Help with Trackstar Supar .21 Engine
 

Hi Folks, I got my hands on a brand new Trackstar Supar on road engine and want to get it ready for the weekend.
However, I tried to break it in used a medium turbo spark plug from again - trackstar and it doesn't seems to be hot enough to keep the engine running. I used heat gun to heat it up 200F and it will start for a minute than shut down. I even keep my ignitor on the whole time and it will still die. When engine die off, the temp is around 180F, a little lower then before.... After two spark plug and I am ready to quit it for the day.
Any other recommendation to break this in?

Glow Plugs not Spark Plugs. Another thing, You need a fully charged Igniter. Alkaline batteries a fresh batteries, NiMh fully charge or overnite. Medium Glow Plug is enough.

Right, Glow plug... because these don't spark:lol:
I did use a fresh alkaline batteries on the igniter but it doesn't seems to help.
Maybe the TrackStar glow plugs were just sh*t...:confused:
I'll try to get some OS tomorrow and try again.

Any other suggestions???????

What Igniter you using? A cheap double AA Battery? Get a Sub-C Igniter it last longer. I lived in SoCal 25yrs and medium plug is good enough. Those AA batteries your lucky to get 4 starts. Sub-C charge overnite.

I tried AA batteries igniter, D size igniter and I also fabricated a 2x AA batteries igniter.
Nothing work....

What fuel are you using?
You are sure there is no binding in the clutch?
You are sure the engine is not running too rich?

It is possible you got a bad glow plug, although I have had good experiences with Trackstar turbo glow plugs. Try another one just in case. If you tried all those different igniters, it is safe to assume that isn't the problem. The next thing could be your carb settings- maybe it is way too rich?

At 180deg probably running rich, Does it stall when you give it throttle? or just stall right away. Yes could be GP, but use the mid range plug. Check with igniter, a orange to bright yellow is good enough.

Where in SoCal you located? From LA to San Diego medium plug to start ok.

I am in LA area.
Seems like I must be running too rich.
However, I did open up quite a bit on idle needle for it to idle for that less than one minute run time.
I will try lean it out to see what happen.
Thanks!

What your throttle airgap? Should be 1mm. HSN start at 3.5 from close LSN Flush. Turn HSN till it doesn't stall. givig throttle
then turn down the idle.

Where do you run on-road now in LA? Only track there once a month at GLARCRC.

GLARCRC is 2nd and 4th weekend. Show up on this Saturday or Sunday and someone will help you

That's where I will be tomorrow!!!
I was gonna break in the engine for tomorrow but seems like I will need to do it onsite.

By the way, I can't find any place locally that sells a medium turbo glow plug. Anyone can sell me a few tomorrow???

Try Pacific Coast Hobbies on 1747 Pacific Coast Highway in Lomita. Near Artesia Train Station. Or Gizmo's in Burbank off of Buena Vista and Burbank Blvd.. on the web Tower Hobbies, New store in Rancho Cucamonga, delivery one day in CA, UPS/

I called PCH in Lomita and HP in Lawndale, both store don't have turbo plug in medium, just hot for off road.
Hope I will have better luck at the track today.

Where Area of LA are you?
