right now im using the walbro 255 and it fails quite often, does anybody else have problems with it. does the 190 work and last longer, and whats the difference if i get that one. also will it handle boost and nitrous well.

 

My GSS342 is still good after many years...

 

thanks, im having starting issues when its cold out, and fuel pump came to mind.

 

Sounds like something with the cold start system... Try switching the key to the "on" position without starting for 3 seconds before cranking her over. Maybe that will help?

I would stick with the 255lph hp version for boosted applications if you do need to replace it...

 

thanks chunger, turns out its my cam position sensor.
