Which saw are you working on again?
Its the 038 Super. The one I bought last year. I bought it cheap sort of expecting to need to fix lots of problems...a learner saw....but then with little girl #2 arriving last August I found i had no time. I fixed the immediate problem it had, a destroyed spark plug thread and sealing surface, and got it running but back in the spring it had a wandering idle which i was told meant an air leak. it also had a tendency to spray fuel over my fingers as i squeezed the trigger to restart it...I concluded knackered carb and took a short cut and bought a farmetec bing carb for about £6. Suspecting the AV mounts to be past it I was guessing the intake boot had ether ripped as the saw vibrated excessively, or had also perished...farmetc replacement ordered for £1.50 these had sat around for months but with my fiancee away at her parents with the 2 girls i got to play yesterday.....I had to take the motor off the handle to get to the boot....then i got carried away. I decided to give it a good clean, lots of pics, and hopefully it'll sell a bit better on ebay once rebuilt. however once at the boot it is clearly fine, so...seals are the next obvious leak. I considered reassembling and being an utter git, and just selling as is, passing the problem on, but i just can't do that....too honest....so farmertec flywheel puller, new av mount, pair of seals, a fuel hose, a tank vent hose, and a bit of pipe for the vent on the bing carb that goes to the filter (tillotson carb didn't have it), and a carb kit for the tillotson, I've spent another tenner. Hopefully after all this the saw will run well....and I'll probably think, 'why have i just bought a brand new husky?' but no... I love playing with engines, I'm a chartered engineer, but don't have the time. With shipping from china and then my girls keeping daddy busy it;ll be months before i get to rebuild this (and remembering where everything goes will be a challenge!). I'm drawing a line here though...bearings are staying put....unless they are visually utterly goosed ...even then my want will be to just fit the seals, bolt it together, tune, video it starting and running nicely, stick it on ebay and get most of my sunk cash back.
on the plus side...its turning out to be the learner i wanted.....but please, i've decided that right now i don't need to learn parting the case, driving out dead bearings, sticing new ones in the fridge, and cases in the oven, driving new bearings in, pressing the shaft back in and so on.....I really don't need to learn that. I want to get my giggles running a bigish husky instead.
