Ok Merc issues

[spareparts]

if it didn't make any difference when you squezed the bulb, then push the key in to chole the motor, if it picks up, you have a fuel issue between the fuel line and the intake, if it bogs down when you push in the key switch, it sounds electrical

So the heat issue is normal, ok I just wanted to make sure!!

Therm, I planed on doing the filter and bowls, I am also going to replace the filter. The fuel pump is big and weird shaped so it must be the old one as you say??

Thanks spare thats easy ton do, thanks when I get it in the water thats just what I will do, if and when it bogs down again.

Ok Bs hurry up over!!

Thanks guys!!

MJ. second what ferm said, my merc runs 15 to 20 degrees hotter when between 1500 & 2500 rpms. they really don't seem to like trolling. I'm assuming you taken the oil injection system off, if not , that might be a prob. on hitting the choke, not sure if those carbs have a butterfly or a gas pump that pumps a shot of gas to the carb. might make a difference to what spare was checking

Old style MERCS used the actual choke butterfly's. If it is an enricher style with the fuel solonoid, then it won't work if fuel pressure isn't present.

no oil injection, all taken off and mix 50:1

87 175 2.4

Oil injection was removed and it's got the enrichner. It's a mid 80's merc.

Good point Ferm, If it bogs down the engine when you push in the key switch, then you know its not fuel, if it doesn't do anything, it could still be fuel, your not getting it to the enrichener as well as the carbs. If it picks up when you hit the enrichener, then you know its down stream of the enrichener
