I havent read all the post so i may be jumping the gun but have you tried having a look in the carb for any debris ? also as before stated 15% oil is a little high.. Try a fuel with 12%, the engine will run cooler and performance will be better

try to turn the carburetor a little bit where it bolts into the engine, and also, try tapping the screw from the opposite side you removed the hex from.

Definetely replace the clutch springs and replace the clutch shoes if necessary.

What he said. If your springs are worn, replace them as well as the shoes. Get some Mugen 1.1 springs and Mugen shoes.

whats the difference between the spring numbers like 1.1 compared to say a .9 and what is the best way to install them as my old shoes seem to be slipping off out from the pins leaving the pin holes with excess room (not flush with pins) as they should be.
if i get new ones how do i make sure they click right in first shoes replacement mind you so i dont wanna stuff them up any advice much welcomed thankyou...........regards Aaron.

1.1 spring is tighter than say a .9 spring, and will take more force, or in this case, more RPMs to engage the spring. You usually want to stick with a 1.0-1.1, I would only suggest a .9 spring on a very high grip track.

Sounds also like you could use some new springs/shoes. You probably have worn out shoes, and the springs have probably worn out trying to engage the worn shoes . Go ahead and get some Mugen carbon clutch shoes and 1.1 springs, and replace them to get everything working right again.
when you reinstall them, make sure that you slip the spring on the shoe first, then, using a screwdriver or pliers, push the back of the spring back while applying pressure to the shoe. The spring should slide down into the cranknut groove, and the shoe should drop into the place. Hope this helps!

Haven't heard from you in a while, how are your engine troubles?

yeah im still having the same trouble as i did before (can't get a full tank yet)
so um im not sure it just seems to rev really high when i pull in after accelerating or just plain driving , so really high reving and over heating getting to about 300 fh on the track and got to 360 fh on the road outside after open throttle for few runs, so um im confused about this engine's troubles but once clutch shoes are here with springs(getting them sent by my xray dealer in australia) then i shall keep at it, im actually selling my kyosho inferno and my losi xx-cr on ebay and advertised on this site http://cgi.ebay.com.au/ws/eBayISAPI....e=STRK%3AMESE%
3AIT&rd=1so

if you might want to hot them up and sell for profit or something ill take $600 aud for you if you want them or know someone who wants them plus postage costs. which ill work out and charge by exact rates.
i can get a team losi xx-4 or xxx-4 electric i seem to have to many dramers with nitro i might just keep the xb8 for fun, buy a new engine and see if i get more success out of that other wise i think ill race 1/10th 4wd electric buggies with the new 3600 mah batt packs nice considering when i ran electric 2000mah packs were illegal to race with apparently.
also i seem to get a load of nitro fuel in air filter to umm that tells me its too rich but why is it running so hot and over reving it doesnt make sense because when i lean it out it seems to start struggling like i mentioned in the previous forums ,it makes the bog sound like its not goeing properly ,not getting fuel to burn, so maybe the sparke plug is getting wet early filling the engine with unburned fuel flooding build up which would explain fuel in filter it seems the engine isnt firing properly.
to be honest im a bit confused with it so i think i might end up selling the xb8 if the new engine i buy does the same thing lol.

also i might add is the final result of this particular engine is that when i get it leaned out to max performance going well,accelerating right through to full throttle it's great but then when it heats up a bit to around half tank time it starts the bog struggle thing.
so to sum up the problems i cant richen it any more because it will sputter (too rich) and cant lean it out anymore (overheating and lack performance)
but the thing that gets on my goat is after all that it starts that bog bog bog sound which by that point after tuning ive had enough of the damn thing to be brutally honest.lol so the things that make you go hmm- this is one of them

In my MANY years in the hobby, I've never heard anything like this. It sounds like you have a TINY ASS air leak somewhere, that's all I could think of. Swap your tank, lines, and all filters. Seal the backplate, head, and carb base. And try EVERYTHING again. I don't know what to tell you tuning wise, seems like you've tried everything. If all else fails, I have a nice RB engine I can sell you for a good price, if you're frustrated with this engine. It sounds as if you got one of the earlier ones with the carb trouble, as SpeedBump described in an earlier post.

Anyway, PM me if you just want to start out with a new motor, or we can go back to the drawing board to get yours running right.


Anyway, best of luck selling the older K Car and the buggy, I know a guy who may buy up the buggy so keep your eyes peeled on the auction.

Good Luck!!!!!

Downunder your pipe will fit perfectly, and if you are interested, I have a Losi XXX-4 G+ kit if you wanted to swap something? It's new in box.
