Most engines can be set at one turn out to get them started. Adjustments are then made to get the best results.

Got a flymo maxi twin 430 two stroke, how do I get the idol screws in the correct positions so it will run?

Are you sure it's the idle adjustment screw or the carburetor adjustment screws? If it's the latter you'll need a specialized driver. They no longer have screw with heads a screwdriver will turn

How do you adjust high and low on carburettor

not sure what you mean, idle? High idle usualy bend a rod to position the cam in the right place when engine is cold or with the choke plate held about 1/8" open and low idle is turn the idle screw with the engine warm. The screw rests high on the cam when cold and low on the cam when engine has warmed. you may find an index marking on the cam.

How do I remove the upper shaft of my flymo power trim 300?

It would seem to be one that snaps into place and isn't supposed to be removed.

How to fit new fuel line to a Flymo maxi trim 430

Removing old fuel line/disassembly
  • Empty petrol tank
  • Use a hooked/bent piece of wire or similar to get fuel line and filter out of petrol tank filler hole
  • Remove fuel filter from end of fuel line
  • Remove air filter housing
  • Remove choke control/ plate from carburettor
  • Ease old fuel line from carb. inlet. And clean inlet tube if necessary
  • Gently but firmly pull old fuel line through hole in base of tank
Fitting new fuel line
  • the new fuel line has too big a diameter to fit through the hole in the base of the fuel tank.
  • To get round this I heated the end of the tube with a lit match (but a blow torch or gas ring would do) until it was soft enough to fashion into a point- take great care the plastic obviously gets very hot and could burn ***** flesh. The tapered end you form should be at least 1cm long. Allow to cool
  • Trim off the end of the tapered point if necessary
  • My next problem was to get the tapered end through the tiny hole inside the fuel tank. To help with this I took the innards out of a standard biro then put the fuel line through the empty tube with the tapered end projecting from where the ballpoint used to be. Push the tapered end through the hole inside the tank.(a torch was useful here to help see inside the tank)
  • Pull the fuel line through from below the tank until you have enough to push on to the fuel inlet on the carb.
  • Cut the tapered end off the tube and push onto the fuel inlet .
  • Cut the other end of the tube so there is enough length to reach all parts of the fuel tank.
  • Attach fuel filter and push it into petrol tank
  • Refit choke plate and air filter housing

What is the initial carburettor adjustment for a mac 120 MCCulloch chainsaw?

Hi williamsc32...
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.

My flymo maxi trim 430 fires but won't run and just dies after a few seconds

If you have some starting fluid spray, a little into the carburetor and see if it runs. If it comes up but then dies, there's a fuel supply issue. Check for leaks in the tubing, a plugged fuel filter and be sure your carburetor is securely fastened to the motor. Any leak keeps it for sucking the gas into it. Your gas tank needs to have a vent to let the air in to replace the gas coming out but it usually takes a while for this to kill the engine so it'd be last on my list. Good luck.

No user manual


Most 2 Cycle Engines use a 32:1 or 40:1 Fuel Mix Ratio.
The Newer 2 Cycle Engines use a 40:1 or 50:1 Fuel Ratio.
For Better Performance and to be sure you have Plenty of Oil to the Engines Internal Components, I Suggest (and I Use) a 32:1 Ratio in All my Equipment except for Post Hole Diggers.
Post Hole Diggers Use a 25:1 Fuel Ratio.
Hope this Helps.

Good Luck

I have a poulan 2150 chainsaw and the chain never stops spinning. how do i adjust it to stop spinning when i am not cutting?

Firstly consult your manual regarding carburettor settings. There should be a high and low speed adjustment on the saw, often called or labeled as "L" and "H".

These are often located on the main motor body, closer to the handle on one side and require a screwdriver or similar to adjust. They might be buried and you have to look down the adjustment holes in the outer body to see the screws.

Basically you need to adjust the "L" or low idle screw.

Firstly, warm up the chainsaw and allow it to get up to temperature... The blade, as you say will probably be spinning still with hands off the throttle... Grab your screwdriver and adjust the "L" or low idle screw turning it counter-clockwise (at least on most saws) very slowly until the chain just stops turning on the bar. If you go to far you may stall the motor. You just want the chain to have just stopped moving on the bar, and that is your "L" setting position...

Has to be done with a warm engine though.
