Has anyone else tried the odonnell 97t plugs, my motor ran decent with these plugs but seemed a little hard to start and cold natured. Could this be because of the97t plug, also i got 9:20 min. a tank on a dusty slick track, they hadn't watered that day using a 7.5mm restrictor, could the p5 get better fuel milage or should i go to a 7mm restrictor. I have ordered some p5's to try out next race. Thanks for any info....

The recommended plug is a P5. I use P5, 7mm and an 086 and the shortest run time to date now is 10 min 40 sec till dry with a race prep in my buggy

i won one of these blue head js motors in a raffle, is it true that they all come ran in , it feel tight

NO!~

There are 3 versions. 1. Box Stock 2. Race Prep. (Broke in) and 3. Full Modded and Race Prep. It should say on the box, all mine have.

Mine is etched on the side of the motor where the mounts screw in, "Full Mod." See if yours has an etching if it did not come in a box.

My experience is that the motors don't need much break in

anyone try this motor with any other pipe really besides the 086 and the 9901? i am thinking of trying this motor (stock version) and i currently have an OS 2050. how would this pipe work with the motor? or should i just buy an 086?

I run the Losi RE11 is great

I am running an RE10 and it's awesome. Great power and fuel mileage in my T 2.0. I was running an 086 and it was good too. Somewhere in this thread you will find which pipes definitely don't work.

os 2060, 086, 9901, mugen 1005, and the 2041 ebmod pipe. these have all been used with great success. my choice is the 9901 or the 2060, the 1005 and the 2041 make stupid power from idle to infinity, some find them hard to control.

engine has very strong bottom end smooth delivery up through the power band. choose pipe accordingly.

another attempt to tune the engine. no luck at all. the engine does not seem to respond to any needle movement (rich, lean, HSN, LSN no mater what we did engine just bogs on straights). idle is ok. acceleration is great but top speed issues continue. The only thing I can think of is an airleak in the engine itself as I tried two carbs but it does not sound like an airleak.

//edit - got possible cause identified will let you know if fix helped

If you don't think you have an airleak, what's your clutch look like? I have had flame out/reliability problems and chased the tune for way too long only to find the clutch was smoked.

I had the same issues myself today. The car would start up then as I was trying to warm them up they just flamed out. They ran like they had a bad plug. When I left the ignitor on they ran fine.

How long have you been running this engine for? Sounds like the low end is rich but that is a big assumption on my part with limited information. What does the plug look like? The best person to talk to about your JS is Ed Bridges, I have talked to him on the phone several times and learned boat loads every time. Give him a call:

Sales and Service: 570-779-0646

Sales: 570-851-2954

He has picked up on a Saturday before. I doubt you get him on a Sunday.

I had the needles all over the place trying to get this to run. From lean on the bottom to rich on the bottom.

Does any one know the factory settings?
