Just got back from 3 days on the river, had an issue- motor gets right out of the hole and on plane good and will run at 4500-5000rpm all day (runs really good) but if i try to punch it for wot it approaches 5500rpm and then looses power(feels like i let off the throttle) and then itll start surging up and down (rpms)untill i back off throttle to 4500 rpm which it then will run all day. Just rebuilt fuel pump before trip couse i thought that was the prob. I do have one of those glass in line fuel filters, should i get rid of it? Does this on both fuel tanks.
Engine is 1975 70hp, boat is a 1965 16` starcraft (in my pic) timing is correct according to joe reeves method and compression is good.
Thanks in advance for any help, xj
