EB Mods JS Engine
#1788
Then maybe you can elaborate more on why? Look back in emails when this all started Feb. 27th when I was notified I had to send Chris another engine.

From the outside looking in...... I have seen Joe be super helpful to people all over this site, and always seemed to praise EB Mods. From the posts I have seen EBMods seems most concerned about who gave him how many stars in his thread.
If you want to damage your reputation and look like a child in front of a lot of RCT users, keep this discussion going in this thread. Otherwise grow up and don't pawn off your problems on someone that no longer works for you. You are the owner so no matter what you think, the blame is going to come back to you. If you run a business big enough to have employees you need to know how to manage your employees, easy as that.

Please don't make this about something it's not "STARS"... I responded to a question that was asked.
#1791
What I was really trying to get at is..... You are a business man, why are you airing your dirty laundry on an open forum??? If that seems like good business practice to you then you should look into some free online classes to start you in the right direction.

I hope you guys settle your differences about the whole situation. Your were a good team and you played a major part in the 1/8th scale engine brackette in the past 2 years with the JS engine. Its certainly not worth loosing a freindship, so don't let it get that far.

hi ed, ive been searching the thread for info regarding ,shim's for break in,of stock js 21.
ime located in north queensland aus,we run 25% nitro,very high humidity and temperature,its been that wet here the past 6 months theres not much racing
this is my second js21,( with the new crank case ),the first, being my first hi performance race eng,
i had a few dramas with the break-in,ie i didnt pre heat the eng,flooded it etc,but eventually got it right,all the locals are running os p3 plugs,ive changed to p4s and p5s,the pipe came with it vp 3023,recomended by the local supplyer.But i found this pipe ran red hot,(burned presure and fuel lines,and the fuel tank,and body,so i tried others.
no one else has had the problem here.
anyway ive inspected the engine,am about to re-assemble,and run-in,
ime thinking .3mm shim pack,
i ran the first eng in ,in the car,but this time i have a hudy break-in set up available to use ,
any tips?
thanks in advance,ive been scanning this forum for months,and are learning more all the time,good on ya

That's good stuff Noddy2.
I have tried almost all the pipes and glow plugs on that list you made.
My favorites are a OS P4 Plug with a Reckward 2041 pipe.
As far as tuning it is going to vary by fuel, clutch choices, and air density that people are running and the way the weather is on a certain day.

I guess the lack of tuning posts and secret combos is a good thing... Mines always spot on anywhere I go... I left here (4200ft) and raced in lewiston idaho a couple months ago (700ft) and changed my HSN needle maybe 2 hours...and it tempd the same as here 200~ and more power than I could handle in buggy 
Stored it for the winter and been running the last 2 weeks locally, 2 weeks ago after the main it tempd 177 and haulin the mail, beat the previous hero lap track record by .6 seconds so I wasnt pampering it lol

I have been running the 086 pipe and the P4 plug but I am about to strap on the 2041 pipe and try that out. Nothing but good things to say about the 086 but I just want to try somthing different.

If you want to continue to use a .4mm shim, I suggest a P3 plug for a better combustion.

Thank's Michael#81,and JoeGuam.
ime running an OS2060 now,but have nothing to compare,got a Recwards 2041 ord,and will make back to back comparisons,so far,no tuning issues with 2060,
most racers i talk to in north QLD run os p3 in everything,on the coast,ime using p3 or p4 ,inland,p4 or p5,(some guys run p6 )
.3 to .4 mm shim seems about standard here,the Manufacturer includes shimming recomendations for nitro content,ie -under -16% nitro 0.3mm , -20%- 0.4mm(+ _ 0.1mm) , more than 25%- nitro 0.5mm(+ _ 0.1mm).
The engines come shimmed 7.2mm @ 28 thou ,1 alloy @12 thou,1 copper @12 thou,1 copper @ 4 thou. ive kept the 2 copper shims (just a guess,would the copper shims aid in heat transfer ?) .
regarding the glow plug,i had a few discussions here about p3 p4 plugs,still not clear on this one,is the
p3 easier to tune with ?http://www.rctech.net/forum/classic_...ilies/cool.gif
