Hey there everyone 3 weeks ago I bought a 19ft wellcraft with a 1996 Johnson 112 spl on it I'm new to boating repair and easy fixs so I don't know much I took the boat out for the first time and it ran great hit the throttle and it tflew threw the water sounded great ran great but when I'd come to an idle it would shut off and I'd have to use the throttle to get it cranked back up so everyone was telling me to get the carb cleaning done and I took it to a local shop and told him what all was going on and he said he would take a look and change everything and try and find out what is going on called me back 3 days later and told me tha. He had checked the compression before he did anything and that the #1 cylinder was at 90 and the one below it was at 130 and the other 2 on the left were at 120 then he told me I needed to get the number one piston replaced is this my only option or is there a possible smaller problem that it could be thanks for the help it is very helpful
