Glow plug problems
 

i run the boat out in the lake ,bring it in for one reason or nother or adjustment,i i stop the engine with controller , n every time i go to restart it .... nothing , so i take plug out touch it to igniter wont glow..... if i touch coil will start to glow, i went through 7 plugs today n alot more in days past..am starting to think a drug habit be cheaper... the boat is a sw32, new 32 dyn , just started 2nd gallon of dynamite sport fuel 30% n 18% oil i believe it to be , both hi an low screws are set on rich side , it is muddyto rev, n getting smoke from exhaust,i couldnt find any leaks in exhaust coupler or preasure nipple ,( was thinking it was sucking in cool air at shut down n shockin glow plug, kinda like burnin a valve ) the coil on the plugs looks shinny n not distorted, i'm useing kb-hp long reach plugs n os a3 , the shims been removed from under button, only copper remains.....an the temp at lake today was 45deg if that factors into it ........i'm in need of some educating.....

I've run K&B plugs and have had nothing but trouble with them. Other swear by them, I swear at them! The glow ignitor that you're using may be pushing too many amps through the coil, frying it.
I've got a power panel ignitor with the amp dial on it and have to turn it way down when trying the K&B's.

MC 9 plugs isthe only way if your into high RPMS

RE: Glow plug problems
 

I run the dynamite .32 also and I use the mc-9, I cant remember the last time I burnt a plug up (knock on wood). Well good luck and good boating. :)

i did do a break in on few of the plugs, heat up for 10 seconds, cooll down n repete it few times ....useing a dynamite igniter, it does light them bright n i charge igniter once a week, i have the c battery igniter but i get 6-7 lights, duracell/energizer n radio shack alk. n battery junk after that point,i might have to look into a power panel setup, not sure am looking to hump more weight ,gotta do sumptin..... will get a few mc 9 plugs tomorrow n burn up half a gallon fuel.do they make a small amp adjustable igniter ?

is that a usa 1 truck in the backgound?:eek:

RE: Glow plug problems
 

yup , you know your trucks.........indistructable truck, lol got kyosho 4x4 baja dodge, durtrax thunder quake, 2 kyosho spiders ,n a off china mugen lookin car,kyosho jet stream nitro boat n..sw36, i set up the thunder quake to pull the sw36 boat n trailer kinda cool w/reverse

RE: Glow plug problems
 

did you ever get the water cooled head to work??

RE: Glow plug problems
 

on the wasp.... yes i did, a k & b bolted right onjust used wasp button under water chamber top, but had a knarly time getting it to fully perform, so i broke down n bought oem replacement for sw36 n a k n b 40 w/frnt rotor n coolin head.thinkin i might drop the k n b into the jet stream, get that os 12/15 outta there

RE: Glow plug problems
 

i need to get this project done:D

RE: Glow plug problems
 

why are you taking that 15 out?? i have a nitro hammer that i have got to go 45mph

RE: Glow plug problems
 

Yes you do! I don't know what looks better, the three speed, the 4 strokers or the MT.:)

littlepiston, when you use the mcoy glow plugs, do you use the copper ring??

when i do, the engines vibration keeps on loosening the plug, i took out the ring and problem solved....i even put it back on for good measure and it came loose......

RE: Glow plug problems
 

I only use McCoy plugs and always use the ring. It never breaks loose. Long life span as well.

Ryan

RE: Glow plug problems
 

well i have been running this one it has a os 40 four stroke

RE: Glow plug problems
 

dirty!!! i need to clean it :)

RE: Glow plug problems
 

when you screw it down make sure you crush the washer when new there cone shape

RE: Glow plug problems
 

does the ring really matter??? the one that it came with didnt have a ring and it lasted a while...

RE: Glow plug problems
 

its a seal it will leak compression and also a spacer , your plug might be to far in your cumbustion chamber and it could reduce power :D

RE: Glow plug problems
 

looks like you have as many projects going as i do, very nice ride you got there ..........the os 12/15 is getting tired , loses compression when it warms up, it's seen alot of run time

RE: Glow plug problems
 

Wow, amazing!!!!! How did you find parts to fit an O.S 40? (clutch, flywheel, looks like it is pull start) Also any video?

Yes, as mentioned it is like a gasket for the glow plug. If your plug ends up being too long because of the lost spacer, your piston may smash in to the glow plug causing damage.

RE: Glow plug problems
 

that'd have to be a pretty long plug or a very small chamber on the head inorder for the piston to hit the plug [:-]



I guess im just another one of the few people who has had problems with McCoy plugs. All i use now are O'donnell plugs and havent had a problem yet.

RE: Glow plug problems
 

There has been a bad batch of McCoy's lately on the market. Watch where the coil is welded at on the tip of the plug as some of the spot welds and/or wire is sticking out by the threads. There have also been issues with insulators leaking or blowing out.
