blaster doesnt run right
- Thread starter Blastinator
- Start date
ok. the one I pulled off at first was thick and black and wet, and the one I had lying around was just thick and black.and its the br8es
#230 is no way big enough, the FMF Fatty calls for a #260, Air filter one size more and 32:1 one more again.
Start with a #290 main and plug chop.
Before you make the plug chop run it is important that the float level is correct, the idle is set correctly and there are no air leaks in the system, otherwise the smoke ring may lie about the AFR.
WHEN ALL OF THE ABOVE ARE CORRECT PROCEED WITH THE FOLLOWING.
Warm up motor to operating temp.
Fit new B8ES plug, ride WOT through the gears and hold WOT in 5th or 6th gear for 10 seconds, or as long as you can safely.
Switch off the motor and pull in the clutch, apply brakes to come to a stop quickly.
Take the plug out and replace the old one for the ride home.
Carefully cut the threaded end off the plug to expose the insulator.
There should be a smoke ring of a cardboard or biscuit colour around the insulator.
If it is non existant or a very light colour, you are lean and require a larger main jet.
If it is a lot darker you are rich and may go down a size in main.
I prefer to run a little on the darker side, I may loose a little power but it is worth it for the peace of mind that I won't need a rebuild so soon.

This is a good to go plug.
This one is a little rich, but I would run it, I like to be on the safe side.
Ok. So it started up but after a while still bogged and did the same thing just not as bad. And another thing, wen I started to bog if I shake the quad it revs rite up.
Do you have a good gas flow going to the carb? If you shake it and it runs better, it may be that...
Yea I've checked that a few times. I've even drained the fuel through that gas line and it flowed nicely.
how much fuel did you drain? if the vent on the cap is clogged then it will drain nicely until the tank gets vacuum locked then it will stop flowing. try to fill at least a snapple bottle size bottle
that sounds fuel or loose electrical connection to me.
you've already checked fuel flow to the carb, it could be the fuel sloshing around in the bowl, either picking up more or less
check/set float height......

check all electrical connections for loose/dirty
If it improves when you shake it there are a number of things that could be wrong.
Low fuel in tank, delivery tube above the level.
Float level set wrongly ,allowing fuel to flow when disturbed.
Sticking float.
Air leak made worse by movement, this happens sometimes around the carby boot.
