Title: Rolling road & carb set up recommendations Post by: motoloco on 05 January, 2020, 07:01:11 PM Hi
My S1 1.3 S runs very well, ticks over evenly and, apart from a slight hesitation when accelerating from part-throttle, pulls well. But it runs rich, with a strong exhaust smell and the back panel quickly gets sooty (it’s a white car). It has an Omicron Gp4 exhaust and also a pair of their fast road cams, but standard Solex carburettors. Can anyone recommend someone with Fulvia/Solex experience who can set the car up properly? I’m near Silverstone Circuit and someone local-ish, if possible, would be great. Thanks Nick Title: Re: Rolling road & carb set up recommendations Post by: lancialulu on 05 January, 2020, 08:10:17 PM Cant recommend anyone but sounds overfuelling. Float valve, fuel pressure and float level all culprits. I suspect this is running over rich at lowish revs which will not be a problem driven hard and long.

Nr Launton, Bicester, to cure a driveability problem on a Formula Junior Race car. He did a good job for us, worth a call. Tel. 01869 278942. We are based near Silverstone, so it wasn`t too far to go. Also Northampton Motorsport, on Rothersthorpe Trading Estate. Tel. 01604 766624.
Good Luck Title: Re: Rolling road & carb set up recommendations Post by: motoloco on 05 January, 2020, 08:48:52 PM Thanks both

A quick look on google maps shows they're about an hour away from Silverstone so not as close as Jaydub's suggestions but I thought them worthy of mention. Title: Re: Rolling road & carb set up recommendations Post by: motoloco on 06 January, 2020, 02:24:35 PM Thanks Scott
