And take the pet concern seriously. Animals for some reason love antifreeze and if you love the family pet, keep them away from the stuff because it will kill them if they drink it!

So, at the end of last season, I had flame-out issues with one of my engines, so myself and a buddy (who is very experienced, and is a team driver) decided to seal up the engines *just to be sure* there were no air leaks.

We cleaned and sealed up the carbs - that went fine. However, when we went to install new seals on the needles, we had a heck of a time getting the o-rings onto the needles. We were able to do the low-speed and idle screw, but there was just no way we were going to get the seals onto the HSN - we ended up breaking the remaining rings...

I ended up purchasing a couple of new high-speed needles (and more o-rings) from A-Main, since they come with the o-rings installed....

So, I've got two HSN's without o-rings, and a few new packages of o-rings to try this again. Any tips on trying to get the o-rings onto the HSN?

We tried the following:

- lubrication
- using a wet-dry paper to smooth the screw head so there were no sharp points (we didn't want to install the o-ring via the needle-end, since the threads may damage the o-ring).
- heating the o-rings
- pre-stretching the o-rings
- sacrificing chickens

None of the above worked, so I'm open to any other suggestions.

I used the Traxxas Oring kit off amain and stretched the brass tubes a bit on the large end to Fit Nicely over most needles, Slide the O ring on and your Done. Easy peezy with the right tools.

Which other O ring installers did you find on amain ?

Which o-ring kit are you referring to?

I didn't find any installers on amain...just the o-rings.

This?

Hey, I just pick up a B5 from A Main and I am about 6 tanks through so far on my Hyper 7. I was on a trip and my son messed with the carb setting. Kids and tools!!!! Can you help with telling me how to set the carb back up to factory and then I can go from there to start the tuning process and continue the break in? Any help would be AWESOME!!!

Just go back to flush on both needles and i would just start back over since your only 6 tanks in i would just make sure i got a good idle and the needles shouldnt be to far from factory setting i hope this helps.

Thanks, Ron. One of our cat's died last year when a neighbor left antifreeze out. He started acting funny 12 hours later and within 2 days his kidneys were destroyed and he had to be euthanized. By the time you notice something is wrong it's already too late

Antifreeze tastes sweet
I don't suggest trying it.

i need a big favor, can someone measure the length of thier pinch bolt screw and let me know what it is?

measure end to end, top of the cap to bottom of the thread.

Since my engine is currently in pieces (check the B6 thread) I was able to get this for you.

It's a 12mm cap head screw that measures 14.4mm from tip to tip.

thanks man, i appreciate it.

hello Ron,

i just like to say you hit a good thing for the Motors with the B5...
i do Motor testing to find what motors best fit for the Budgets for what racers can "Afford" or looking to spend on a "Motor"
out of 22+ motors i am happy to say your Motors are right there on top!
and what i mean is i know over the years so many Equate if it cost more? then it is the best? not always so....
though "True" sometimes if it is "Inexpensive" sometimes it is "Cheaply Made"
but in this case "Inexpensive" does not mean "Cheap Construction"
and for the Under $250.00 mark we have for Motors that "WORK"
(we had 4 grades,
up to $250.00 ,
$250.00 to $315.00 ,
$315.00 to $375.00
and Stupid Over Priced)
of the $250.00 to $315.00 of the 3 they all surpassed those motors
"Easily" the B5 had the most Grunt of those....
of the $315.00 to $375.00 was "CLOSE" only one came close! and was the Nova .21-4 but still 2 outsurpassed this and even still the B5 had more "Bottom" to Move a truck......

(the Nova had to change pipes/headers for different tracks to get it's best performances the B5 "One Pipe" on the truck for either short or open tracks seemed to have a good "Balance")

and Ironicly???? only one of the 3 motors under $250.00
out-did,out-performed,and had better Mileage than ALL of the "Over-Priced Motors"...????
and the B5 is "One of Them" and to be Unbiased i did not think it could? but it did...........
a pretty tall order !!! keep up the great work !!
(the B5-Pro did not make the $250.00 mark,but it is pretty much the motor now to shoot for,at it's "Price Range" it out-does just about every motor in it's range and those costing $400.00+)

since we found almost "Anything will work in a Buggy" not much on the market in the .21 series "Motors" 90% of other motors you really have to "Stand on the Gas" to get them to Shine that move a "Truggy with Authority" but the B5 in it's "Simplest Discription"
feels more like an "Electric Powerband" with the correct clutch shoes and Gearing......
again only 3 outperformed 99% of the Motors on the market.....i say 99% since there maybe something out there that can for the "Price range" but out of the 22 we have done so far nothihng has really come close?
of the Flood of motors on the Market, like cars
if i "HAD" to pick one?
to recommend to someone that was Un-Modified box stock can buy right off the hobby shop self! have to give it to the B5.....
I run a different motor,but i get Questions all the time?
and what would "I Recommend" for the First motor?
so far the B5 is just one of those "Motors" you dont have to Guess about??
like back in the day?? if you bought a Nova you were good !!
now you just "Do Not Know" and one has to ask themselves?
ok do i buy a 21-4? a Bonito? a overpriced FMS? a Bullett? a VOX?? a Orion??, a O.S.?? how do i Know? you dont? and any "Good Driver" can make a Motor look good!!
i mean for $400.00 motor it better work?? and when they do not?
it's a big drop of coin for something that was meant for a Buggy? and not so much for the Gearing and Grunt of a "Truggy"
to many $400.00+ dollars is allot, to many,in this Economy even still 200.00 is allot, but it's not as bad to know for $199.00 your going to get a motor that "WERKS"
again for a .21 series Motor that is Unmodified and in it's Stock Form
i only found 3 motors out of 22 that worked,and One that really had a feel like a Motor that had a bigger displacment!! a standard B5

thanks for the tips on the antifreeze, I had heard that before but forgot as i dont even own a crock pot, so yall say dollar general has them cheap? and ya, there is a few pisky cats around that like to climb on my new car.....haha j/k no but realy....

I can't get the carb out of the crankcase. Any ideas?
