Hi Guys
I've just swapped my 1000cc engine for a 1100cc SPI (187A) engine but left it on on the same carb (32 TLF 5/235).
Information seems to to be scarce but it looks as if the 1100 Uno engine used a 1.05 main jet which is fitted however the plugs look horribly lean with the mixture screw open a turn and a half.
Anybody been here before?
Thanks
