No, I'm not well up on the curvy and guessed it might have some control over the ignition timing.

I suspected it as my son's new (1999) SV would cough and fart a bit while accelerating & I found that a previous owner had disconnected the TPS. Plugging it back in again make no difference & checking the thing against the values in the Haynes manuals showed pin pair "A" had gone open circuit. Assumed the TPS was at fault.

Anyhoo, cleaned the carbs (loads of rust flakes in there and in the fuel tap which is missing it's filter) and installed new choke plungers and o rings. But I managed to over tighten the drain screws & crack the float bowls! I'm not particularly ham-fisted & that's the first time I've managed that.

Once I replace the float bowls the quest will continue!
