Hi all,
I'm newb so just correct me with the jargon and stuff. I have a Benelle M50 Andretti 2009, with a QJ1E40QMB-4. Carb is a Leader PZ19JB 19mm. I am having problems with a cold start. Here are the symptoms.
Outside Temp Range. 40 - 65F
1. Usually cranks in 5 to 10 seconds, not sure what is normal here.
2. Sometimes it idles normally and I can let it warm up.
3. Sometimes it ebbs and flows between idle and fast during warm up.
4. Sometimes it idles really low and keeps going dead.
If I don't let it warm up, the first time I stop, when the distance is short, it just bogs down when you throttle it and eventually dies. After you get past this point it runs great. Acceleration is great, usually run 3/4 throttle to maintain 35mph. It seems to struggle going up steeper hills though. Not sure if this is a variater weight problem or some thing else. Anyway, with the idle/acceleration problem. Could it be a malfunctioning enrich valve or do the PZ19JB carb just do this? Is there a better fuel delivery system?
Thanks for any input that you may have.
Mike
