What's on your bench today?

[GardenKit]

Am I busy....seems the local dealers am making it very easy for me

 

I might send all my filthy, oily, gummy , dusty saws your way Steve:sneaky2: I hate the bloody things. Oily sawdust all over me, all over the workshop and all over the nice shiny clean mowers I have serviced, and they take so long to do.

 

Glad its going well for you mate. I seem to remember you telling me you wanted a 3 day week?

 

Its been 7 days a week here for the last month or 6 weeks, mostly mowers and ride ons, but also more 2T than ever before.

Mmmm, and I remember your response, seems you were right, just a flood of work that keeps coming:001_rolleyes: can't complain though:thumbup:

These big saws can nip up slightly and then the rings can free making some compression but when they run over the small aluminium transfer deposit on the cylinder, compression drops and knocks the performance.

 

Best to stop using it as in extreme cases, the aluminium transfer is scrapped off and can end up I the main bearings knocking them out.

 

These saws have a one way valve in the crank that expels petrol/oil vapour on the clutch needle bearing but if it fails on vacuum, could cause issues.

 

I would pressure and vac check it plus check over the fuel system to make sure all is good if it has lightly seized and new parts are fitted!

 

Just to check will it pressure up if it has a 1 way valve as you say

I can't remember the saw etc but there are two tests to be carried out on the crankcase. In normal running the cases see both vacuum and pressure and this is why you test for both. Splits show up more under pressure but seals can fail on one test and be perfect on the other.

 

The testing you can do depends on the equipment you have.

Should of said husky 3120xp.

Ah 3120, that makes sense now- all you do is pull the clutch off and stick your finger over the hole under the needle bearing - this seals the valve for the pressure check. It should seal on vacuum.

Well my trusty 372 died today. It suddenly just died and on trying to restart it found it had lost considerable compression. Took off the muff, no scoring, plug colour looks like it's been running rich so took the pot off and the piston ring seems stuck in and these marks on the side of the piston

Maybe something got in there? Air filter not in the best shape

So can I just smooth the rough edges off and fit a new ring?

I was planning to send it to spud after I get my jonsered back but I could do with it next week

Main bearing cage breaking up would be my guess.

You cannot just dress that piston and put back in, somthing serious is going on down below, the cylinder must be pretty bad as well?
