Sytella 4T stall issue solved! woo-hoo!

Post by EvilNerdLord »

ever since I got the scoot there have been times she's acted starved and quit on me, I was thinking it must be the CA emissions stuff vapor locking things because every indication pointed to it...
runs, starve, quit, pop cap/look/ fuel ok, replace, run, starve, quit, repeat...

WTF?!?!

replaced cap with 2 stroker, ran ok but over fill and get a mess as gas aqirts out of the vent...oops :oops:

replaced inline fuel filter (crap, original was still there!) only available was a generic bell shape at least twice as wide as original aaand problem got magnatudes WORSE! :shock:

realized FINALLY
1) the black feed line was too long and 2) the grey output to the carb was also (both by about 1/2") and 3) the 'bell' shape of those filters don't fill high enough to flow into the outlet. :?

trimmed lines, replaced with a small bell filter (actually slightly smaller diameter than original) and TAH-DAH! problem fixed!

did a 62 mile run from marysville, ca to bangor ca WITHOUT so much as a hickup....

if your experiencing the same stalls, check line lengths and the filter bell shape, it may not be filling to a level to flow into the outlet.

There's a fuel filter inside the tank at the petcock, so you really don't even need that inline one. My guess is it's there to act as an adapter between the 3/8ths fuel line from the tank, and the 1/4" line from the carb.
I got a metal airline adapter and eliminated the filter.

I don't have the tool for the 'in the tank filter', and isn't it more of a strainer than a filter? (more porous)

No, I was saying that I run without the in-line filter.

yes, I was actually thinking at the time 'do I really need this?', but I wasn't sure if the in tank one was fine enough to be a filter by itself.
