Not being funny but on the 181, if it is in good fettle, it will need that big handle, the 181 has a very small starter pulley and can be a pig to pull over!
-
Split fuel line, possibly the breather is blocked, if the fuel cap is left a little loose, does it still stop? Check the coil to flywheel gap, a too large gap will fail when hot! Check the continuity of the HT line with a multi meter.
-
You could re-etch the settings on the air box.....it is a common mistake and have fixed a number of saws like this where the owners have got it wrong! The vast majority of saws have 1+1 carb settings.
-
Sounds like the conversation I was having with my boss this afternoon - he is a socialist and was complaining about business owners getting too many breaks! He is also pretty wealthy!
-
I have done an 880 that blew on those air box settings:thumbdown: These settings are standard with limit caps fitted. If the caps are on, they are correct, trouble is, if they are missing, the setting should be 1 turn out on both, a tad more if you are milling with the saw, just to keep the heat down! If you had run the saw in the cut like that, the thing would have seized pretty quickly in any large prolonged cut!!!
-
I thought you had added it TBH, thought it pretty radical and had only come across extra ports added to the back of the cylinder to aid the direction of the scavenging transfer of fuel air mix - closed when factory or open like on your 044 and other saws! Not seen triple transfers like this before but not done many Dolmars! Extra ports bored in to the cylinder wall are a bit radical on long term work saws IMO - bit heavy on the rings!
-
I'm surprised that there was enough wall thickness to get it in - you wouldn't want to drill through that:blushing: Interesting though, I guess the triple transfer just allows a change of scavenging & less fuel stacking but thought it may risk the exhaust gases being blown backward rather then upwards and down out of the port as normal. I know The MS200 benefits from more torque over the 020 from having split transfers - interesting stuff, guess it was a drill down through the cylinder and then breaking out in to the cylinder with a burr!
-
I take it is a MS261? Autotune?
-
Looking, I think it is an auxiliary transfer??
-
Wes, is that a finger port but on the exhaust side, a bit weird, seen staged and auxiliary exhaust ports before but this looks different, you got an image of the exhaust side or is it misleading?
-
If the choke on an engine doesn't fully seal, the engine will run on choke. If touching the throttle knocks the choke off then if you get to the throttle fast enough, it will continue to run. An engine is very unlikely to continue to run on full choke - that is with the choke valve fully sealing the carb bore.

I think the other bush fits inside the oiler worm drive! If you have fited a new one, it may have a phosphor bronze bush already fitted - not sure though, check the fit!
-
Those two tests have saved me hours of work on many saws and have saved many saws from early demise by finding many seals on the edge of a bad leak. Goodluck
-
At 5 litres for around £2 from family bargains, is it really worth it??
-
Make sure the crank seals havent deformed around thier sealing rim against the crank - easy to do when fitting - need to wiggle a little over the ridges! Other than that - impulse line, split inlet manifold, L screw running lean or the throttle rod is being held open somehow - perhaps catching on the petrol line! Also check both internal sleeve and outer sleeve are on the manifold where it seals against the carb. DO NOT RUN at speed as it is - if alll else fails, get it pressure and vac checked - also check the decomp valve is closing OK!
-
I recently ported a 268XP and although a different saw, it had plenty of go to it when done and resolved an annoying habit off revving on after the throttle was closed! I didnt hear what the owner thought but that is often the case. With old saws it is worth checking the compression is good and the top end is in good shape as a first pass!

Jon prefers butts to hooters though:lol:

The results of the poll are a bit interesting, Labour seem further down than I would expect and am glad that perhaps how they left power a few years back has stuck in some minds. The UKIP vote is a bit worrying, they have some interesting policies but am personally concerned by them being a one man band and if they got to power - what about all the other services that they haven't spoken about as much as immigration! That BBC poll is a bit interesting, seems I am a Chainsaw God:thumbup:

Had tennis elbow after trying to start a reluctant McCulloch strimmer at a strang angle, took months to get rid of and was very painful. There are some aids that are like rubber bands that you use to strengthen the extension or splaying of your fingers rather than the typical gripping motion that are supposed to help. Mine took months to gp:thumbdown:
-
Then what about Vermouth and Vermooooth, and what is wrong with a car boot or good old rubbish? I get a bit peeved with us English following some of this US crap - when did we start having Malls - what was wrong with the Arndale and Whitgift centres? Anyway - who is up for testing a K&N filter and reporting back?
-
This method makes a lot of sense, the only time I would say it may be a little out is if the saw has run completely out of fuel and left for 24hrs or been dry stored for a while but in day to day running - perfect solution!
-
Just don't use the decomp valve, that just lowers the saws compression more on a saw that has low compression by design!
-
Once you have used one, you won't turn back.....speaks a man with a ported blower, hedge trimmer and blower.......and all my saws:001_rolleyes: Thanks Andy, always a pleasure - wish more kept their saws as well as yours!
