Garden Multitool Review after 2 Years use - PART 6

5in1, GARDEN BRUSH CUTTER, MULTI-TOOL, 52cc Chinese. Review after years (of home use), problems, failures, repairs and also general reliability and complete review, sequential YouTube parts, For an INDEX see below.
These Chinese manufactured brush cutters are sold all over the web and retail shops under various brands, the colors can be like this one (Red), or Blue, Black, Green, Orange etc.etc., and are sold as 4in1, 5in1, and now 6in1 garden multi tools.
This one has the large 52cc motor and is unbranded - but they also come in various smaller motor capacity versions. The cheap (usually unbranded) ones like this one are all very similar.

In 2015 this 5in1 cost £109.99 delivered in the UK. They cost usually a little more now (and sometimes a lot more, so buy carefully!).
Well known Branded tools that do the same job cost multiple times more...
Date of my original posts 2017. (About 15 mins. each part).
2020 - Added to this description (now 5 years after purchase) we are up to more PARTS so an easy find index added below:
Apologies for the rather poor audio in some parts but YouTube don't allow any fix after uploading.
I do not monetize so any ads are Google/YouTube.

PART 1.(2017/18). General description of MAIN POWER UNIT and initial problems on purchase. Reflections on quality. KICKBACK.
PART 2.(2017/18) Continued (kickback) problem on purchase, FUEL TANK repair.
PART 3.(2017/18) Continued, and the ACCESSORIES examined after some use and discussed. Note after post: Reverse winding the strimmer reels did NOT fix the bump renew problem discussed.
PART 4.(2019) CARBURETTOR repair and fix, FUEL PIPES etc.
Note after posting: I did use the tight bung in the end, it was VERY tight to fit but less prone to fuel leaking - so worth the fight to install!
