so i have been having a 'miss' at a little over half throttle.. its been to 3 different mechanics and spent $1300 on this thing... in the shop they have put in new power pack. spark plugs. spark plug wires. cleaned and rekitted all 6 carbs. new fuel lines. a fuel water seperator...... problem...
i have a 92 johnson 150 fast strike on a 24 ft pontoon... i have had it in the shop twice in a month and 1300$ later still no fix... starts easy idles out of the cove and up to about 3/4 throttle (23mph) all is good... give it a little.more throttle and the motor runs rough and missing/losing...
