yehh i know the jets are too big but it was still running fine even though it had a lumpy idle i was going to down size the jets but was thinking of putting a cam in so the mechanic said to leave them for now. Yeh only had to use the choke for like 5 secs if even that to start it but only on very cold mornings. As for fuel consumption thats why i choose 95 octane to get better fuel economy and after running two tanks i started getting this problem that why i thought maybe the higher octane fuel maybe the issue as it was already over fueling with the bigger jets now with the better fuel it cant handle it??
