the pilot jet on the pred is it ajustible or do you have to do like the mn. jet and replace it with a diffrent size. i know in rocky mnt. the make a pilot tool so thats why i was wondering. and if it is ajustible how many turns dose it take do up the jet a couple of sizes? thanks in advance for any info.

 

There is a pilot screw, but you have to drill the cap out to get to it. I personally haven't messed with it. I put a 50 pilot in and just rock and rolled. Thats what I'd probably recommend for you as well.

 

The pilot jet works with the mixture screw, they are in the same circuit. The jet is a fixed size hole, in a piece of brass. Its replaceable, bigger and smaller, for large changes. The mixture screw makes small changes, and is adjustable, for changes in temp, and humidity, and day to day changes in gas. You would change the pilot jet, only if the range of adjustment, in the mixture screw isnt enough.

carb
#40 is the plug that needs to come out, and 41 is the mixture screw, its on the bottom of the intake tube of carb,just in front of the float bowl

 

thanks for the info . but all i can see that could be a plug is a brass piece is that it and if so how do i get it out. thanks

 

Thats probably it, sometimes they are plastic.
Find a small drill bit, and I usually use a pin vise, which is just a screwdriver looking thing, with a 3 jaw chuck , that grips small diameter drills and pins. It wont take much effort, because the brass is thin. Just drill far enough to get thru, if you go too far, youll hit the mixture screw. Once you have a hole, in the brass, get a sheet metal screw, or wood screw, and screw it into the small hole, and once it gets a good bite on it, use a pair of pliers, gripping on the screw, and wrench it out of there. Dont worry about wrecking the brass piece, it gets thown away, once its out.
