The best way I have found is to let the prime (lift) pump run and press on the comuchuck fitting on the gear pump then start it and let it run it going to stumble for a few minutes then it should run better

I let it run for prolly 2 minutes then I shut it off and posted here I went out there earlier and started it back up and it idled fine till I gave it fuel then it started stumbling again at idle as well... I'll let it idle for a few minutes and see what happens thx I appreciate the help
