I posted a while ago that my new engine was bogging down if I tried to rev from idle. We came to a consensus that it was still breaking in and to wait it out. I've gone through around 2 gallons of gas at 30:1 and it behaves the exact same way. I'm almost out of this tank and I'm not sure if I should go to my normal 50:1 for the next tank or stick with the 30:1 since it still seems to be breaking in. Can running a higher oil ratio bog it down? Could it already be broken in and the bogging be a product of too much oil? Everything else like fuel air ratio seems fine, spark plug is chocolaty brown. Thanks for any help.
