New HS motor very rough idle

What kit/gearbox?

Bought from BoyGoFast on ebay which I won't do again as it's not the quality I had in mind. .
so you have the infamous J.L. Hoot gearbox or similar

you have my sympathies and there may be one or two people
who got theirs to run for any length of time at an acceptable level

i have one as a curiousity but would never be foolish enough to
actually try and use one on a build

you could buy a Grubee gearbox to salvage your kit for about $120
 
Oh so that's the dreaded Hoot gearbox I've read about. Hoping for a healing
with the EZM.

Do you know what "hope" is? It's the rope you hang yourself with when hopes
are dashed.:sick:
 
4-Stroke gearbox

Hi I am familiar with most of the gearboxes available, if you put up a pic, I can ID it for you.

Gearbox ID=JL Hoot type

Hi IF you have the one in the pics, there are about 3 variations of it. The first type was what I had, it ran about 50 miles. The second and third types can last a while. I do have plenty of parts for these, tho I do not know who else might.

Go ahead and build it, ride it, and enjoy it, and if it breaks down, try to fix it and keep going!

As of yet, the friendly people at Brand X are not selling gearboxes, just kits, so Ride On!

mine's different

The Boy's pics are showing a different unit than what I have. I get a pic up later today. What I like the least about mine is it's only 3 - 1 reduction which isn't nearly enough.

is BoyGoFast still selling what you bought?

if so please put up a link to a current or finished auction

is it chain drive inside?
 
Don't have link to auction, it's been about 6 weeks.

Yes there is a chain inside and 3 - 1 reduction.

After couple hours of run in, tweaking the fuel screw and smoothing out bent wheel and sprocket wobble issues it's running well.

Only need about 5 mph of speed then give it the gas to engage clutch, then it
takes off on it's own just fine. Opened it up and there's minimal dust from
clutch so I know it's engaging and not slipping.

And now I'll attempt to attach pics.
