  1. I would imagine that is a compression gauge and not a pressure/vacuum gauge .......different bit of kit!
  2. I traced the air leak and found it venting in one of the cavities behind the flywheel so filled the cavity with epoxy. I did this to Rich Rules 660 a couple of years ago as it had the same issue and it lasted. You can still remove the bolts etc so no issues there. If you have gone through to the oil tank then it will be a difficult fix without splitting the cases and it depends how bad the damage is. Golf pistons are OK but nowadays stick to Meteor pistons and Caber rings when I can.
  3. That's a big version of what I have just posted. You may be able to split the cases and repair with a bit of epoxy, difficult to tell without seeing the damage. Good luck with it!
  4. These young'uns are sooooo clever aren't they, they know so much more than us old farts, don't they:001_rolleyes:
  5. Had an interesting MS660 in recently, another guy had "repaired" the saw and it had gone really bad, funny as he has a BIG following on Facebook! It came to me with a seized (was supposed to be serviced) Chinese top end and a big chunk out of the inlet port....good start:001_rolleyes: I couldn't get hold of a Meteor top end so it was an OEM top end rebuild. I ported the top end before fitting on customers instructions. I pressure checked it and BIG failure. I traced the first leak to damage to the crankcase wall leading in to one of the cavities behind the flywheel. No other option but to seal it with JB weld. Having done this, I removed the cylinder and found a protrusion in to the crankcase cavity so managed to remove it and reckon it was a piece of piston ring driven in to the casting that had damaged it as the metal was ferrous. This was sorted, another check revealed a leaking/split inlet manifold. Got this sorted and then found that there was wear in the throttle linkage messing up the fast idle setting and stopping the saw working. I got this sorted, replaced a number of missing parts and finally fitted a new rim drive....I thought this saw had been serviced:001_rolleyes: There was a load wrong with this saw - God knows what the previous bloke did for his £240 repair bill:001_rolleyes:

    560 woes

    Thanks and always a pleasure. Done quite a number of these saws now and am quite at home working on them. Glad you are liking it:thumbup:

    ms650

    £450-650 depending on bar, chain and overall condition.
  8. Had a mad busy three weeks, a right mix - FS410 X2 with various faults. Keep getting fractured aluminium clutch housing clamps on them and reckon it is the starting method. Had a bevvy of MS200Ts, a rear handle one as well, 357XPs, MS341 with knocked out main bearings, long reach Komatsu, MS650 with a loose cylinder and more!!! Also had my poorly Mordaunt Short 150w sub on the bench.... just stopped working, traced it back to the speaker output wire having a dry joint plus a switch for the notch filter needed cleaning. It is all back together and shifting air nicely now - the wife was astounded how much the cone moves with Led Zep Kashmir at full tilt:thumbup:

    ms650

    British Alcan was the company!

    ms650

    Yes it will fit. Make sure there isn't a residue of black powder on the body of the saw as many 650s were being used by an aluminium processing plant a few years back and most of them were shagged from cutting billets of aluminium. If it is clean and cheap then probably a good bet.
  11. Why don't you just stand it for 24hrs or is the temptation to throw the switch too great:001_rolleyes: All I know is that manufacturers tend to say to leave the unit standing for a while! I would just do that....no point in possibly cocking it up with impatience!

    Clutch

    Bugger, don't know of a song with that in it:thumbdown:

    Clutch

    You know how it is, I love a bit of music...even old Fat Laz:biggrin: Absolute 80s gets me through the day......anyway, how is the Zooming noise? Usually a sign of the clutch needle needing a bit of grease or perhaps a little worn!
  14. That is one persons take on a dual port, cant say if it is any good or not but the autotune will adjust for it!
  15. No porting experience on the 661 to date and can't be sure what is on the table until the piston and cylinder are off. Muffler mods are usually quite effective with autotune models but expect more noise. The autotune is very effective at accommodating tuning mods as well as any air leaks and often protects the engine from failure. The auto tune has set max and min settings for the H&L settings and as long as the engine is sound then it will just reset itself to the required settings if the engine is modified in anyway - that is the experience so far. I have seen 540Ts with impulse lines off and the autotune has kept the saw running albeit with a dodgy idle - importantly though, no piston damage!
  16. Next time it happens, undo the fuel cap, replace it and try starting it with choke no more then 3-4 pulls and then fast idle only. If it still won't go, check the spark!
  17. Sounds like it is possible that the saw is lacking compression but is difficult to measure on these big saws. I still wonder if the top ring has stuck in the groove after the piston stop episode!
  18. Well you tell me - you paid me to do your saws:001_rolleyes:
  19. Take the saw back to the dealer and ask him to start it and you will pay the bill if it fires and runs! Either you have some sort of starting issue or they haven't fixed the issue! The warranty thing - if the issue was caused by the piston stop breaking then it is your fault. If the issue has been there since day one or has some sort of manufacturing fault then it is a warranty issue, difficult to tell at the moment. I would pull the spark plug out, turn the saw upside down and pull the start handle over fast 3-5 times and see how much fuel comes out of the plug hole. Light vapour is fine but if it splatters and drips out then it is flooded. If it is flooded, pull it over hard a few more times, let it dry overnight with the plug out, heat the plug up with a plumbers torch or gas hob and then put it back, use the fast idle and full choke and pull it over hard 3-4 times and then knock the choke off and give yourself a work out - should fire or pop/run. If it doesn't - back to the dealer or find another route to fix it.
  20. Tried the long nose pliers on a 357XP....worked OK:thumbup:
  21. https://en.wikipedia.org/wiki/Winter_of_Discontent https://www.theguardian.com/politics/2016/oct/12/labour-liam-byrne-lowest-point-theres-no-money-note These are the two labour governments that I remember in my adult life, not a great track record TBH. I guess the students like what Labour promise as at that age they have little to lose and as they grow up, earn and have assets and pay taxes, their views may change.
  22. Guess it could be worse, Earth may be hit by a meteor overnight! Tomorrow will tell how much damage has been done!
