damaged jet head

I was using a shitty screwdriver to get the pilot jet out, and I damaged the brass a bit. It's far from stripped and very functional head-wise for a correctly sized screwdriver, but I'm wondering if the damage will negatively impact performance.

Anyone have some insight?

Thank you

Re: damaged jet head

No, you will be OK this time but make sure you dont loose the slot or you will have to drill it out and thats no fun!

Re: damaged jet head

I would just buy a set of brand new ones from kawasaki, they only charge me 20 bucks a set, that way not only do you not have to worry about the bad slot but you also won't have to sit there fir an hour and clean them, then as a bonus you would know for a fact that they're clean and properly sized and they'll come out again when you wish. I wouldn't even hesitate at brand new ones.

Re: damaged jet head

Thanks

My narrow flathead driver metal was so thin/soft that it bent (it took a hell of a lot of torque to get it out), applying pressure to the edge of the slot and deforming it.

I should've measured it while I was there - it's actually a pretty large size thickness-wise but has to have a very narrow head. Best option may be to grind one down.

What do you guys use?

Re: damaged jet head

I just use a regular old crafstman but I never tighten them down too hard. I watched ducatiman do it nice and easy one time then I remembered to do it like he did it when the time came for me to do it myself. All the jets and all hardware on the carb for that matter nothing needs to be overtightened. Just snug.

And you can't use some ten cent screwdriver either. A good mechanic should have a favorite.

For electrical work all we use is Klein tools. You're not a real electrician unless you have a pair of kleins hanging out of your back pocket. Its an electrician thing. I use a kelin 6006 straight screwdriver. Been using the same model for almost 30 years now. I wear them out one per year. They cost about ten bucks. The old ones I use for chisels.

Re: damaged jet head

Funny, I was using electrician tools for this build too. Unfortunately I didn't have a flathead small enough, so I ended up using a computer screwdriver. Was able to bend the shaft a quarter turn without the pilot jet budging.

I think the previous owner had a phobia of loose fasteners. Red locktite all over the valve adjusters etc.
