The Mastiff has been around for many years and while the chassis has remained mainly unchanged there have been changes of engine. If you will post the engine make and type I could possibly have what you need.

quick update
have carried out timing check again and again pretty sure its good. have cleaned carb til it shines 🙂 but still no improvement. plug is new. latest thing i have noticed that after around 2/3 throttle it actually gets worse, which leads me to think fuel shortage. is fuel getting into bowl quick enough? wrong needle? wrong float?or what size should main jet be? as you can see clutching at straws now.
any help or thoughts appreciated or anyone with working carb near derby?

I will try to add some photos, but being a beginner to forums not sure if it will work !
I think they are there. Please let me know if they aren’t

Fibre glass, maybe with some mesh reinforcement, should be ok around the skirt but if there is rot on the top where the blade bearings are mounted I suggest that metal and welding are the order of the day.
Your Mountfield is basically an American Murray so that spreads the net a bit when sourcing parts.
As has been suggested, Garfitts are a possible source of chassis parts – they list a blade G22-031, original Murray part 20083 but you need to be sure about the centre hole. From memory, some were round and were rectangular with rounded ends – known as “double D”.
I’m guessing that it has a Briggs and Stratton engine ? No problem with BS parts. belts should not be an issue but some machines only functioned correctly with Original Equipment belts and were difficult with cheaper ones of nominally the same size from local belt and bearing merchants.
Talking of bearings, I seem to remember that the cutting spindle bearings were OEM specials and difficult or impossible to match with cheaper off the shelf items.

Over for another year. No photos because my phone battery is on the blink. Machinery not always well behaved. 700 Hirth ran faultlessly. 50 developed intermittent fuel problem. Today the mag on the SIMAR 56 plough packed up. More tinkering when I can find the time.
Many thanks to Robert for dragging me off the field with the Trusty and helping push it up the ramps on to the truck!
So I may have to bring the old stalwart 56 tiller to Weeley.

Any company that works on vintage motorcycles will be used to doing such work.

i thought i put the answer it went to a specalist company but they were so tight they thought there was a very good prospect of breaking something so we left alone just in case

after bit more tinkering it looks like the opposite side has also a different cylinder??
so now thinking this good side with the MM cylinder may have been a bodge,and yet was the better side which i stripped down…

as you said charlie I’d have expected the brake parts to be off the shelf cheap as chip’s item’s from back when these were made,but what was around back when these were built?? not alot with 5 stud fitment and even the drum backing plate is an odd one – spend hours looking at images of parts from late 70’s – 80’s to see if i can find a match

After Getting hold of joe turner equipment – they directed me to David turner at greenmech now waiting on a return call …

and after an over night soak if one of the brake cylinders i managed to get a number off it 84946
quick google search directed me to a Morris minor cylinder and they look like a match.

we were going too replace them but 1 trying to get replacements from Mr Hudson was a night mare and 2 the company that tried said they were the most difficult they had ever tried to remove and that is was best just go with what i had for fear of breaking the head in pieces so on balance and the amount of play was not to excessive we left alone

Hi Charlie, thanks for the reply. I am not sure WHAT engine it is as there is no Manufacturer’s name on the metal plate. It just says model 143835 and C1207.25 I have looked on Google and it LOOKS like it MIGHT be a Villiers 12/2 as the old carb the previous owner gave me has got Villiers on it. It started last year when I bought it and I drove it but it was left for a year and won’t start now. I tried and tried pulling it ! I tried Easy Start but no luck. I have put it into my local lawnmower people Handy’s but they say they can’t locate a condenser and points from their suppliers as it is old. I am just about to go over to them now to bring the parts back here to take pics and load up so you can see them. Who is Meetens by the way?

[vhgmcbuddy]

Thanks Trusty I’ll do a bit of searching.

[vhgmcbuddy]

Can’t do that I’m afraid Charlie,The stud face of one of the drums has broken away
