EB Mods JS Engine

jbright is right, HS needle too rich. these engines tune backwards from most.
set the bottom and forget it. tune with the top.
found the same thing yesterday with a buddies full mod. kept flamin' after it started, notice raw fuel spitting out the stinger. started leaning it got better and better. then sat there and idle for like ever. threw it down busted the throttle went like a banshy. no more probs the rest of the 98 degree 55% humidity brutal day. very nice engine. mine will be on order soon as i can dump these speeds.

BTW Matt, when you made a couple laps yesterday the steering servo horn was stripped. That is why it wouldn't hardly turn.

becoming very frustrated with js motors. i have a race prep that will not hold a consistant tune. i had a full mod that the silicone came out of the crank. had my supplier send it back in to be re-worked and we were told they would be overnighted to us last thurs. so we would have them back in time for our first summer points race. i have yet to see my motor back. before the silicone came out, i was pleased with the full mod, but i believe the race prep will be going on ebay. after the full mod is used up,( when ever i get it back) i am going back to my old engine manufacturer. having the motor pre-broke in is great, but it is not worth the head aches i have had.

I have almost a gallon through my full mod. The Hut was canceled today so me and my buddies just burned nitro on the track all day. I am going through P5's like it's going out of style. I will run a quart through the engine and give it a rest. I go back to start it and the plug will be dead. The coils are severing up inside the plug.
I have been having a hard time keeping this motor from stalling. If I come in for fuel and don't keep it clear than I will flame out as I drive down the ramp. The motor is running strong when it's running, temps are averaging around 215, it's got tons of top end. It's blowing smoke coming out of turns all the way down the straight. The coils look dry with some oily soot around the tip of the plug.
Here is my tuning rational and probably where I am going wrong. I feel like every time I come in for fuel the motor loads up. I have been leaning little by little on the bottom end to slow the fuel going in at idle. Should I be leaning the top? Leaning the top would limit the total amount of fuel going into the engine. The reason why I went for the bottom was because I felt like the top was clearing out well and the running temps were good.
I used all my P5's so a fellow driver was kind enough to loan me a P4. That was the last pint I ran on the motor but it was running real well with the P4, it never flamed out, idled well and flat out ran awesome for a good session of driving with my friends. These ailments I am suffering from are caused by me. I just need a little help from you guys to get me on the road to a solid tune. Maybe keep running the P4 and see what happens?
This motor is very, very fast, I have said this before but I have not seen the top end fully unravel yet. With the 086 pipe I have to drive it aggressively to keep it on the pipe. Nothing crazy, this thing just wants more all the time. The bottom end is a little soft, the mid comes on real strong and smooth and then it just screams out to the top all day. Is this the general consensus with this pipe and motor combo?
Let me know what you guys think about my plug popping and load up/flame out problem. I was running P5's with Byrons 25/11, temping around 215 at the Hobby Hut today.

yes tony is a team driver. that is why he is not posting any of his problems on the forum. i, on the other hand, am not a team driver and am getting frustrated at not having my motor, especially when we were told we would have them over a week ago. and i am not getting them at cost. we have a couple big races coming and i would like to have more than just my back up motor just in case.
#806
maybe if you used the team email like your supposed to i would have. RCT is NOT the place to discuss team matters. I have a email address and phone number for that.

me being on here daily has nothing to do with the fact that team drivers have a team email addy and are supposed to contact me that way only. This is the only way for me to keep everything on file and share info with appropriate ppl.
