Hi.

What plug and how much nitro are you using?

Sounds like too rich LSN and/or too cold plug.

LSN adjustment: http://www.neobuggy.net/modules/news...p?storyid=7253

I use 25%
Stock plug i believe.
Its not LSN, and I doubt its the plug temp, its a rotten plug.
I need to know if I can use GRP plugs, cause its all I currently have in stock.

I had the same problem with my p5, the plug was DOA, haha. I really don't know if the GRP plugs work. Is it a turbo plug engine or a standard plug? That would be the factor I think. If it's a standard plug then sure, if it's a turbo, you might need to hear from Monty on that one. I don't run turbo. Good luck man.

Problem solved, found an OD 99t sitting an my old Caster engine. Fired right up, had a fast idle at 230-240. Richened the LSN and leaned the idle, setteled for a steady idle at 220. Purred like a kitten.
Had it running through 2 tanks stopped it about 10 times and let it cool down a bit, took like one hour, gonna spend some time with this baby before i unleash it on track.

Houston, many thanks for the valuable advice.

I had the same problem too! Changed to a 97t and it was better. Sucks the plug wasn't right to start with though. Breaking an engine in hard enough as it is.

The issued plug sucked, sure. Still, I'm so glad I didnt start to mess with the needles in order to "sort it out".

Never really thought about it till now. The plug in my first FMS was dead also. New from Nova in the bag. I cranked on it for maybe 10 seconds with no luck. Pulled the plug and no life. Bummer.

A friend told me Novarossi runs the +4 engines for a while before shipping them out. Just wondering if you've heard the same thing?

Not actually ran , but turned over fo just a few strokes with the lapping compound installed . However it does not remove any of the cross hatching from the honing and i am pretty sure they do this at a certain temperature for proper expansion .

With the "HES Tuned" P5XLT, 9853SS, OS P4 glow plug, 6.5 restrictor in a RC8B stock gearing it was out of fuel on avg 10 - 10:40. TBH, I never let it run out of fuel, I just pit at those times and the tank was close to empty. Should I try a 6.0 or 5.5 restrictor next? Or leave it alone? Its still a whole lot of motor for a buggy. I want to get the hang of this 5pt, Its bad A. I dont want to have to invest in a different pipe though.

What's wrong with that runtime?

6.0mm works very well with the 5 port in buggy , btw , that pipe on that engine has gotta be a handful !!! 9901ss/41005

Looking at getting the Plus 4 team with HES mod
I drive Mugen buggy and like a nice even power delivery but not a big bottom.
What pipe and header you recommend
I used OD97T plugs in my first Plus 4
I run 25% fuel with 12% oil (10,2)
what would be a good combo and any other info about the above that you would recommend.

hey Monty, thanks. I'll let you know when im ready for that 9901 then. I guess the 9853 is too strong on bottom end. It is awful if the track doesnt have a clean race groove. I dont think i have a 6.0mm either so i'll get that from you also. Probably be friday or saturday. ok? Also, do i need to richen or lean the needles with the 9901?

BTW, nothing wrong with that runtime, and the motor pipe combo i have now would be perfect in truggy. I hope with the 6.0mm restrictor and 9901 pipe that I could get a little more run time and smoother power delivery. Thanks for everything Monty.
