ok...the motor is a nitro star .15FE.

my next question is where does the vent for the fuel tank hook up to? it wont start because the tank is not pressurized, therefore its getting no fuel....i'll work on the pullstart but i need to know how to get fuel to the engine....

thanks alot, any help is much appretiated!

If it's doing that while it's running, it sounds like the motor is running too hot. Try backing out the high speed adjustment 1/4 turn....

If it's not the motor, it may be the gear backlash. Adjust it by loosening the motor mounts. Place a strip of paper or part package plastic between the gears and re-tightening the motor mounts.

If it's not either of those, PM me and I'll help.

pinging could be the end of the rod in the crank case. :(

The pinging is likely the clutch bell housing. This is not abnormal, but make sure everything is set up like it should be just in case. As far as the fuel tank, like it was said above, there is a hole in your exhause pipe, the fuel tank pressure hose goes there.

I'm not sure that pulling the pullstart assembly will tell you anything. It's not likely at all that this is where the sound is coming from. There's nothing in there but a plastic spool, a spring, a one-way bearing and some pull-start string.

If you flick the Clutch Bell with your finger, you whould hear the same sound you are hearing when you pull the starter cord. As long as it's not wobbly, it should be fine to run.

On a side note, if you do decide to pull the pull-start assembly apart and clean the one-way bearing, make sure you lube it before you put it back together. Too many people (me included) when they first look at one of those figure it needs to be squeaky clean to properly work. Not so. As a matter of fact, there are actually manufacturers that make specific oil for one-way bearings. A little After Run Oil will work well though. If you are looking for a good cleaner, try soaking it in Nitro for an hour or so. Sometimes that does the trick.
