sorry double post

Thank you for the reply.

I have checked my end points several times and the slide does not over travel, nor did it on my old JS engine, where I had the same problem. So unfortunately your proposal does not solve my problem

I have 3 JS Racing engines for sale if anyone is interested.

JS Racing 23 Race Prep Hellfire engine: New in the box sealed in plastic $ 175

JS Racing 21 Engine new in box: $170 w/ Dynamite 086 pipe

JS Racing 21 Engine new in box: $170 w/ Dynamite 086 pipe

$300 for both 21 engines and 2 pipe combos.

Your slide may have a burr on the idle screw groove. You will need to remove the slide and check for burrs. Check the inside of the carburetor body as well. If this isn't the problem then maybe contact the factory direct at:
[email protected]

If this is the problem it usally happens when adjusting the idle screw in the clockwise direction, the screw hits the slide which has spring tension from the throttle arm. It's good practice to always open the throttle when adjusting the idle screw.

When you are inspecting the slide also look at the inside carburetor body to see if the slide is being pulled straight. The inside surface will have wear marks from the slide which should be centered.

Ryan just an update, Chris received his replacement engine.

BIG thanks goes out to Aaron Pucci

Did you try this new number 1-800-678-1037 or [email protected]

anyone have tuning settings for the .23 at 6000ft above sea level and dry climate? Runnin the .23 Hellfire Race Prep, Had it dialed in once then something happened and now it wont run for more than 5 secs. Just looking for a base carb setup at 6000ft asl. Thanks

PM sent on JS Engine and pipe , do you still have them for sale ?

Please check the piston skirt isn't broke on the exhaust port side. On some engines at TDC the piston skirt travels past the bottom of the port and will catch on the down-stroke and break.

Sorry Bruce no engines or pipes in-stock. Try Absolute Hobbyz or A Main Hobbies.

Hi Ed, do you have an ETA as to when your new engine will be for sale? Thanks, Jim

ETA around Christmas / New Year we should have production started on the new .21 engine. Team Drivers and Hobby Shops will have samples to test in Mid-October. This engine will be completly made in the USA, with some of the parts machined in-house at EBMods and other parts out sourced to machine shops.

As we get closer to testing I will have updates and more info about the engine.

Oh and I have to say I'm VERY excited about this,,, I wish we could speed the process up but small steps first, with lots of testing. It's an amazing feeling everytime we finish a part!!!!!!
