Hi From Somerset

Hi have just bought a +2S/130 from a friend - long story but the car needs a bit of cosmetic TLC and some other improvements. She was MOT'd last week and the only comment was of pitting on the rear discs.

Plans are to refurb her over the next few years whilst keeping her on the road and enjoying her. First journey was from the North East down to Somerset so have got to know her a bit. Was surprised that at an average (when not stationary) on the M6 and M5 of about 60mph she returned about 45mpg on a 245 mile trip.

Currently sat in garage with the petrol tank out trying to eliminate a petrol smell when stood in the garage. It appears to be the tank filler elbow. Is this all it is likely to be as the tank appears to be in good nick and there was no evidence of leakage anywhere. Since taking the tank out and storing it in the shed the garage no longer reeks of petrol - is this likely to have been the only cause???

Congrats on the new car.

+2 are know to be smelly, you might have noticed the breather setup when removing the tank. 2 * 1/2" diameter tubes that run over the roof and exit under the car in front of the wheels. So you have 2 large diameter breather that are open to the air, you've noticed the result of this.

The large diameter breathers are needed due to filler entering the tank mid way up. The common "fix" is to modify the filler neck with a barb and route the large diameter breather back to it and use small breather to vent to air. Some people also add a special vent breather valve.

You probably find quite a lot of info on the forum about what people have done to improve the situation.

A week Saturday the 25th is probably the best Lotus show of the year at Castle Combe less than 70 miles for you.

Hi Steve and welcome to the "Plus 2 Experience"!

As said there are lots of things you can do to improve the breather arrangement. On my S130/5 all I've done so far is to fit the MX5 non return filler valve to prevent fuel sloshing out of the filler cap on right hand bends. It didn't work well but that is more to do with how I fitted it (badly).

I'm rather surprised at your fuel economy. Which engine is it? I'm getting what I assume is 20mpg at the moment, though I have read that a lot of this is down to evaporation between runs.

Nice colour combo, is the roof gold flake?


PS, lube those trunnions!

Hi Steve, welcome to the forum.

As noted above, the petrol smell is a well known issue and has lots of previous posts.

Club Lotus put out Modification details many years ago and I have attached the details below.
