Canadian tire sells carb kits for them for about $20.00. The kit comes

Re: More Questions
Canadian tire sells carb kits for them for about $20.00. The kit comes
with a new needle and seat for the float and a new accelerator pump.
A kit can do them wonders. Things like the pump do wear out.

Re: More Questions
Mike this is a new carb but I guess that doesn't mean it was set up
correct from the factory, I did have the idle very low ( I was
marvelling at how well it idles with the computer out of the loop) and
since that time I have bumped it up to about 800 rpm from about 500 or
600 rpm. That seems to have solved the minor stutter when starting out
from a stop. Thanks

correct from the factory, I did have the idle very low ( I was
marvelling at how well it idles with the computer out of the loop) and
since that time I have bumped it up to about 800 rpm from about 500 or
600 rpm. That seems to have solved the minor stutter when starting out
from a stop. Thanks

Re: More Questions
800 is closer to what it should be. I try and keep mine between 750 and
850 rpm.
If the canister purge valve is bad, it lowers the manifold vacuum at
idle which also can make a stumble.
