I wanted to show a before and after of a weld job on a Poulan 3750 Tim Allen.   The area where the chain adjuster sits was broken out because the clutch cover got tightened down on it.   A lot of the welding was done from the back side.



I had a 330 I bought for parts  like that. I think they put bar on, missed the bar adjuster and pushed it through case when cover was tighten down.  I rednecked it and put the saw back into firewood service.   So far good to go.

Now you know the welding I want to see, is that other TA that had bow saw on it.  Before / After pics pleaseeeeeee   ;D

It is coming I have the saw all tore down and the case split.   All I have to do now is get out to my garage and weld it.

Here is another weld job that I did on a Poulan 3400 clutch cover.   The part that holds the chain adjust in place was broken out.



This is after the welding was done.   The dark areas are JB Weld that I used to fill in some small shallow pitting.


This is how I managed to keep the hole in place for the chain adjuster while I welded it.

I do not remember if I ever showed this weld job that I did on a Husqvarna crankshaft that was broken on the end where the c-clip goes. 





When the welding was completed I duct taped the piston to the counter balance of the crankshaft and then turned it on my lathe to get the groove for the c-clip back to the correct width.

This is the clutch cover on a 306A that is **** where the bucking spike attaches.   This is pretty common and  I have seen it quit a bit.  On the back side you can not see I pressed a nut into the cover so a screw can now be put in to hold the spike in place.

Well I finished up the welding on the 3750 that was pictured above.   There was a gap between the crankcase and clutch cover where someone ground it out to fit a bow bar.   
   
I have been collecting parts for this saw for quit awhile now so I should be good to go and can start cleaning everything up for re-assembly.
