Title: McCULLOCH DOUBLE EAGLE 50 Titan 50
Post by: Cut4fun on February 27, 2012, 01:35:31 pm
This seems like a interesting Mac in 50.9cc.  3.1ci legal for Chardon Al  ;). Cylinder I looked at in pic was open port and bolt on.

Manufactured in Italian McCulloch factory 84-88

I've never seen one myself .Fact the only Italian made Mac I've ever seen is the Titan 70 I own .

I think McCulloch might have resorted to rethinking the designs of the saws around early 90's perhaps .They were already in a downward nose dive and this was probabley a last ditch and feeble attempt to revive a once flourishing company .

This one has been under my bench for a couple years now.  Interesting design and an even more interesting job to change lines.

Interesting indeed .Those large open transfers are kind of like a Stihl 20T .Larger size of course .

I'd imagine the hemi domed piston is to sweep the top of the cylinder on transfer .

It may be.  The comb chamber is machined as the 57 is.  Build quality is top notch on both this saw and the 57.  Unfortunately, coil issues and the fuel/oil line routing plagued them.

Can you show or tell me more on the 2 issues? Why is the fuel line a  :o :o :o :o and are the coils just faulty and unreliable?

Coils are a known weak point.  Most of the saws I've come across do not have many hours on them with weak/no spark.  May have had a dozen of these saws over the last couple years and two have had functional coils.  As for the lines, they are not as bad as the 57.  You have to either remove the tank or split it away from the case to replace the lines.  Limited space and multiple elbows make it a fun job.

Good runners when all is sorted out though....

There's a couple on flea bay .Some cheap ,some they are very proud of .

I thought about it but I have my mind set on an 026 for a 3 cube cookie cutter if I ever get around to it .

Shucks I know next to nothing about these Italian Macs .I'm not saying I'm an expert on Stihls but do know a little bit or at least enough to be comfortable souping them up .

hi guys,came here searching for fuel line size  I have 3 of these plus a titan 57 that a lot of parts swap over from but yes coils are a problem,It is hard to see where the fuel lines run  and the one I need to put lines into now have crumbled away leaving some springs and crumbled black hose.I would gratefully take any suggestions on this job,as I dont want to fiddle with the other 2 while they still run they are pigs to start and do need carb kits .
But I will fiddle with this one firstI came here for a look and registered when this site first opened there wasn't much here then and tonight is my first visit back in a long time thanks to a google search link that I came across while looking for the right fuel linbe size.
I was blown away there is enough reading here to keep me happy all winter congratulations it's great :) :) :)

Pete

I have pics on another laptop.  Will post them later today.  I've been talked into doing this job again (50 and 57) so I will better document it.


Also, looking for usable 50 pistons if anyone has a source or parts saw....

thanks pics of the job would be great,these are good firewood cutters with a 16 inch bar on them ,but number 3 was bought with no spark tried another coil no better put the original back on and fuel down the carb she fires, but as I mentioned the fuel lines are shot. so your pics will be a  big help

Wow Mitch you wasnt kidding about the fuel line pita part early in thread.  Good job on the video info.

Nice vid .Along the same lines I had to fish a new line on the Titan 70 and it was somewhat a pain in the buttocks as well .Worse today was a fuel line for a 2100 Huskey but that belongs in  a different sub topic of the forum ,

Thank you very much for taking the time to make the video as stated way better than pics,just getting the correct fuel line was worth it.The pressure fitting you describe is it along the lines of a piece of fuel line with a setscrew in it,,I am not looking forward to this as once I have done one and it works I gotta do 2 more.As the hard starting I am now attributing to fuel lines,so may as well rering the other 2 while I am at it they dont have as much compression as the first to be fixed cheers and thanks

Oil feed line on the right.  When putting the tank on make sure this line goes over all others and right up against the intake boot....this is the easiest one to pinch.  Line on the left is the impulse

This is the exact configuration for the 50 although this is a 57.  I eliminated the thumb oiler on this saw due to the plunger not functioning anyway.  Would recommend doing this on all 57's......makes the job WAY easier and it oils plenty without.

just put this up as I remember someone looking for pistons, (mewba) If I was  a lot closer I would buy them just for the coils

Hello everyone! I'm having problems with my Double eagle 50... When I move the saw it throtles by itself or it chokes... I changed the whole fuel and oil line and still having the same problem. I don't have an idea what could it be... I can't tune the saw because when I move it eighter it goes wild or it chokes.
Thank you in advance, I am open for any suggestion.  ;)

Maybe the carb is moving around inside the air box?
Title: Re: McCULLOCH DOUBLE EAGLE 50
Post by: EmJay on November 24, 2013, 01:37:47 pm
No, that is not the problem. I think I found the solution... I ordered the carb kit... Maybe when I change the membranes it would work. Now it is useless because I can't tune it. I hope that this kit would solve the problem. Any other suggestion would be great... I will post my results...  :D

Did you ever find the problem?....weak body mounts could be causing a bind or movement in your linkages or a carb boot leak? If it's the intake leaking be careful not to lean it out and destroy the saw...I'm not familiar with these at all but looking at the pics from before these could be issues...Also does this saw use an impulse line?

When you changed the fuel lines did you replace them with the original internal springs,first replacement I omitted the springs and kinked the lines Just a thought
