well got my engin instaled but now i can't get it started .got it running for about 2 min and than it died and would not start tryed adjusting everything but nothing helps any sugestions?its a cv-rx 12 slide carb .Once you set them back to factory settings start leaning out the hs neddle a 16th of a turn at a time pull about 6 -10 times then another 16 pretty soon it will fire over once it does let it warm up a bit then start fattening it up again. This is what I had to do to mine was lean it out a bit to get it started then fatten it right back out once I got first tank through it she was pretty friendly

Ditto, ditto, ditto - great advice fellas.
Is it cold where u r running? You might try heating it up for a few minutes with a hair dryer b4 starting it up.

Discussion point...NOT a slam or flame!
Wouldn't MORE compression create more heat and actually help the glow plug?

I am glad you brought that up i wasn't gonna go there but since you did. I would have to agree more compression is better this will compressthe fuel more which should make it hotter and cause it to ignite easier I would think.
Think about this you tend to flame out motors when they get to hot becuase they have lost compression due to the fact that the cylinder has expanded to much.
Can you please explain your theory on this matts. X

...makes sense to me X...
I suppose what could be the case is that due to the fact that you'd be running so rich to start out with, that there's just too much fuel and it's fouling the plugs designed goal of heating itself up from compression for the next power stroke.
So if you heat the plug externally via the battery...it's hot enough to continue the 2 stroke process.
Here's a puzzler: How hot do glow plugs get during the two cycle process compared to how hot they get with a battery? We've all seen them glow brightly from a fresh starter, but NO-ONES seen one glow from the actual combustion process.

Is the light on inside the refrigerator when you close the door?

These are diesel engines, the glo-plug only starts them, after that, the compression takes over and continues to fire the A/F mixture.
The glo-plud contines to stay hot but not glowing.

Diesel engines? If they were Diesel, then you'd be buying diesel fuel... It IS a similar process for starting them though.
BUT, I beg to differ - maybe I'm off my rocker...but the combustion cycle heats the glow plug up for the next combustion cycle. The combustion does NOT occur purely from the compression of the fuel/air mixture...but from the heat in the glow plug retained from the previous cycle.
That's why there are different "heat" ratings for glowplugs. A cool plug will not retain as much heat from cycle to cycle as a medium or hot plug.
Don't you love these technical discussions?

Maxx I used to fell the same exact way as you. What you say makes perfect sense. I actually went to school to be a deisel mechanic. Thank goodnes for having to take that computer concpets class.. Anyway your throry sounds great untill you stop and think about a few things
1st why can a fouled plug interact with the way a warm engine runs? causing it to run poorly or eraticly?
Now take it a step farther why do they have diffrent types of plugs hot, cold and so forth? If you are running a hot plug and having issues flaming then why do they tell you to go to a cooler plug?
Lastly think of this.
We need Someone to take a glow plug and heat it with a good igniter and then temp it with gauge I would figure its not more than a 2 or 3 hundred degrees F .... Then think about how a motor will easily hit 300 degress if lean. Thats the exterior. Now think about how hot the inside of that combustion chamber is along with the burning gases in there its one hot mama. I mean a regular car engine is like 1500 f inside the combustion chamber.. the gases when ignited i mean.
So these are the things that when I talked to some very experinced nitro guys that got me to see the inticaies of the glow plug. X

i had an engin that i couldnt start once, it ran for about a min or two but then died and couldnt get it started again. then i realized what the problem was...my fuel was not good anymore. i opened up a new bottle and poured some in and started once the rest of the old fuel was out of it.
