Honestly, it flat out distracted me while I was trying to drive. After the race I found out that angry sounding stupid fast engine was a race prep.

My setup: P5, RE10 Pipe, 30% Byrons

High Speed needle is 2.5 turns out from bottom or half a turn in from flush.

Low Speed is 3.5 + turns from the bottom or 1 1/4 in from flush.

I put a new plug in a few tanks ago, it currently has a shiny bronzed look on the face, the coil is greyish red, looks shot and the glows weak. These things are getting expensive...

I notice when I go to pit the engine is idling high, like the low speed is lean or my idle gap is too big. This only happens when I have the engine hot because I am worried about it flaming out when I am warming up the motor on the box, it's from one extreme to the other. Temp wise I am around 240 on my gun, for what that is worth. I feel like it's the low speed being too lean but only a few hour turns ago I was told I was too rich, pulling filaments out of plugs, browned plug faces, and flame outs. Now I might be too lean. My fuel mileage went out the window too, I needed to stop twice in a 20 min main. Two weeks ago I stopped once and still had fuel to spare. I am lost in the sauce here! Granted I am not flaming out and my truggy is jumping everything with ease, I know something is not right. This all stems back to a race prep blowing the doors off me and my Full Mod ain't turning heads like it should.

Hey guys, are any of you guys having trouble with your HSN? When I first got my JS I noticed that the 'O' rings had broken and coming out of the top of the needle. I decided to get some new 'O' rings and installed them myself. What a mission! It was super tight and it did the same thing with the rubber coming out. It is also very tight to tune now, very, very tight.

Other than that, I really like it. I was getting 10+ minutes in the final the other day using a GO 2072 pipe with plenty of power :)

Thanks again

I saw a head snap off of a team drivers motor last weekend. He said it was the second one that he broke. Has anyone else had this problem.

The new JS flywheel, clutches, & springs look good Ed. Cant wait to try them out.

I still dont understand where all this complaining is coming from. Customer service doesnt get any better than this guys! We are VERY lucky to have Joe and Ed answering all JS engine questions here. Dont listen to the haters...these engines scream!

bopracer,
I am sorry to hear this... I inspect and flow all the carbs and usally find this problem before they ever leave the shop, but I guess this one stuck by me. Are you bottoming the HSN out when the O-Rings tear?

Ive had more TQ and Wins this season than ever before and fighting an ARMY of Werks B5's with my full Mod JS. The tide is changing though and I think the Army is starting to DEFECT!:nod: If I cant get any shops to carry the engine here locally I may just have to become a dealer myself and buy a few. I would have no hesitation in doing so. As a matter of fact Ill be giving Joe a call in the morning to see what it will take to do so.:eek:

Not many other engine companies can you call the company and actually talk to someone who knows what they are talking about and will help you as much as they can. JUST my .02.

It would be nice if Cuddy could come in here and post and maybe apologize for the multiple post about the engine issues he was having that caused people to panic. When the engine problems were caused by his actions.


*** NOTE *** please NEVER bottom the LSN and count the number of turns out. This will damage the emulsion tube (spray-bar) This was not the issue with FCuddy's engine but I needed to point this out. Always set the LSN using the Flush with throttle arm method.
