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 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!)
