Newbie, with a bunch of old Husky L65's

[chuckwood]

Chuckwood, Is your saw one of the Tomos/yugoslavian saws? Ours with the sealing problem was.

My saw is made in Sweden. I'll check the carb to see if it is like yours. If so, I'm thinking about filling that area in carefully with JB weld. I like these old Huskies, I've accumulated a lot of spare parts over the years when I find (every now and then) a really good deal on a parts saw. I'd like to build another L77 out of my parts pile but I'm having no luck so far finding the right size piston. Somebody on ebay is offering a brand new L77 for around 800 bucks - he's really proud of his - if he comes down to 300, I might bid on it.

I just cut up about a cord of wood, the saw with the bigger carb just screams through it, the other saw did have a plug in the crankcase pilot, which I cleared out, but I still can't richen it enough. I also found that a 32:1 oil mix is still a pretty lean mix for a ported out saw.. I put a little more oil in the tank directly and you just see a little haze at the end of the woodpile now.. Makes better power like that. Unfortunately my wood has a lot of dirt stuck in the bark from skidding, so I've been doing a lot of sharpening

Hey Rx7 man, nice huskys!

I like 7's too, they're a great prescription for a speed problem

I had a S4 FC, limited slip rear, yeah, they're ALOT of fun on dirt roads
Actively looking for my next project 7...

 

[Rx7man]

I had at least one of each, my favourite was a ported out 12A in an '85 FB.. powerband from 5000-80000 was crazy fun... Though my '93 bridgeport turbo with 400rwhp was fun too, but I just couldn't beat the snot out of it on dirt roads.. Sold them all now.. so I painted my '94 dodge diesel dually the color of my '93 Rx7 (Montego blue), and put a new (yes, ported and cammed) engine in it this spring... it's no slouch with somewhere in the 350hp range. Gets better mileage and top end power now.
I actually still have 1 Rx7... an '85 I was working on making into an ice racer, but then they cancelled the local ice races they year I started on it.. . That one has a brand new streetported 12A with a eaton M90 supercharger running 6 PSI, I figure about 250 HP... Kinda had some fueling problems with it.. Have a new standalone ECU and injectors, but it needs a lot of other work to it too... thing sounded pretty raunchy with a flowmaster.. like a jackhammer on a manhole cover!

I guess if it's got ports... I'm going to hog them out!.. haven't had something that didn't perform better after yet

 

[Rx7man]

OK, it took a little while, but I got a video of the saw with the bigger carb cutting through a piece of dry fir

What do you all think? It was 24 seconds to cut through it.

I think it's getting a little more oil than it needs, but I'm trying to find the right mix for it yet.. I think about a 24:1 for heavy work, and 32:1 for light work is what its going to be running

 

[tpope]

Sweet. I run 32:1 in my saws. Seems to be enough for the older ones and the newer hotrods...
You need to check out the 288s... They are a step up on power and 2 steps up on antivibes. And 3 or more times as addictive...

 

[Rx7man]

I'm a cheap bastard, I'm going to run these pretty much til the day I die, or til I can't find parts and don't have spares

where are you in the interior ? Im in Peachland and have lots of parts for the 65s and 77 good p&cs ect
The 480 cd is the end result of the l77s I have the tilly hs 123 s on mine but you could probably move up to
a 205 hs and same configuration

 

[griffonks]

welcome, my entry.

I'm wanting to build another L77 out of my parts pile, and I have everything to do it except for a piston and a spark plug wire. The only plug wires I have are for L65's, and they are too short - I could probably figure out a way around that, but the piston is another issue. Pistons and cylinders for these saws come in slightly different sizes, ranging from "A" to "D", and they must be matched. My only L77 cylinder has a "D" stamped on it and I've not found any "D" pistons so far. I got real lucky with my first L77, I found a new matched piston and cylinder on ebay. I'm still watching and waiting for another one. The L77's have the same pistons and cylinders that the 180 to 480 series have, but these saws seem even more rare, not much on ebay for them either.

 

[Termite]

The L65 where very popular around this area. I bought mine new in 1978 as did my neighbor. Around $500 I think. Our Sheriff elect has two and is dropping one of for repair. An L65 was my only saw until 1991 when I bought a Husy41. It was a POS. in comparison.

 

[67L36Driver]

There are a couple piston/cylinder sets for 65's on eBay but no 77's.

 

[TIMBERTRON]

i know a guy in great falls mt that has a 65l that runs great and is looking to sell might be able to get it from him for 70-80 bucks great saw i like the ones ive worked on
by the way welcome to AS

 

[Rx7man]

Timbertron, that saw looks to be in nice shape, can't read what the compression tester says though.

 

[Rx7man]

Where is the size stamp on the cylinder?

 

[tpope]

Middle of the top,

 

[Rx7man]

Well, I picked up the parts saw from my neighbor, gave him $20 for a stocking stuffer for his grandkids, got the saw home and gave it a look over, it's been really sun baked, chain side cover is missing, and carb cover is in real bad shape, but the saw has hardly seen any use at all.. with no oil and not having been run it had 130 PSI compression, a squirt of oil brought it to 150 psi. Took the carb apart, the side toward the engine is factory clean and shiny, and its internals were all in mint shape, no play in the shafts, and no wear in the linkages.. Sprocket and clutch are perfect as well. Piston (from the intake side) is immaculate and shiny.. has a working kill switch (rarity!), good air filter... Had no spark, but a quick filing of the points and it had good hot spark again... I don't doubt this saw will run great, might leave this one unported, at least for now...
The fuel tank needs a heck of a cleaning though, the paint has peeled off and its gummed like you can't imagine.. fuel line doesn't even exist anymore. I poured some gunwash (for paint guns) into the tank and I'll let it soften everything up, then I might pour some 2 part urethane paint in and shake it around, then drain it out and that ought to prevent too much crap from getting into the fuel in the future

 

[Rx7man]

Took the head cover off, it's also a C sized cylinder (seems to be very common), and the top of the head doesn't look like it ever got hot. If it just had the right side cover and carb cover this would be a perfect saw, but I think it was well worth $20 anyhow. I'll pop the head off tonight and maybe remove the base gasket if squish allows.

 

[67L36Driver]

A new ring would be a good investment at this stage. And, clean the ring land(s).

 

[Rx7man]

Just took the top off, it doesn't even have carbon in the transfer ports, not the slightest trace of scuffing on the piston at the exhaust side either.. Some other telltale signs of high use are the air cleaner screw-nuts and chain tensioner screw are all in nice shape and haven't had the screwdriver groove rounded off.
I don't think I'll bother replacing the ring, it is certain to be good, but I'll clean the groove out. it's only an hour job to put a new ring in.. However, I may buy a couple spare rings while I can still get them!

While I was fixing the points on this saw I noticed you can change the timing without changing point gap.. you can rotate the whole plate.. something I'm sure would help on the ported ones. I'm sure I had noticed this before but had forgotten.
