Hi
My savage doesn't want to suck fuel even when i put my finger on the exhaust end and start it with roto start. What can I do?
Also what do air bubbles in fuel pipe indicate?
I'm new to rc models so please be understanding.

Thank you for your help!

Heywodja

Maybe the fuel lines are reversed?

i have had to actually pull off the line from the muffler and blow on it to get it primed try that and see what happens

Air bubbles mean one thing AIR LEAK check the lines (I would put new ones on) the tank, and the Oring on the tank cap [sm=shades_smile.gif]

And just for FYI it doesn't suck fuel the exhaust presser pushes the fuel to the carb [sm=shades_smile.gif]

No. It does suck fuel. The tanks are pressurized only to augment this.

If the motors been sitting for a while with fuel in it, it may be clogged with oil. Try pulling the glow plug and the fuel line from the carb and blow some compressed air through it while rotating the flywheel then try it again.

Well ok it sucks fuel form the carb into the crankcase but with out exhaust presser it will run supper lean and stop running. Do you agree? [sm=shades_smile.gif]

umm when it wont start be more descriptive it can be anything from no fuel getting to the carb, bad plug, bad starter battery etc...

hi im back again
THANK YOU ALL FOR HELP!

SOrry for being a bit dumb but the truck has been sitting in my room for few months and i think  that this could be the problem too regarding why it doesnt start. The glow plug fine i checked it by the way
SO any ideas how to clean the engine or get the car to its normality again, restore it or anything?

thank you so much for your help, i really appreciate it!

carb/brake cleaner from a auto store works wonders on cleaning nitro engines
and its damn cheap (well at least in the states)

i have an s25 engine from hpi and if it sat without attention i noticed that even when using after run the high speed and low speed needles along with the inside of the carb will get surface rust. and that in turn will clog up fuel passages. it is best to have it cleaned out or you can clean it yourself. you have to remove the carb to clean it.then disassemble the carb and clean it thoroughly. stuf you can use to cean it with is: some use wd40, some use brakleen, i use la awsome degreaser and a toothbrush, then rinse well with water(hot) and dry it well( a hair dryer woks well for drying as it heats it up enough to evap water in spots you can't get to). after you clean i would a little after run oil to lube the slide portion of the carb. then reassemble the carb and return to default settings. if you don't have your manual, let me know, i have the pdf with all the info.

Cheers guys, I just decided yesterday to get my Savage going again after 7 months of it sat around. I had this exact problem with it not getting fuel into the carb, after a few unlucky mouthfuls of Nito Fuel I managed to get it running and it's perfect!

well should make a new thread as most people read the 1st post, and ignore the rest.

but sounds like your tune is off, and it might be getting too much fuel into the engine bogging it down.
