Sounds like a fuel restriction. I would seriously check the fuel line as if this has gone, you may damage the saw if run. The fuel filter could be blocked but less likely. Other than that - check the carb over - could be sawdust in the carb gauze filter. The tank breather may be blocked so worth a clean!

I thought the new carb had resolved your issues:confused1: Guess not:thumbdown:
-
Not sure if the L jet Eddie speaks of are the 2-3 holes in the base of the carb that let the fuel in to the bore of the carb or the jet in the metering section but how about opening up the small semi circle in the throttle valve so you get a greater blast through of air - it may give a result that then other actions can be done to make it work better. In manufacturing I sometimes made big adjustments to machines to see what result it would have so it could then be reset to the datum and a smaller adjustment then made. In this instance, if making this semi circle larger makes it worse then rotate the valve through 180deg and make it smaller! Sometimes they already have a smaller cut out on the other side!
-
Yes, circa 7-10psi
-
The metering lever needs to be level with the carb body or 0.3mm below. You had better check the needle valve is sealing 100%. The wear would probably happen on the soft carb body rather than tbe adjustment needle screws.

Never had that happen:blushing: the missing hairs on my arm were a skin conditon.......until they grew back:lol:

between the clutch drum and the crankshaft - you need to remove the clutch and clutch drum to get to it!
-
Good point, we were thinking it was the non autotune unit
-
The same part is listed for the 372 Xtorq - this has the same bottom end as the 372XP so you should be OK - 510 11 57-01 is the boy:thumbup: The earlier ones will have a different number and the limited coils will have a more aggressive advance curve!
-
Yes, they appear to be:lol: It worked for my wife and her bookkeeping service. My brother used the local paper and that worked for him to the point word of mouth took over!
-
Need a comparison using the same bar, standard machine if possible! Forgot to tell you Matty - your piston ring and circlips arrived for the attention of Miss Fxxxxx I know you wear your hair long but is there something you are not telling me......did that Monty Python Lumberjack song have a lasting effect:001_tt2: Just kidding:lol:
-
Not a bad call on the main metering diaphragm, the pump one jsut stops the saw running but does let it fire every now and then - almost killed myself in the earlydays on an old Jonnie that had this:blushing:
-
Oh. And welcome to the forum:thumbup:
-
Is the choke opening up fully when the choke is taken off? Is the metering arm at the right height? Could be wear in the H screw seat!
-
That doesn't look too shabby - get the dust off and give it a little tune......or two:sneaky2:
-
Greensripe or give FR Jones a bell!
-
Just done yet another MS200, pulls 190psi and feels like it should be good - not bad considering what condition it came in!
-
I haven't personally done a 550 to date, this 560 I have done has had a life and the top end was hanging on a wire until I worked a little magic. It has had A LOT done to it and if the auto tune handles it then I think others will follow suite. The machining gets done at the weekend and the rebuild a week later - just too busy to get it done earlier. Cost - PM me for a few costs if you are interested.
-
Yeah Joe, take the lid off yours and look inside, I think you will find the ports have been opened up a tad:sneaky2: I think the Christmas fairy could climb through the exhaust port:thumbup:
-
Couple of ideas, it is possible the starter cord knot is sticking well proud of the pulley and catching the flywheel or pawls. Make sure the not is always small with no excess sticking out....it can catch and THEN you will know it. Check the flywheel starter pawls are free moving and have a nice bit of spring to them so they return sharply. Make sure the pawls are not bent. Check the pulley is in good shape with no excessive play in the central boss and the central gear has no deformation on its edges where it catches the pawls.
-
Same idea, all works and helps with fiddly saws with limited access to the plug hole!
-
I shipped a saw to Sweden with no issues. It has to be drained and boxed well but any country can ship to another in the EU without any customs declarations or paperwork - think I used IPOSTPARCELS or DHL - also sent out to France twice!
-
I now have the block, handle and an array of parts that may...or may not make a saw - thats life with Matty:sneaky2: It is OK, he is a decent guy and I am only taking the piss.....a little. I will be interested to see if the saw does what it should once done:thumbup:
-
If you are driving down the A1m/A505 toward London....... Or I believe there are little men in big white vans that deliver stuff.......mostly Polish from experience:lol:
-
Check the plastic inlet manifold is the right way round, it has an impulse hole in it and must allign with the cylinder and carb properly - it isnt symetrical although it rits both ways round. Other than that, unscrew the H screw and get some carb cleaner down the hole and then try it again. It sounds like high speed fuel starvation. worth checking the fuel line and filter as well as the fuel tank breather.
