Ask a specific question

In another thread I was b#tching about the motor sprocket/chain fit.Well I just ordered a new sprocket from Dax.When I was working on the initial sprocket I tried to remove it and it didn't want to slip over the shaft threads.Not wanting to force it or strip threads I just worked on it in place.I noticed the pin or key but that didn't seem to be holding it.Is it suppose to just slip off over the threads or do I need a puller.Thanks,Ron

Thanks Ilikeabikea
I can see Norman is using some sort of puller but I'm still not clear on this.Can I get another hint?Ron
 
You should have gotten one with your kit.

I have a couple extras around here somewhere, I will gladly ship you one for the price of postage....5 bucks I think would do it.
 
Thanks guys
Hey I have one of those.I guess it supposed to be obvious what that little gizmo is meant for.Not to me.I thought is was a part that fell off a Chinese mill on the factory floor.Ron
 
Well due to the hype,I just had to run out and buy a NGK B5SH plug.Any excuse to spend more money on this project,even though it ran great on the original plug.**** $2.00,I can live with that The question is:What gap do you guys put on the NGK.The original was gaped at about .03.I was going to replace the wire but when I looked at it I could see it was copper.Can"t do much better than that can you? Thanks, Ron
 
I use .020-.022" on Norm's advice....seems less is better on these little engines. (my guide said 0.032")

When you use your puller if you have some use a light coating of never seize on its threads or motor oil to help prevent it from galling the threads. Pablo gave you the gap for the plug but I'll add use what works the best even if you have to gap it a little closer. We had an 1100hp industrial engine that used 0.017 plug gap. But the 0.020 to 0.022 works good.

Regardless of what the plug wire is made of, you can do an improvement to your spark with a good 7mm wire and new cap.

Good wire/caps give a better spark than the China co. engine parts.
 
is this tool you all are talking about a thing that looks like a cheap spark plug removing tool? could you post a picture of it. i am afraid i may have thrown it away :-{

One of 'em came with the extra sprocket attatched...the other without. My latest kit didn't come with the tool at all.
 
That's good - and you got a spare sprocket! :D Did the sprocket screw right off?

On a serious note, the supplied puller tool worked fine for me.
 
thanks. nope i didn't get one of them either. dax has one for 7.99 if i get where i need one. i just checked
 
Just make sure when you use it, you oil it up reeeel good.

The threads are fine and look a bit delicate.
