Two questions

Ok so two questions here

NGK iridium plugs, i read it before on here but can't find it, what exactly do i need? i got hte NGK part but as far as the other stuff like the gap is what i have no idea bout.

Starter rebuild, I've tried finding information on this and only found stuff about people saying "well i did it" Where exactly is the starter? Im having a hot start issue where i hit the start button after shutting her down and nothing, not even so much as a click, first i thought it was my ignition switch so i bought a new one, even though it didn't fix the problem, the old lock cyl was about to crap out(it did after i took it out and started playing with it).

From reading my options to fix this problem are
-clean ignition switch(completely replaced problem still ensues)
-new plugs(going to do next soon as i find out the exact plugs i need)
-starter rebuild(have a kit on ebay in my favorites just have no idea where the starter is located at or even how to rebuild it since i can't find a wright up, sure i'll be able to figure it out if i can figure out where its located)
-new starter solenoid
-starter relay in the JB

After reading and talking with my dad im almost certain its the brushes going bad in the starter hence why im planning on doing the rebuild, BUT i figure i would go with the cheapest and easiest solution first which would be the plugs.

Plugs= DPR7EIX-9 the gap is set from the factory just drop them in.

Starter= front of the engine by the oil filter. Drain your oil before you try to take it off. Check this link. http://m.youtube.com/watch?v=9EHQJDhxZc0

if there is NO sound when you try to start it, look before the starter (electrically).

even if starter is shot to hell, you will still hear the solenoid clicking (its under right side cover).

I had intermittent issue like your hot start issue at one time, where it would not make an sound when trying to start. I determined that the relay inside the junction box was intermittent. that relay turns the power to the solenoid's coil on or off. basic operation is power to the start button (provided by ign switch, run/stop, and the various safety switches in the circuit) to activate the relay in the junction box. that relay supplies power to the coil of the solenoid, which in turn supplies power from the battery to the starter

I solved mine by bypassing the relay with a jumper wire (NOTE: you will by pass the safety switches doing the mod)

About the gap, just got the plugs at auto zone and they said that i should check the gap on the plugs just to be safe so what should the gap be? checked the new ones and they are all .032 guess im good ot go since i found a thread that said .032-.036 is what you want.

@New rider

If the starter turns the engine aver at all it's not the starter. The starter JUST rotates the engine. Nothing to do with ignition. So don't bother rebuilding that.

Well i put the new plugs in, and completely cold couldn't get it to start, not sure if i dont have em tightened down enough for if the problem has stepped itself up a notch, but with how it currently is and with my hot start problem im able to get it to start by throwing it in gear and rocking it, i figure it would be a good idea to get the junction box repaired, either i'll get the relays and do it myself or send it off the newrider, and its 20 years old might as well rebuild the starter. If all else fails and i still have the problem with new starter brushes and a rebuilt JB what should my next step be?

Throwing it in gear and rocking and hitting the starter?
