Blimey, polling is a bit more exciting where you are. What was that about then?

Group hug:thumbup:

And left handed!

Ah, the redneck fix:thumbup:

That will knock it out of balance and may take out your main bearing on the flywheel side in time:thumbdown:

Did a 395 today, big spring, used a 1/2"chisel as a lever and it worked pretty well!
-
It is usually a case of leaving the brake in the on position - this allows the spring to be less compressed. You can then thread one end of the spring on to the plastic bit on one end and then you need to use a big screwdriver or blunt chisel etc to lever the other end in to its channel - never an easy job but it will go back in!

Stick a typical business card in front of the coil, turn the flywheel round so the magnets are in front of the coil, loosen the coil so it sticks to the business card, do it back up, remove the business card and check the coil isn't rubbing on the flywheel when you turn it.

If the carb was a brand new factory one, the issues could be: - 1) Choke not engaging correctly. 2) No secondary compression (top of cylinder) 3) No Primary Compression (no vacuum in the bottom end crank cases) 4) Blocked fuel filter 5) Impulse line faulty/blocked 6) Split/Damaged fuel line

It sounds like an issue with the high speed carb circuit of just lack of fuel delivery. There is enough fuel to idle but not enough to allow the saw to rev up. I would think cleaning the holes the H&L screws sit in may well do it as may just turning the H screw 1/4 turn out. Have you checked the gauze strainer is clean? You need to do it by taking it out and inspecting it with an eyeglass as they can get a bit scummed up and easy to miss! Other than that - make sure the fuel line and fuel filter are in good shape.
-
By "cleaning it out"...you have removed the H & L screws, got some carb cleaner down them and then wound them all the way in and back out 1 - 1 1/4 turns?

I use Parcelforce and Ipostparcels and both are very good but the Friday afternoon is an issue with most couriers as they like to knock it on the head at a reasonable time as we all do. I have found Hermes to be about the worst just dumping stuff on the doorstep, takes longer and are a bit informal for my liking. DHL good for international deliveries.

Dual port front or just cut the existing shroud from around the original hole, open it up and let in a new outlet pipe and braze/weld. Don't forget to tach the saw at the end to make sure it doesn't fry the piston.

The motorway down through Croatia is stunning - empty apart from a few mad Germans and you can turn off back on to the coast road and towns by the interlinking roads. There are loads of islands, Hvar is worth a visit on the ferry. Dubrovnik is well worth a visit and there are plenty of campsites if you like that sort of thing. Croatian Motorways

You or I would do that Barrie, I just didn't want the untrained fella to lean out his blower thinking he was a tuning God only to seize it later as he had gone too far. Just erring on the safe side....even my ported blower has a slight four stroke buzz every now and then:thumbup: What is he like:lol:
-
Punctuation looks fine to me:confused1:
-
Not a problem:thumbup:

Fingers crossed that the new 372 is a belter, the first one is a stonking saw, rock solid and great performer, especially with a little modification:sneaky2:
-
Not done one of these but.....it will be noisier, just make sure the carb H screw is adjusted to accommodate the missing CAT. Is it worth anything - you are having a laugh:001_rolleyes: Setting the H screw....rev the unit flat out, unscrew the H screw until the unit sounds like it is slowing down significantly, screw the H screw back in until it sounds clean again and then back out until it is a little slower and has a slight sound of four stroke/rasp/thumping in the note. Run it for a few days, check the plug electrodes are a brown colour - a dark ginger through to coffee colour is OK, white is BAD and graphite grey is an expensive repair:thumbdown: You will of course, get more performance without it:thumbup:

You did say you loved em:sneaky2: [ame] [/ame]

Well used ones can fry the clutch under abuse - worth checking the shoe contact surface to make sure it is square and also the drum.

OK, sounds like the piston stop was through the exhaust port rather than between the crown and squish band. Next question - what were you doing and what were you using? Air chuck or tommy bar - and how much force? It is possible that the top ring has become stuck in the ring groove due to the compression of the top edge of the piston, this may cause the issues you have! It is unlikely the port would be damaged with what you have done. Taking the muffler off may give you an idea if the piston has any damage to the front.
-
Take the head off, stick an appropriate screwdriver in to the hole the drive shaft usually slides in to and try turning the screwdriver. The blades should freely reciprocate with no tight spots. If you cant turn the screwdriver then you have issues somewhere in the gearbox or blades!
-
The piston stop - which type? one of those metal ones or the Stihl Plastic type? It is possible that you have fractured the piston crown and it makes enough compression to start but not enough on a hot start. Had a 262 like that once! I think it needs a look at by a competent tech before getting too down hearted!
