DOES ANYONE KNOW WHAT THE JETTING SHOULD BE ON A PC18 CARB. FOR A STOCK MOTOR?

 

[motoguru]

that 18 is a pain to jet if anyone hasn't bought yet go for the 20 it is usually real close. as for the 18 what will usually fix the problem is a lot of work.

here goes:

first fill in pilot jet with solder then redrill w/ 32 jet drill

find a 72 main jet and install

needle position in middle

air screw 1 turn open--adjust accordingly
