enamel (DE1616) with ceramic, if neither of these metallics is right, I'll have the paint matched in a quart of lacquer metallic. I just saw a machine you can buy that adds your mixed paint to a aerosol paint can, bet that cost some money. I've used the Preval sprayers with the glass jar under the aerosol, I wouldn't do a whole saw with one. I've ordered the decals and as time allows I'll continue the restoration process. I have about half my summer crop up and doing great, I need to plant another crop now and another two crops in August.  20180514_212411 by Al Michaels, on Flickr  20180514_212423 by Al Michaels, on Flickr  20180514_212439 by Al Michaels, on Flickr  20180514_212443 by Al Michaels, on Flickr  20180514_212451 by Al Michaels, on Flickr  20180514_212455 by Al Michaels, on Flickr |
