she's alive, she's alive.did everything adw said and after pressure testing the carb it was leaking down on the needle after fitting the rebuild kit. lengthened the spring a smidge not sure if that is the thing to do? and was holding tight.oh the little things that makes this fen boy happy,a running from wreck two stroke chainsaw.thanks to all that commented and helped me get this back up and running especially adw you are a top man.like i said before this is a little tinkering pastime and learning all the time.now for the next one.

i think this saw has been apart before because a few bits missing on strip down,i have a scary feeling the piston is on the wrong way round.when i took the cylinder off to get the boot back on.i was going to check this but forgot[bad memory].should the gap in the piston face the exhaust port or carb.

ok so i think its as it should be . i will take it apart tomorrow to double.umm not looking good. why would it not run with fuel down the plug hole that is a bit worrying.

ok so all back together and a non runner even with fuel down the plug hole.so my few questions are it has a tillotson carb with two inlets one for fuel and one for impulse which pipes go to which one,the one on the top or the one on the side.and the metering arm where should it be set height wise i have it level with lowest part of the carb or should it be where the gasket sits,so they are my two things to try apart from that i'm at a loss thanks all

ok thanks so i'll just order a kit for the hs series

ok so she is going back together and i am going to order new carb kit but my carb numbers dont match with anything on the net.carb says on it S237A804 TILLOTSON,

ok thanks thats good to know,is there a knack to the crank seals,lube up well ? do i remember someone saying about a making a thin plastic tube to slide over the crank

ok so stripped the 625 down a bit more and the boot clamp is the wire one as ive seen other videos with the same sprung wire one its not a great idea though.also one side crank seal is blowing so going to replace them both.now the carb boot should have a strengthener ring inside it which isn't there and no one on the planet has one can i replace the carb without this or is it a must have or will something else fit.thats all i can think of at the minute thanks all

to pricey for me lol

ok i'm gonna ponder on this one cause if i knacker this boot up i will guess its gonna be just as rare as hens teeth to replace.

i cannot find that part for love nor money or anything similar it has a bit of very hard shaped sprung wire at the moment.i haven't got round yet to crankcase seals but will prop do them as a matter of course.

ok great i have spark cant fire it up as its in bits for full clean and degunk.i am still worried about how to get this intake boot on and the air leak i have around the cylinder lip where the boot goes on as the wire clip is not holding well enough.the picture on internet shows a plastic cliip with a screw which looks better.i dont want to buy any parts yet because if i [we] lol cant find a solution to that then i think the rebuild is pointless as i will have a permanent air leak from the off.

hi how do i do that. can i do it in situ with a multimeter. i do have a spark but it could still be the coil?

hi all i have just bought a 625 in a job lot bundle with other things.compression is good 150 but i have a small leak in the intake boot its just not sealing up. i eased it off to have a look and all is ok now i can't get the blimming thing back on.it looks like the only way is to lift the barrel up and is there a better way to seal the boot other than the wire clip.i haven't got it started yet but everything is there to start but it just won't even with fuel straight down the plug, thanks vince

since iv'e rebuilt it and got it running order i havent had chance to run it in anger for very long. it may have to wait till later in the year till i can take it to work when we do or tree work.
