Re: How to \"jet\" an engine
NEVER UNDER ANY CIRCUMSTANCES "DRILL" A CARB JET!!
An immense amount of time, millions of dollars and countless thousands of hours of effort go into getting the passages correct, and it only takes one chimp with a drill bit to screw that up...
If you need bigger jets, buy correctly made larger flowing jets, don't just take a drill to them...
When you 'Drill' (mangle) that jet, you can actually increase the size of the passage in the jet, but DECREASE the amount of fuel that will pass through it. I've seen it over and over again.
(Let's see if the 'Drill' guy can figure that one out... Anyone that 'Drills' jets won't be able to...)
First, we need some info on your carb and engine.
Operating vacuum, idle vacuum, what RPM you normally run, what your top RPM is, How many miles the engine has on it, ect.
Then, you will have to buy a vacuum gauge, and some new spark plugs.
Get back here when you have those items and we'll take you through it.
Ask for 'Carb Rejetting Help' and I'll keep an eye out for the post.
This is actually much easier to do correctly than it is to screw up, but most of them do it the hard way anyway...
So many cats, so few recipes...
