so pretty new to gas boats. I have a 26cc that wont run when hot. if you can get it to fire off it dies immediately. even then has to be choked a ton. once cooled back down fires right up and runs through a whole 500ml bag. some back story its a used engine I blew it up a month ago running it onto the shore when the radio box switch glitched. New top end installed, fresh carb, fresh diaphragm, no leaks in the bottom end and cases torqued. tried a 2nd carb, same issue. carb isolator not blocked or upside down gaskets used and could be replaced but seem adequate. all fresh seals on the exhaust. fresh gas, I put the last batch on the shelf and got brand new gas to start over with. fresh plug NGK CR7H. tried 2 different pickups.
coil? it also kind hunts at idle revving high for a bit then low again. worse when hot. needle settings Ive tried are L- 1.5 out to 2.5 out, generally 2-1/8 out. H needle 1-1/8 to 1-1/4 out. WT257 carb....again new diaphragms and cleaned out screen, rebuild kit. runs fine on the water, just wont start after a run. has to cool all the way down.
