OK, thankx for the info on that.

Well, I just got the engine.
As I posted, I got from someone that had it unused, in the box.
But, it wasn't sealed on a plastic bag(like other engine I did buy in the past)
Well, it looks new, dont have the slytest(SP?) sign of use.
Anyway, my problem is, the crancksaft have some .5 mm play, on its longitudinal axis. So, I can pull and push the crancksaft on it's "housing".
Is that normal ? Comparing to the other engine I did buy, it feels strange. The other was very tight in every "axis", if you know what I am trying to explain...

Was that clear ? Is it normal for this engine ? Or even if it isn't the way every CRF comes from the factory, can it be used that way ? (I know that, with the collet and flywheel, that play won't be present, but...)

Ok, hope I can sort this out, So I complaing with the guy or I mount it fast

Thankx guys!

Mine is like that and I don't have issues with it. When I fit the clutch the nut pulls it to the front anyway.

Mine is like that to. There is nothing inside the engine to stop it floating, only after the flywheel is attached does it stop moving.

The engine is not sealled in a bag either just wrapped in bubble wrap

Cheers

The play in the crankshaft is absolutely normal, the contrary is not normal, it means there is something that binds or is not centered.

The crankshaft has play because the ballbearings are straight and centered and the tolerances are very tight, this means that when the engine is running there is no power lost because the shaft is too tight in the bearings or putting pressure on the bearings because the bearings are not centered.

Bad tolerances are when you have to use a hammer to knock the crankshaft out of the case or use a screwdriver to pull the liner out...

Once you install the clutch, it will remove the play in the crankshaft.

Thanks for that Nano,

I've now found an on-line shop that sells both O Donnell and Tornado and will post it, I've always used Tornado in the past, is there anything to choose between these 2 with the CRF?

Default Using a Spektrum Temperature Sensor with CRF

Because the combustion chamber bolts on separately on the CRF engine with an extra ring of bolts, what is the best location for the Spektrum temperature sensor for the most accurate measurement, where the cooling head meets the crankcase or the next row of fins up which is adjacent to the glow plug? It just seems a bit tight at the cooling head/crankcase joint for a good reading.

Diesel Racer,

From the two fuels I guess O'Donnel would be the best choice.

For the temp, we only go by measuring the temperature of the glow plug with a temp gun.

Both Josh Cyrulk and I used Tornado fuel at the 2006 ROAR Nationals with great results. I have no doubt that Tornado fuel and the CRF engine are a great combination.

Nano & Rick,

Thanks for the feedback, I think I'll stick with the Tornado as I've used it before.

Can any other glow plugs be used on the Wasp, other than the Team Orion $10 plugs??

I am currently using the Ninja plugs. They seem to work quite well. I have also used Novarossi and OS plugs. Don't know why they all worked but they did.

Guys I am thinking of getting a Wasp 12, but now I am seeing the prices dropping on tower, but I am not sure if it is the updated Josh version or the old version without the updates that they are trying to ge rid of, from what I have noticed the old version part number ORI80000 and the Cyrul version is the same ORI80000, how would I know the difference when making a purchase online???

My fuel choices here are very limited(Itīs Byron or ... Byron. With some good contacts I can get Sidewinder, on large packages ...)
But, a LHS is selling Trinity now. Itīs 8% lubrificant. This should be a better choice to use on the CRF, no ? (than Byron, I mean)
