EZ-Just screw: too tight or too loose (how many turns)

Hi.

I've gone the route of a deluxe tuning kit, rebuild kit, and EZ-Just screw. I've read the various thread re screws being too loose.

One question; I cannot work out if mine is too tight or too loose (or both!)

How many turns should it go in before it seats? I only get about 2 or 3 until it feels like it is seating ... or, conversely, I can only turn it 2 or 3 turns 'out' after I think it is seat at which point it falls out ... and I don't want to force it. However, the old OEM one goes something like 9 or 11 (cannot remember and is not with me right now).

My carb had had the plug removed before I got to it. I'm thinking now I am hitting a tight spot. Obviously, I don't want to damage the kit.

*IF* a kit was ever released with a threaded top hat insert or helcoil to suit, I think I'd be first in the queue.

Ditto, if you were to sell the little bronze top hats that the long screw uses to go through the plastic top.

Perhaps a better question to ask would be, "what is the measurement between the carb and the knurled knob of the screw?".

I can turn the OEM screw in 12.5 times but the EZ-Just only about 3.5. I don't want to risk damaging it.

I've measured it up to the outside of the throat, and risked forcing it in a little. The threads on it start to polish as if they are cutting into the alloy a little.

How deep does it go in? Does the needle tip go all the way upto the small hole?

Thanks

I noticed that with mine also. I have yet to test fire it and see how my adjustment is, but I found pretty much the same thing, and that is after chasing threads with an M6x0.75 tap. I may throw some nail polish on threads just to keep it secure as it seems pretty close to falling out.

I'm thinking for the price of a 6mm Helicoil or threaded insert, it might be worth doing the job properly.

I bought the item before reading over this forum and am a bit shocked by the reports of bikes dropping screws mid-journey. This might be worth the manufacturer mentioning it on the sale page.

I think their response is reasonable enough ... it's cast alloy and the tolerances are loose and wide ... but I am glad I was made aware of it before I also started the bike up and rode off.

I've got some catching up to do but will see what measurements I can take myself later. I'm pretty sure I am not bottoming out, and hence damaging the tip, but there is no way I can either manipulate it by finger further in, nor leave it loose out. I would need to use a large screw driver and considerable force.

• Is that what the thread is meant to be ... -0.75?

Thanks.

I took my EZ just mixture screw to a well regarded fastener/contractor supplier here, and he measured it as M6 x0.75. Sold me the tap, I cleaned the threads and installed my EZ just. I will likely remove it, and apply some nail polish to threads before riding to ensure it stays in place.

Thanks for the info with the pic. Now I know where mine should roughly be.
