Long story short, I bought a used silber turbo with redline controller and had it installed on my sled.
Pre-turbo (Engine got a full rebuild two or so rides before the turbo) the sled would start within two pulls all the time. Now it’s very temperamental when it comes to starting. If I am riding around and shut it off and restart almost right away it’ll flash up after a pull or two. And if it sits for long enough, sandwich break it’ll usually start within 1-2 as well. However, it doesn’t consistently start well.
Could it be an issue of my fuel pump going bad? I am thinking it’s not the filter cause it runs well once it’s started
I was running 50:50 94 and av, going forward I’ll just be runnin straight av
As far as numbers go I was 10#, 11.2 afr and 8300 last ride, however my prim spring was broken
thanks in advance
Edit: my mechanic had installed a regulator in the fuel return after the fuel pressure guage.(this was when he did the turbo) When it was really hard to start I’d have to pinch the line under the fuel pressure guage and it would usually fire after three-four quick pulls. When I say quick I mean let the cord go in 3/4 of the way then pull again sort of deal.
I have now removed that regulator and installed a barbed fitting to join the lines back up, it’ll start now without pinching that line, however it still takes a few pulls usually
