Mantis Tiller modification

A few years ago, based on the recommendations from my Bro’ at Groundscaper, I purchased a Mantis Tiller, it’s brilliant, but I have just one complaint which I think is a design fault, the plastic throttle body, which is built into the carburetor body, keeps snapping off, as this is a weak spot.

The petrol 4-stroke Mantis Tiller uses a Honda GX25 engine, which is common to many petrol operated garden tools. The problem is that Honda do not supply the plastic throttle body as separate part, and you need to purchase a new GX25 carburetor body, price from Mantis UK - £95!

The support man from Mantis, did state, they could be purchased on eBay for £10!

This is the replacement part I purchased from Hong Kong - here, if you look closely at eBay, there are some available with a metal frame here

Originally, I was just going to transfer the plastic frame from the new part to the old part, but it did not fit, so a complete carburetor body swap was required, but before fixing back onto the engine, I made the following mod, to strengthen the plastic throttle attachment (Thanks Mike B. for the suggestion!)
