JOHNSON 130HP CARBURETOR QUESTION - REBUILD ADVISE

[joe-doggs]

Dear friends,

I have a 1996 Johnson 130Hp Looper - It was in storage for 3 years - I will not start w/o starting fluid ( ether ) & will only continue running by pulsing the electric primer.

I have checked the float bowls - they are full of "green" gas - IE looks like VRO is working.

Ive checked the fuel pump - it pulses out of the VRO pump during crank - I havent checked the pressure though - but it does pulse gas.

Its got a healthy cranks speed & spark - Ive checked these & it will start on starting fluid OR using the electric primer.

Seems obvious its the carbs - but, how could all four be bad ?

Anything special about doing a Johnson looper carb rebiuild ? - I done many rebuilds in my life .

Couple questions:
1) OMC says not to use chlorinated carb cleaners ?
2) Any tips appreciate - any reason to buy the OMC jet removal tool ?
3) How are Sierra carb kits compared to OEM - any reason to use OEM over after market ?

Thanks !

All 4 carb bodies need cleaning because they all sat for the same length of time. Very common. I wouldn't run it anymore until you get the carbs soaked and new kits installed. Remember, the lube for the pistons is in the gas. No lube -- no oil. Pistons don't like that too much.

Might want to lay off the ether too, it will strip away any oil that is remaining on everything. You shouldn't have to use it at all.
