After the St.Roses car show I thought it was time to have a look at the rubber carburettor mountings. These are common to most TR7's and are a well known problem area. The original production items were good quality rubber and lasted for ages but modern replacement parts seem to use inferior rubber and fail quite quickly. This can cause air leaks and poor running so needs fixing.

(There is a similar problem with engine and gearbox mountings where the modern replacements are much too hard and cause noise transmission into the car. I was lucky enough to be able to re-use some old stock original ones which are much nicer.)
The Triumph Dolomite Club sells some very nicely made solid aluminium mountings to replace the rubber ones and I bought a set of these together with some more replacement spark plug tubes as mentioned in a previous post.

Fitting them was not difficult but I have upset the carb balance so need to re-tune the engine !

Next job on the list was to sort out an annoying clonk from the exhaust. Its a very nice fully stainless system that I got from S & S Preparations and it was touching somewhere at the rear of the car but not all of the time. All the mountings were OK so I checked all the clamps and went out on a test drive - nothing at first then lots of clonks after a few miles. Looking again I realised that when the system gets hot it was hitting the towing eye on the rear chassis rail. This was soon sorted out with the angle grinder and it now has plenty of clearance !
