looking to put carbs on a motor i have. would like to go fuel inj. but don't have the money for a pcu now. here is what i have: 225 pm motor. it has a half cut exhaust, 260 port height, behind the liner ports blended. will have tight pump gas heads. no rod slot work. have wh-20's. i live in va, so close to sea level. this is a bass boat motor(gambler). not racing looking for a good all round and don't want to change jets all the time. looking to buy jets one time. would like to have the exact jets and setup and go. but i know that is not probably going to happen. looking for a close assorted reccomdation. bought these to learn on so any info would be great.

I bet U would..LOL.......I wish I wuz that good!!!!:D

If, and I say IF this mota wuz mine, I would start wit a set ov .078's in tha mains and .048s in tha idle holes!!!.....It may be a tad rich on bottom, but ya never know till ya try....We run sum 20's on a 2.5 SS mota turn'in 9300 and run .074's in tha mains.,...078's should be rite ther, but if ya feel skeer'd, .080's won't hurt ya!!......

Ever one ov theze thangz is differnt, and NO 2 have tha same appitite fer fuel, so they'z NO sur setup!!!:eek:
