i finally finished my 20% that i got to break in the engine and switched to 30% man did it make a difference... like turning on a switch, and unleashing hidden power. unfortunatly that power went to my cb and stopped...

the mesh was set by my lhs using the paper method and worked fine untill now. but during the run i noticed oil aroundthe back of the engine and rear shock tower. i ran it with out the top to see if i could find where it was coming from but it came to no avail.

as u can see int the pics my cb is still in the truck...(just in little pieces)[]

any ways if u have any comments or tips i will try just about any thing right about now, im getting sick of not being able to just go drive...

It looks like your problem is the fact that that is not A hardened steel CB. The Robinson Hardened Spur needs to be run with it's bell. I have both of Robinsons' Spurs sitting in my tool box, since I don't use them any more.
With proper mesh the plastic spurs won't strip, and they are lighter, and offer more flexibility in gearing. I've run 2 Gallons of 30% through a Collari .30 with the same plastic HPI spur with no problems.

Was that a Robinson Racing hardened bell against that spur, or was it an HPI bell? That silver 'dust' that must have been piling up for the last few tanks was a good indication that the mesh was getting loose and the CB was wearing down. This happens with a hardened spur, even with a hardened bell eventually they wear down.

If you want to keep that spur get yourself some hardened bells by OFNA. The ones that fit the LX will work. If you stay RR you can only get a 14 or 16 (or is it 13 or 16?) but OFNA makes the whole range. You will also need the 5 dollar OFNA shim kit to ge tthe bell setup in the right spot.

Does the mesh need to be adjusted on a regular basis?

ed260z

If you used Lock-tite no. But sometimes things get loose. So you should at least check it every now and then.[8D]

ETRNL

all of the silver dust was from the last half tank.(i only fill it up half ways to avoid leaning issuse with stock tank)
as for the cb it was the stock 15t i think anyways do u have any links to what urtalkin bout???

ed260z

Tower Hobbies sells the Ofna CB's.

ETRNL

any suggestions on gearing while im at it??

ETRNL

also does any one elses header pipe look like that, covered in burt orange junk????

ntloser

I have that orange gunk on my header pipe. Mine actually looks a little more brown but not as much.

ETRNL

i just wanted to see if its normal or not

ntloser

Well, even though I have it too that doesn't mean it is normal. I am totally new and come close to damaging my engine eveytime I try to tune it.

Well that was definitely the problem... That 15 is a stock CB. You CAN'T run a stock bell with that steel spur for the reason you've just seen. Get the Ofna hardened bells and shim kit...

ETRNL

will a 14 or an 18t cb mesh w/ a 49t spur gear???

fastcrash

once you learn how to set your mesh, you will realize that the rr hardened steel spur is a waste of power. the stock spur gear is plenty strong for any engine you can bolt onto the savage. your steel spur is much heavier than the stock one, which is robbing you of power. by going back to stock you will se a much bigger power gain than you did from the 3o% fuel. theres my .02

ETRNL

well i put my 18t cb on and put my stock 49t gear. since as soon as i got the truck i replaced the stock spur gear so it brand new.
thanx for the advice

ETRNL

also for anyone else that has the burt crude on manifold... i found that the actual grommet on the exhaust of the engine was not the same size as the manifold.. so i didnt have a sealed exhaust...
i fixed this by "shimming" it with some F4 tape under the grommet bringing it to fit snugly..

Something I'm starting to notice about my Plastic Spur with the Collari, is that it's melting just on the inside of the slipper pad.
I'm wondering if anyone else has noticed this?[&:]

cleffdawg

to me that would indicate that it's a bit too loose and slipping too much. Just a guess however and i'm sure you'll tell me i'm wrong.

sm954

I burned up a spur gear on mine in the same way, the slipper was entirely to loose and melted the spur gear!!
The more that slips the more heat it generates!![:@]
