Mitox strimmer problems...

Recommended Posts

Got to admit this has me a bit baffled.....

Picked up a Mitox 3600UX strimmer/brushcutter cheap.

looks little used but 'won't run properly'

To date I have;

Changed to fresh fuel, 50:1

Checked fuel line ok.

Checked fuel filter ok

Stripped carb and cleaned with carb cleaner, diaphragms look fine.

Cleaned plug.

Reassembled and fired up it does run but will not pick up revs when given throttle.

Here's the strange bit.....when the on/off switch is moved to 'off' it will pickup revs,  run normally for a few seconds then stop? Is it electrical I wonder?

A new carb is £50 but I have a sneaking suspicion that it's not the problem.

Any thoughts from the P.W. posse?

Thanks.

Mitox run on 40:1. Mine did anyhow. 

Also sounds like carbs 

Also just thought about it, mine was a cow to run tidy, if I remember I had to leave it idle for a few mins to warm up, I also adjusted the carb as it would just blurb out. It ran really well after, I was quite impressed, a £15 jobbie of ebay which I tfr and pressure washed and made £60 profit. Wish I didnt sell it, just all my gear runs at 50:1

Air leak between the carb and manifold could be a possibility.

Does it run better with the choke on,even when warmed up?

this is the reason why i dumped all my strimmers chainsaws air blowers..............cause i got sick and bloody tired of messing about with them to get them to run right and start properly

 

everything i have now including pressure washer is all sthil...........................total no brainer

even get a 2nd hand sthil rather than a new rubbishy thing.........

 

reading threads like this make my skin crawl....remembering the years of lost time and waste of breath and angst stupid machines have caused me......

It may be just a simple tweak to the carb, I had a new Titon and it does say in the manual that after a couple of hours running to the adjust the carb. My mate did it for me after an hour or so run time,and it ran fine. I got a set of pacman carburetter screwdriver's for a tenner so I can do it myself. It just requires the tinyist movement and its runs just fine.

I have a mitox multi tool and that too was temperamental. I took it into the local mower man and mitox dealer and he serviced and tweaked the carb which he said can need adjustment time to time. Mix is 40:1 and he also recommended use of Briggs and Stratton fuel fit. Now starts runs and Revs fine.
 

Thinking of picking up one of their chainsaws as well as come with five year warranty.

It's certainly a weird one. Normally when the ignition coil goes it will start and run fine for a few minutes till it warms up then stop dead and won't restart till it cools.

Just a thought, seeing as the cutout switch just earth's the coil to stop the spark I would check that the coil retaining screw's are tight and if there is an earth cable to the coil that it's connected.

Thanks Born free, will check coil screws and electrics in handle too.

Dave; Mitox have a fair rep for saws amongst the arborists I believe.

I had the same kind of problems with mine, after a bit of investigation I found the fuel supply pipe perished & split, the split was hidden in the rubber grommet where the supply & return fuel pipes enter the fuel tank - worth a look 😉

Probably not your problem here but the other thing worth checking is that the gause in the exhaust isn't blocked.

I've found that if you are an occasional user of small engines that using aspen fuel is well worth it. Its expensive but avoids many of the common issues with carbs, fuel lines and exaust. Probably cheaper when compared with how many people throw out perfectly good equipment in frustration.
