Hello,
I've got a Pinasco 225, Meceur 60 mm cranck, adjusted, SI Carb 26, ignition timing on 18/19° and Taffspeed MKIV.
Carb settings are : 160-BE-125 and 155/60 slow runing jet, 2 holes in the air filter. So one month ago, runing at 110 km/h the engine locked tight !…
So I buy an other Pinasco 225 (model 225 with the head), I try differents main jet : 135, 132 and 130. The 130 is too big and the engine does not take turns… like a 4 stoke !… I'm not going to put a 128 or 125 ?… So I don't understand ?… Perhaps Taffspeed is not a good exhaust with Pinasco 225 !
Before I was running with the SIP Road, but impossible to go over 110 km/h…
